DESC:FIELD OF THE INVENTION

The present disclosure generally relates to kilns, and more particularly, the present disclosure relates to a system and a method for homogenously baking earthen objects in a kiln using Refused Derived Fuel (RSF) as a fuel.

BACKGROUND

Earthen objects such as bricks and tiles are widely used in the construction of residential and commercial buildings. Herein, the bricks are formed by using an earthen material such as clay. Further, the bricks are baked to transform the raw bricks into baked bricks in a kiln, such that the baked bricks gain enough strength to withstand heavy loads. Currently, the bricks are baked by heat generated from burning different fuels including coal, wood, and sawdust.

However, the use of the stated fossil fuels for baking comes with significant drawbacks such as a low efficiency as a huge volume of fuel is needed to generate the required amount of heat. Further, the burning of fossil fuels generates a large amount of residues such as ash that need to be handled separately usually, the burning of the fossil fuels generates one or more emissions that have a significant impact on the environment including environmental pollution, climate change, deforestation, habitat destruction, and health hazards. Thus, the existing baking process contributes to environmental degradation and health hazards due to the emission of pollutants.

Additionally, in the existing kilns, the earthen objects are stacked together and burnt altogether by the fossil fuels. The feeding of fossil fuel is controlled manually and needs to be monitored continuously to maintain the required heat for the baking process. This type of manual supervision is time-consuming, exhaustive, and less efficient. Further in the traditional kilns, the heat is generated and supplied from a single point of source resulting in uneven baking of the earthen objects. The earthen objects closer to the heat source may be burnt, the middle-stacked objects may be baked, and the higher stacked objects may be underbaked.

Thus, in view of the above, it is desirable to provide a system and/or a method that can eliminate one or more of the above-mentioned problems associated with existing art.

Furthermore, the hot gas is converted into the cold air when the hot gas flows through the earthen objects. Moreover, at least one outlet opening is formed on the walls of the baking chamber adjacent to the plurality of inlet openings and fluidically connected with the cold air duct. The at least one outlet opening is adapted to egress the cold air from each of the baking sections to the cold air duct.

In another embodiment, an airflow kiln for baking earthen objects is disclosed. The kiln includes a hot gas duct adapted to allow ingress of hot gas into the kiln for baking the earthen object and a cold air duct adapted to allow egress of cold air from the kiln posting baking the earthen object. The kiln further includes a baking chamber comprising a plurality of baking sections fluidically connected with the hot gas duct and the cold air duct and adapted to accommodate the earthen objects. Further, each of the baking sections includes a plurality of inlet openings formed on the walls of the baking chamber and fluidically connected with the hot gas duct. The plurality of inlet openings is adapted to uniformly dispense the hot gas into each of the baking sections to homogenously bake the earthen objects. Furthermore, the hot gas is converted into the cold air when the hot gas flows through the earthen objects. Moreover, at least one outlet opening is formed on the walls of the baking chamber adjacent to the plurality of inlet openings and fluidically connected with the cold air duct. The at least one outlet opening is adapted to egress the cold air from each of the baking sections to the cold air duct.

In yet another embodiment, a method for baking earthen objects is provided. The method includes burning a waste material in an incineration unit to generate hot gas. Further, the methods include filtering the hot gas in a filtration unit to remove suspended ash particles from the hot gas supplying hot gas. Then, the method includes supplying the ash-free hot gas from the incineration unit to a hot gas duct of a kiln. The method further includes dispensing via a plurality of inlet openings, the hot gas from the hot gas duct into each baking section from among a plurality of baking sections of the kiln. The plurality of baking sections is adapted to accommodate the earthen objects. Thereafter, the method includes steps of baking the earthen objects by uniformly dispensing the hot gas on the earthen objects for a predetermined time. The hot gas is converted into cold air when the hot gas flows through the earthen objects. Finally, the method includes steps of removing the cold air from each baking section to a cold air duct via at least one outlet opening.

The advantages of the system for baking the earthen objects are now explained. The system utilizes discarded RDF/MSW, plastic waste, and non-hazardous combustible waste and burns efficiently to achieve the required temperature to bake the earthen objects. The system provides a sustainable and efficient solution for converting RDF/MSW, plastic, and non-hazardous combustible waste into energy while minimizing environmental impact. Further, the implementation of the system provides a cost-effective and environmentally friendly way of waste management and energy generation, which contributes to a cleaner environment. Additionally, the system provides a continuous and controlled hot gas distribution over the earthen objects. This reduces the need for manual intervention and monitoring.

Figure 1 illustrates a schematic view of a system 100 for homogenous baking of earthen objects, in accordance with an embodiment of the present disclosure. Referring to Figure 1, the system 100 may be adapted to burn a waste material 108 in an incineration unit 102 to generate hot gas. Further, the generated hot gas is uniformly supplied to a kiln 106 for homogenously baking earthen objects.

In an embodiment, the waste material 108 may include but is not limited to, Refuse-derived fuel (RDF), Municipal Solid Waste (MSW), plastic waste, and non-hazardous combustible waste. The waste material 108 is adapted to be burnt in the incineration unit 102 to generate the hot gas for baking the earthen objects. In a non-limiting embodiment, the earthen objects include, but are not limited to, clay potteries, bricks, and ceramics made by using an earthen material.

The system 100 may be adapted to bake earthen objects in the kiln 106. It is to be understood by those skilled in the art that the system 100 may be adapted to homogeneously bake any earthen objects, without departing from the scope of the present disclosure. In an embodiment, the system 100 includes but is not limited to, the incineration unit 102, an air filtration unit 104, and the kiln 106. The waste material 108 may be stored in a separate storage area.

The incineration unit 102 is adapted to burn waste materials 108 to generate the hot gas. The waste material 108 may be transported from the storage area to the incineration unit 102 by a conveyor belt 110. The conveyor belt 110 may continuously feed the incineration unit 102 by supplying the waste material 108 for combustion.

In an embodiment, the incineration unit 102 may be a reciprocating grit boiler. The incineration unit 102 may include a moving or a reciprocrating grate that continuously moves the waste material 108 in the combustion chamber ensuring complete combustion and minimizing the formation of unburnt material.. Further, the incineration unit 102 may be provided with a forced aeration unit 122 to control the flow rate of air and maintain optimal combustion conditions in the combustion chamber. The forced aeration unit 122 may be equipped with sensors and controls to monitor and adjust the airflow rate to optimize combustion conditions and minimize emissions. The forced aeration unit 122 is configured to supply pressurized air to a bottom of the grate to ensure complete combustion of the RDF in the incineration unit 102. In an embodiment, the forced aeration unit 122 is a Forced Draft (FD) fan.

In an embodiment, the waste material 108 in the combustion chamber of the incineration unit 102 is burnt to achieve a temperature output above 850°Celsius (C) having residence time of more than 2 seconds. In an embodiment, the residence time achieved in the incineration unit 102 is more than 4 seconds. The residence time allows for complete disintegration of dioxin furans and any other harmful gases that may have gotten generated due to the combustion of the RDF... It is to be understood that the incineration unit 102 may be modular and scalable and may be customized to accommodate different capacities of the waste material 108. The incineration unit 102 may also be integrated with other waste management systems such as sorting and shredding unit for effective transportation of the waste material 108.

Further, the air filtration unit 104 may be fluidically connected to the incineration unit 102 and adapted to receive hot gas from the incineration unit 102. Further, the air filtration unit 104 may be configured to remove ash from the hot gas received from the incineration unit 102 and supply hot gas free from ash to the kiln 106. The air filtration unit 104 may be provided with a plurality of waffles 120 positioned alternatively opposite to each other. When the hot gas from the incineration unit 102 passes through the plurality of waffles 120, the suspended ash particles may get trapped in the plurality of waffles 120 allowing only the hot gas to flow through. The hot gas free from the ashes may be further supplied to the kiln 106 to bake earthen objects. The constructional and operational details of the kiln 106 for homogenous baking of earthen objects are described in detail in subsequent paragraphs.

Figures 2A and 2B illustrate a top view and a front view of the kiln 106 of the system 100 for homogenous baking of earthen objects respectively, in accordance with an embodiment of the present disclosure. For the sake of brevity figures 2A and 2B are described together. The air filtration unit 104 may be fluidically connected to the kiln 106. The filtered hot gas free from ash may be supplied to the kiln 106. The kiln 106 may include a hot gas duct 202, a cold air duct 204, and a baking chamber216. The hot gas duct 202 may be adapted to allow the ingress of hot gas into the kiln 106 from the air filtration unit 104 for baking the earthen objects and transforming the hot gas into cold air. Further, the cold air duct 204 may be adapted to allow the egress of cold air from the kiln 106 posting baking of the earthen objects.

Further, the baking chamber 216 may include a first wall 212 and a second wall 214, the second wall 214 disposed opposite to the first wall 212 defining a space 218 in between. The first wall 212 of the baking chamber216 may further include a plurality of baking sections fluidically connected with the hot gas duct 202 and the cold air duct 204 and adapted to accommodate the earthen objects. Further, each of the baking sections 206 may include a plurality of inlet openings 208 formed on the first wall 212 of the baking chamber 216 and fluidically connected with the hot gas duct 202 and at least one outlet opening 210 formed on the first wall 212 of the baking chamber 216 and fluidically connected to the cold air duct 204. In an embodiment, the at least one outlet opening 210 may be formed adjacent to the plurality of inlet openings 208 in the first wall 212 of the baking chamber 216.

The space 218 defined in the baking chamber 216 is the area in the kiln 106 adapted to accommodate the earthen objects to be baked. The earthen objects to be baked may be arranged in the plurality of baking sections 206 of the baking chamber 216. In an embodiment, the baking sections 206 in the plurality of baking sections may be arranged parallelly with respect to each other. The hot gas from the incineration unit 102 passes through the air filtration unit 104 and through the plurality of inlet openings 208 provided in each of the baking sections 206 via the hot gas duct 202. The plurality of inlet openings 208 is adapted to uniformly dispense the hot gas into each baking section 206 to homogenously bake the earthen objects.

In an example, the plurality of inlet openings 208 includes a first set of three openings 220 formed in a parallel orientation relative to each other in a bottom portion of each baking section and a second set of three openings 222 formed in a parallel orientation relative to each other in a middle portion of each baking section. The hot gas flows from the bottom portion to an upper portion of each baking section and the middle to the upper portion of each baking section to facilitate the homogenous baking of the earthen objects.

Further, the hot gas may be subjected to flow over the earthen objects arranged in the plurality of baking sections 206 in the baking chamber 216. When the hot gas flows through the earthen objects, the heat from the air may be absorbed by the earthen objects during the process of baking and converted into the cold air. After the baking process, the cold air may be egressed from the plurality of baking sections 206 via the at least one outlet opening 210. In an embodiment, the at least one outlet opening 210 may be formed in the bottom portion of each of the baking sections 206 adjacent to the plurality of the inlet openings 208.

The system 100 may be a high-pressure system that creates a pressure differential between the incineration unit 102, the air filtration unit 104, and the kiln 106. This differential pressure facilitates a seamless flow of the hot gas through different units such as the incineration unit 102, the air filtration unit 104, and the kiln 106 in the system 100. Also, the differential pressure facilitates the egress of cold air from the kiln 106 after the baking process. The cold air after the baking process is fed to a flue gas treatment plant 112 and from the flue gas treatment plant 112 the treated cold air is passed through a bag filter 114. Furthermore, the treated cold air is sucked from the bag filter 114 by an Induced Draft (ID) fan 116 and released into the environment via a chimney 118. The differential pressure is created in the system 100 by the ID fan 116 by pulling used hot gas from the kiln 106.

The present disclosure further relates to a method 300 for baking the earthen objects as shown in Figure 3. The order in which the method steps are described below is not intended to be construed as a limitation, and any number of the described method steps can be combined in any appropriate order to execute the method or an alternative method. Additionally, individual steps may be deleted from the method without departing from the spirit and scope of the subject matter described herein.

Figure 3 illustrates a flow chart depicting a method 300 for baking earthen objects, according to an embodiment of the present disclosure. The method 300 for baking the earthen objects may be performed by using the system 100 as shown in Figure 1. The method 300 begins at step 302 by burning the waste material 108 in the incineration unit 102 to generate the hot gas. In an embodiment, the waste material may be one of Refused Derived Fuel (RDF), Municipal Solid Waste (MSW), plastic waste, and non-hazardous combustible waste. Next at step 304, the hot gas may be filtered in the air filtration unit 104 to remove suspended ash particles from the hot gas. Thereafter in step 306, the ash-free hot gas is supplied from the incineration unit 102 to the hot gas duct 202 of the kiln 106. Next in step 308, the hot gas is dispensed via a plurality of inlet openings 208 from the hot gas duct 202 into each baking section 206 from among a plurality of baking sections 206 of the kiln 106. The plurality of baking sections 206 may be provided in a baking chamber 216 adapted to accommodate the earthen objects.

Further at step 310, the earthen objects may be baked by uniformly dispensing the hot gas on the earthen objects for a predetermined time period. When the hot gas the flows through the earthen objects, the heat in the hot may be absorbed by the earthen objects converting the hot gas into a cold air. Finally, at step 312, the cold air may be removed from each of the baking section 206 to the cold air duct 204 via the at least one outlet opening 210.

The present disclosure further relates to depicting a method 300 for dispensing hot gas into the kiln 106 as shown in Figure 4. The order in which the method steps are described below is not intended to be construed as a limitation, and any number of the described method steps can be combined in any appropriate order to execute the method or an alternative method. Additionally, individual steps may be deleted from the method without departing from the spirit and scope of the subject matter described herein.

Figure 4 illustrates a flow chart depicting the method for dispensing hot gas into the kiln 106, according to an embodiment of the present disclosure. The method 400 begins at step 402 by dispensing hot gas via a first set of three openings 220 in each of the baking sections 206. Next at step 404, the hot gas dispensed in each of the baking sections 206 may be circulated from the bottom portion to the upper portion. The hot gas dispensed from the first set of three openings 220 may flow from the bottom portion to the upper portion in each of the baking sections 206. Further at step 406, the hot gas may be dispensed via a second set of three openings 222 in each of the baking sections 206.

Finally, at step 408, the hot gas may be circulated from a middle portion to the upper portion in each of the baking sections 206. The hot gas dispensed from the second set of three openings 222 may flow from the bottom portion to the upper portion in each of the baking sections 206. The dispensation of the hot gas via the first set of three openings 220 and the second set of three openings 222 uniformly distributes the hot gas in each of the baking sections 206. This uniform distribution of hot gas facilitates in homogenous baking of the earthen objects placed in each of the baking sections 206 of the kiln 106.

The advantages of the system 100 for baking the earthen objects are now explained. The system 100 utilizes discarded RDF/MSW, plastic waste, and non-hazardous combustible waste and burns efficiently to achieve the required temperature to bake the earthen objects. The system 100 provides a sustainable and efficient solution for converting RDF/MSW, plastic, and non-hazardous combustible waste into energy while minimizing environmental impact. Further, the implementation of the system 100 provides a cost-effective and environmentally friendly way of waste management and energy generation, which contributes to a cleaner environment. Additionally, the system 100 provides a continuous and controlled hot gas distribution over the earthen objects. This reduces the need for manual intervention and monitoring.

The hot gas generated during the incineration of RDF/MSW, plastic, and non-hazardous combustible waste is efficiently transferred to the kiln 106 and effectively circulated facilitating in efficient curing and hardening of the earthen objects. The circulation of the hot gas inside the kiln 106 provides for efficient and uniform baking of the earthen objects in the kiln 106.

While specific language has been used to describe the present disclosure, any limitations arising on account thereto, are not intended. As would be apparent to a person in the art, various working modifications may be made to the method in order to implement the inventive concept as taught herein. The drawings and the foregoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. ,CLAIMS:1.
