TECHNICAL FIELD:

Present disclosure relates in general to a field of metallurgy. Particularly, but not exclusively, the present disclosure relates to carbonization of coal. Further embodiments of the present disclosure are directed to a system and a method for visualizing carbonization of coal in real-time

BACKGROUND OF THE DISCLOSURE:

Coke is a solid carbon fuel and carbon source which is typically manufactured from coal and is used in numerous applications, for example, to melt and reduce iron ore in the production of steel. Coke ovens have been used for many years to convert coal into coke in a process known generally as “coking.” During the coking process, finely crushed coal is heated under controlled temperature conditions to devolatilize the coal and form a fused mass of coke known as a “cake” having a good porosity and strength. In one known process, coke used for refining metal ores is produced by batch feeding pulverized coal into an oven which is sealed and heated to high temperatures under closely controlled atmospheric conditions.

Melting and fusion process undergone by the coal particles during the heating process is an important part of coking. The degree of melting and degree of assimilation of the coal particles into the molten mass determine the characteristics of the coke produced. In order to produce the strongest coke from a particular coal or coal blend, there is an optimum ratio of reactive to inert entities in the coal. The porosity and strength of the coke are important for the ore refining process and are determined by the coal source and/or method of coking.

Coal particles or a blend of coal particles are charged into hot ovens, and the coal is heated in the ovens in order to remove volatile matter (“VM”) from the resulting coke. The coking process is highly dependent on the oven design, the type of coal, and conversion temperature used. It is important to know the conversion temperature of the coal to coke to obtain best properties of the coke. Conventionally, there is only thermocouple-based temperature measuring device to obtain the center mass temperature of the coal. However, conventional devices have myriad disadvantages. For instance, from the conventional devices it is difficult to visualize the carbonization process and parameters such as soaking time, transition state, optimum coking temperature etc.

The present disclosure is directed to overcome one or more limitations stated above or any other limitations associated with the conventional arts.

FIG.1 typically illustrates one of a plurality of coke oven (100) of a coke oven battery. The coke oven batteries may include the plurality of coke ovens (100) arranged in a side-by-side configuration along a longitudinal dimension of the coke ovens (100). Each of the plurality of coke ovens (100) defines an input portal and an outlet portal. In the coke making process [also referred to as carbonization process/coking which may be alternatively used], a mass of coal or coal cake may be loaded into the coke oven batteries [i.e., each of the plurality of coke ovens] through the inlet portals and baked at higher temperatures ranging from about 950°C to about 1350°. Once the coal cake is “coked out” or fully coked, the resulting coke loaf [unquenched coke] may be removed from the coke oven batteries and may be transferred to the quenching car [also referred to as train car, hot car] through the outlet portal to the quenching car. It is important to set the correct time frame for the carbonization process to get desired properties. In the present disclosure to set the effective parameters for coking process in subsequent coking operations, the parameters are found by tracking the carbonization process for a given composition of coal in real time. Such parameters may include optimum time of coking, solutionising and the like, which in turn increases productivity of coke ovens (100). The present disclosure discloses a system and method for visualizing carbonization of coal in the real-time. In the corresponding figures, the system is depicted by referral numeral (10). In the forthcoming embodiments, the system (10) for visualizing carbonization of coal in real time will be elucidated with respect to FIG.1.

Referring now to FIG.1, the system (10) according to the present disclosure may include a plurality of probes (1). Each of the plurality of probes (1) may be made of electrically conductive materials. In an embodiment, the diameter of each of the plurality of probes (1) may range from about 6mm to about 12mm. Further, the length of each of the plurality of probes may range from about 120mm to about 170mm. The dimension of each of the plurality of probes should not be construed as a limitation of the present disclosure as the dimension of each of the plurality of probes (1) may vary based on dimensions on the coke oven in which it is employed. In an embodiment, the plurality of probes (1) may be used along with test setup coke oven such as carbolite oven. In some embodiments, the plurality of probes (1) may be used along with the employed for coking process. The plurality of probes (1) may be structured to be accommodated in the coke oven (100) in which the coal cake may be contained for the carbonization process. In an embodiment, the coke ovens (100) may be defined with one or more provision along the wall at pre-defined positions to receive the plurality of probes (1). Each of the plurality of probes (1) may be ingressed into the coke oven (100) through the one or more provisions defined on the wall. Each of the plurality of probes (1) may be ingressed into the coke oven (100) up to a pre-determined depth from a wall of the coke oven. The pre-determined depth may range from 80mm to 120 mm from the wall of the coke oven (100). Also, each of the plurality of probes (1) may be positioned at a pre-determined distance apart from each other when ingressed into the coke oven (100). The pre-determined distance may range from about 40mm to about 60mm.

Further, the plurality of probes (100) may be electrically coupled to a power supply module (2). The power supply module (2) may be an external power source or an internal power source. The power supply module (2) among other components may include a DC power supply source, a multimeter [not shown], and a switch [not shown]. In an embodiment, the DC power supply source may be digitally regulated DC power supply. In an embodiment, each of the plurality of probes (1), a DC power supply source, a multimeter, and a switch may define an electrical circuit. The power supply module (2) may be configured to apply pre-determined voltage to each of the plurality of probes (1). The pre-determined voltage may range from 20V to 24V. Further, the system (10) includes a control module (M) that may be communicatively coupled to the power supply module (2). The control module (M) may be configured to determined one or more electrical parameters across the plurality of probes (1) at pre-determined time intervals during carbonization. Based on the determination of the one or more electrical parameters, the control module (M) may generate an impedance curve [refer FIG.2 and 3]. The impedance curve may correspond to thermal profile of carbonization of coal.

Referring to FIG.2, the impedance curve may be a time versus current curve. The impedance curve defines a first linear curve indicative of non-conduction state. The first linear curve may correspond to the non-conduction state of the coal when it is initially loaded into the coke ovens. In the solid state, the coal offers maximum resistance to the flow of current that is supplied to the plurality of probes (1). The resistance offered by the coal to the flow of current may be visualized from the plot of resistance vs time shown in FIG.3. Further, a substantially vertical curve [referring to FIG.2] in the impedance curve may be indicative of transition state in the carbonization of coal. The transition state of in the carbonization process is indicative of coal being converted into coke. As the coal begins to covert to coke, the resistance offered to the flow of current across the plurality of probes (1) reduces gradually and attains a peak. When the substantially vertical curve is at the peak it may indicate that the coal has reached plastic zone. Once the plastic zone is achieved, the conduction of the plurality of probes (1) remains constant over a period which is represented by a second linear curve. The second linear curve [refer to FIG.2] in the impedance curve may be indicative of soaking time of coke during carbonization. In an embodiment, the second linear curve may also be indicative of completion of carbonization process. In an embodiment, the impedance curve of FIG.2 may be displayed in a display unit (D) which may be associated with the control module (M). The control module (M) may be configured to display the impedance curve through the display unit (D). In an embodiment, the system (10) of the present disclosure enables tracking and sensing the gradual change in electrical parameter of the stamped coal cake in the heating process which may give an internal picture of the burn front movement. The burn front movement may be a window to the sensing method to complete carbonization of the coal in the coke oven battery. The result obtained by the system (10) above may be monitored and it may be observed that there is a radical shift of electric current value during carbonization.

FIG.4 is an exemplary embodiment of the present disclosure, illustrating a flowchart of a method for visualizing the carbonization of coal in real time.

As illustrated in FIG.4, the method comprises one or more blocks illustrating a method for visualizing the carbonization of coal in real time. The method may be described in the general context of computer-executable instructions. Generally, computer-executable instructions can include routines, programs, objects, components, data structures, procedures, modules, and functions, which perform functions or implement abstract data types.

The order in which the method is described is not intended to be construed as a limitation, and any number of the described method blocks can be combined in any order to implement the method. Additionally, individual blocks may be deleted from the methods without departing from the spirit and scope of the subject matter described herein. Furthermore, the method can be implemented in any suitable hardware, software, firmware, or combination thereof.

In operation, the coal cake may be charged into the coke ovens (100) for carbonization process. Once the coke oven (100) is charged with coal cake, the plurality of probes (1) may be inserted into the coke oven (100) [as shown at block 101]. The plurality of probes (1) may be ingressed into the coke oven (100) through the one or more provisions defined on the wall of the furnace as described in the earlier embodiments. Once the plurality of probes (1) is ingressed into the coke oven (100), the power supply module (2) may be triggered to apply pre-determined voltage across the plurality of probes during the carbonization process- [as shown at block 102]. As shown at block 103, the control module (M) may be configured to monitor one or more electrical parameters across the plurality of probes (1) at pre-determined intervals during carbonization to generate am impedance curve.

Exemplary Experimental analysis

Following paragraphs may be illustrate exemplary experimental results illustrating a test performed using the system (10) of the present disclosure. As shown in FIG.1, two probes may be placed across the stamped mass of the coal cake at a distance of 50mm. A fixed DC voltage of 24V may be applied across the two probes and the current may be measured at different time during the process of carbonization in a 7Kg carbolite oven. Various- experiment has been carried out by measuring the current and resistance changing parameter. Two trails have been conducted which depicts the true representation of carbonization. At first trail, the coal cake is being subjected to a constant 23.6 V DC source though the two probes inserted at 50mm gap and depth of 100mm inside the coal. Duration of the coal to coke conversion and the current flowing through the coal cake is being logged with respect to time [refer FIG.2]. In the second trial, the resistance is measured with standard multimeters across the coal cake in the two metallic probes inserted as earlier described and data being logged with respect to time [refer FIG.3]. Both trials have been conducted with coke mass of 9.40 Kg and of 10% moisture content as per the standard in 7Kg carbolite oven stamped cake dimension 336*90*270 [L*W*H] and of same blend. The conductivity variation of the coal cake during the process of carbonization may be visualized from the impedance curve obtained [refer FIG.2 and 3]. The impedance curve may be used to visualize the complete carbonization process and track the coal to coke formation. The visualization of coal to coke enables the operator to determine optimum time and temperature for coal to coke formation. As seen from FIG.2, the impedance curve is depicted which is a time versus current curve. The impedance curve defined a first linear curve indicative of non-conduction state where the coal is in its solid form. Over a period of time and as seen in the impedance curve, the first linear curve progresses into a substantially vertical curve indicative to transition state in the carbonization process. That is in the transition state, the coal starts to convert to coke. Once the coal is completely converted to coke, the substantially vertical curve progresses to the second linear curve which is indicative of at least one of soaking time of coke and end of carbonization process. Using the impedance curve, the operator would be able to determine optimum soaking time for given batch of coke, so that the same can be set for a particular batch of coke processed in in the coke ovens.

In an embodiment, the system (10) according to the present disclosure is const effective and requires minimal maintenance. Also, the system (10) of the present disclosure helps to identify or determine the parameters required for carbonization accurately. The system (10) of the present disclosure ensures optimum soaking time of coke to obtain best properties of coke. The system (10) enables operator to visualize the carbonization of coal to coke in real time.
