BY

STEEL AUTHORITY OF INDIA LIMITED, A GOVERNMENT OF INDIA ENTERPRISE, HAVING ITS ADDRESS AT RESEARCH & DEVELOPMENT CENTRE FOR IRON & STEEL, DORANDA, RANCHI-834002, STATE OF JHARKHAND, INDIA

THE FOLLOWING SPECIFICATION PARTICULARLY DESCRIBES THE INVENTION AND THE MANNER IN WHICH IT IS TO BE PERFORMED. 

TECHNICAL FIELD OF THE INVENTION
[0001] The present disclosure generally relates to coke ovens and more particularly relates to a system and method for providing uniform heating control and thermal profile management of the pilot coke ovens during heating and carbonization cycle.
BACKGROUND OF THE INVENTION
[0002] A Pilot coke oven is a complex laboratory oven. The existing coke oven (for example, a coke oven of 200kg) can be heated by electricity. The coke oven temperature in the existing coke oven is adjusted by manual control. Thus, an operator requires high technical expertise/skills for manually controlling the coke oven temperature in the existing coke oven. Additionally, attaining uniformity of the oven temperature in the existing coke oven is difficult due to manual control of the coke oven temperature.
[0003] In recent times, a control scheme is introduced for temperature control in the coke oven. In the existing control scheme, the heating elements
(e.g., electrical heating elements) are operated in manual mode. Further, due to the non-uniform resistance of the heating elements at various heating zones of the coke oven, the coke oven experiences temperature lagging in the various heating zones. To circumvent the aforementioned problem, a voltage input to a power controller operating the heating elements was manually increased. Moreover, with the aging of the power controller, capacity to carry high-magnitude current decreases. To that effect, the existing control scheme experiences over current tripping due to heating of the power controller.
[0004] Therefore, there is a need for a system architecture and a method for providing temperature control and temperature profile management in the coke oven, in addition to providing other technical advantages.

OBJECTIVE OF THE INVENTION
[0005] The main objective of the present invention is to provide a uniform heating and carbonization profile management system for pilot coke ovens for proper and authentic testing of coal samples.
SUMMARY OF THE INVENTION
[0006] An aspect of the present invention is to address at least the above-mentioned problems and/or disadvantages and to provide at least the advantages described below.
[0007] Accordingly, in one aspect of the present disclosure, a system for heating control in a pilot coke oven is disclosed. The system includes a plurality of power controllers. Each power controller of the plurality of power controllers is operatively coupled to a heating element of a plurality of heating elements installed in one or more heating zones of the pilot coke oven. The plurality of power controllers includes a thyristor-based single-phase full wave controller. Further, the system includes a central control system operatively coupled to the plurality of power controllers. The central control system is configured to provide a pulse signal to the plurality of power controllers based at least on temperature profile data. The pulse signal triggers the plurality of power controllers to operate the plurality of heating elements based at least on a phase angle control for at least attaining a set heating rate and providing uniform heating in each heating zone of the one or more heating zones of the pilot coke oven during heating and carbonization cycle.
[0008] Accordingly, in one aspect of the present invention, a method for providing heating control in a pilot coke oven is disclosed. The method includes transmitting, by a central control system, a pulse signal to a plurality of power controllers based at least on temperature profile data. The method further includes, in response to the pulse signal, triggering the plurality of power controllers to operate a plurality of heating elements installed in one or more heating zones of the pilot coke oven based at least on a phase angle control. The phase angle control associated with the plurality of power controllers adjusts a conduction angle of an alternate current (AC) signal of the plurality of power controllers, thus resulting in control of a magnitude of an average AC voltage and AC current associated with the plurality of heating elements. Further, controlling the magnitude of average AC voltage and AC current enables the plurality of heating elements to attain a set temperature at a set heating rate for providing uniform heating in each heating zone of the one or more heating zones of the pilot coke oven during heating and carbonization cycle. The method further includes facilitating, by the central control system, display of at least a temperature of each heating zone, a magnitude of voltage, current, and resistance associated with the plurality of heating elements in each heating zone, wall pressure, and charge height on a human-machine interface in real-time.

[0021] In the following description, for purpose of explanation, specific details are set forth in order to provide an understanding of the present disclosure. It will be apparent, however, to one skilled in the art that the present disclosure may be practiced without these details. One skilled in the art will recognize that embodiments of the present disclosure, some of which are described below, may be incorporated into a number of systems. However, the systems and methods are not limited to the specific embodiments described herein. Further, structures and devices shown in the figures are illustrative of exemplary embodiments of the presently disclosure and are meant to avoid obscuring of the presently disclosure.
[0022] Various embodiments of the present disclosure are further described with reference to FIG. 1 to FIG. 4.
[0023] FIG. 1 illustrates a simplified block diagram representation of an environment (100), in which at least some embodiments of the present disclosure can be implemented. Although the environment (100) is depicted to include one or a few components, modules, or devices arranged in a particular arrangement in the present disclosure, it should not be taken to limit the scope of the present disclosure. The environment (100) depicts a system architecture (102) for providing uniform heating control and temperature profile management in a pilot coke oven (104). The pilot coke oven (PCO) (104) may be a large-scale pilot coke oven (e.g., 300 kilograms (Kg)). The PCO (104) may be made of various types of refractory materials that require controlled heating and cooling to prevent damage due to unequal thermal expansions and phase changes. Further, the PCO (104) may be used for testing various coal blends with respect to its properties such as micum 10 (M10), M40, coke strength (CSR), CSI, etc. Generally, for testing of the coal blends or samples, the carbonization of coal blends in the PCO (104) is carried out in a temperature range of about 1040 degrees Celsius (oC) to 1060oC under different programmable rates of rise of temperature which will be explained further in detail.
[0024] Further, the PCO (104) is divided into one or more heating zones (represented as heating zones (Z1, Z2, Z3, Z4, Z5, and Z6)) for performing heating and carbonization of the coal samples in the PCO (104). In an example, the PCO (104) is divided into 6 heating zones as shown in FIG. 1, and it should not be considered for limiting the scope of the present disclosure. Alternatively, the number of heating zones may vary in the PCO (e.g., the PCO (104)) based on requirements. Further, the one or more heating zones (Z1-Z6) are installed with a plurality of heating elements (such as heating elements (106a, 106b, 106c, 106d, 106e, and 106f)). In other words, the heating elements (106a-106f) are installed in corresponding heating zones (Z1-Z6). In an embodiment, the heating elements (106a-106f) may be a resistor (i.e., resistor heating element). The heating elements (106a-106f) implemented as resistors are configured to provide thermal energy (or generate heat) when an electric current passes through. This form of generating heat by utilizing electric current refers to electrical heating.
[0025] The system architecture (102) includes a plurality of power controllers (108). The power controllers (108) may be a digital temperature controller. It is to be noted that, six power controllers (i.e., the power controllers (108)) are shown in FIG. 1 corresponding to the number of heating zones (Z1-Z6) and the heating elements (106a-106f) installed in the corresponding heating zone of the PCO (104). Each power controller of the plurality of power controllers (108) is operatively coupled to a heating element of the plurality of heating elements (106a-106f). In other words, each heating zone (Z1-Z6) includes a separate power controller. The power controllers (108) may be a thyristor-based single-phase full wave controller for phase angle control. The rating of the power controllers (108) may be single phase 160 amperes (A).
[0026] The system (102) further includes a central control system (110). The central control system (110) may be implemented as a programmable logic controller (PLC). The central control system (110) is communicably coupled to the power controllers (108), and a feedback apparatus (110) via a communication interface (120). For example, the communication interface (120) may be an 8-port E-switch. Further, the central control system (110) may be equipped with an uninterrupted power supply (UPS) system (not shown in figures). The central control system (110) may include a redundant central processing unit (CPU) with input/output (IO) cards, TC cards, etc. The central control system (110) operates in a closed loop Proportional Integral Derivative (PID) control and provides a pulse signal to the power controllers (108) based at least on temperature profile data. The temperature profile data may include at least a pre-carbonization heating profile and a carbonization heating profile (as shown in FIG. 2). Thus, it is to be noted that the PCO (104) is subjected to two heating cycles i.e., heating and carbonization cycle. In one embodiment, the central control system (110) may be associated with a database (not shown in figures) that stores programs or instructions for temperature profile control and safety control.
[0027] As explained above, the central control system (110) provides the pulse signal to the power controllers (108) based on the temperature profile data. The temperature profile data may be predefined for a particular heating and carbonization cycle. In this scenario, the pulse signal triggers the power controllers (108) to operate the heating elements (106a-106f) equipped in the heating zones (Z1-Z6) based at least on a phase angle control for attaining a set temperature at a set heating rate. It is to be noted that the phase angle control associated with the power controllers (108) adjusts a conduction angle of an alternate current (AC) signal of the power controllers (108). As a result, a magnitude of an average AC voltage and AC current associated with the heating elements (106a-106f) is adjusted accordingly, thereby enabling the heating elements (106a-106f) to attain a set temperature (e.g., 1040oC - 1060oC) at the set heating rate. Additionally, the power controllers (108) operate the heating elements (106a-106f) to provide uniform heating in each heating zone of the one or more heating zones (Z1-Z6) of the pilot coke oven (104) during heating and carbonization cycle.
[0028] In particular, the central control system (110) is configured to maintain uniform heating in each of the heating zones (Z1-Z6) based on feedback. The system architecture (102) includes the feedback apparatus (112) operatively coupled to the central control system (110). The feedback apparatus (112) provides feedback related to one or more parameters associated with the PCO (104) to the central control system (110) for enabling uniform heating control during the heating and carbonization cycle. The feedback apparatus (112) includes at least a plurality of temperature measurement devices (114), at least one linear variable differential transformer (LVDT) (116), and one or more load cells (118). The temperature measurement devices (114) may be equipped in each heating zone (Z1-Z6) of the PCO (104). The temperature measurement devices (114) may be a thermocouple (e.g., Platinum Rhodium -13% / Platinum). For example, the LVDT (116) may include an SLS-130 Linear potentiometer, 175 mm, 7KΩ. The temperature measurement devices (114), the LVDT (116), and the load cells (118) are configured to determine a temperature of each heating zone (Z1-Z6), wall pressure, charge height of the PCO (104), respectively, during the heating and carbonization cycle. Thereafter, information related to the temperatures of the heating zones (Z1-Z6), wall pressure, and charge height is transmitted by the feedback apparatus (112) to the central control system (110) in real-time.
[0029] The central control system (110) with feedback of the above-mentioned parameters generates the pulse signal to the power controllers (108). In an example scenario, the temperature of the heating zones (Z1-Z6) may be determined to be unequal based on the feedback. In this example, scenario, the central control system (110) triggers the pulse signal to the power controllers (108) corresponding to the real-time temperature profile data of the heating zones (Z1-Z6) received as feedback from the feedback apparatus (112). Thus, the power controllers (108) operate the heating elements (106a-106f) to maintain uniform heating in each heating zone (Z1-Z6) of the PCO (104). It is to be noted that, dynamic control of the heating elements (106a-106f) is implemented by the system (102) (or combined operation of the central control system (110) and the power controllers (108)) for providing uniform heating in each heating zone (Z1-Z6) of the pilot coke oven (104) based on the real-time temperature profile data of the PCO (104). To that effect, uniform and accurate heating control in all the heating zones (Z1-Z6) through the system (102) is achieved during the heating and carbonization cycle. Further time taken to achieve the set temperature during the carbonization cycle is reduced. Additionally, the system (102) provides authentic testing of coal samples due to uniform heating control and temperature profile management of the PCO (104).
[0030] Furthermore, the central control system (110) is configured to facilitate display of at least the temperature of each heating zone (Z1-Z6), the magnitude of voltage, current, and resistance associated with the heating elements (106a-106f) in each heating zone (Z1-Z6), wall pressure and charge height. Specifically, the central control system (110) is communicably coupled to a human-machine interface (122). The central control system (110) performs data logging of the aforementioned parameters determined by at least the feedback apparatus (112) and the power controllers (108) in real time. In addition, the above-mentioned parameters related to the PCO (104) are displayed on a display device (124) associated with the human-machine interface (122) in real-time. The human-machine interface (122) facilitates an operator to access the aforementioned parameters of the PCO (104) and allows the selection of heating and carbonization profile rates.
[0031] Referring to FIGS. 3A-3F, an example representation of the above-mentioned parameters displayed on the human-machine interface (122) in real-time during the heating and carbonization cycle is shown. It is to be noted that the above-mentioned parameters during the heating and carbonization cycle are exemplarily depicted as trend charts/graphs. Alternatively, any other representation can be used for showing the variation of the above-mentioned parameters over time.
[0032] It is to be noted that the magnitude of the voltage/voltage profile of the heating zones (Z1-Z6) is maintained uniform during the heating and carbonization cycle (as shown in FIG. 3A). Similarly, the current profile of the heating zones (Z1-Z6) is also maintained uniform in the heating and carbonization cycle (as shown in FIG. 3B). Thus, it is evident that the system (102) provides uniform heating control and temperature profile management of the PCO (104) in real-time. Further, the variation of wall pressure, charge height, coke mass temperature, and heating zone temperature in the carbonization cycle are shown in the respective FIGS. 3C, 3D, 3E and 3F. It is understood from the trend charts that, a) the center coke mass temperatures of coke is achieved at a faster rate due to uniform heating of each heating zones (Z1-Z6), and b) heating zone temperature and oven wall temperature data that the heating regimes at different temperature is aligned with temperature data of the temperature measurement devices (114). In addition, the difference in temperature of heating zones (Z1-Z6) and oven wall temperature can be maintained within 30°C.
[0033] FIG. 4 is a flowchart depicting a method (400) for providing heating control in a pilot coke oven (104), in accordance with an embodiment of the present disclosure. As explained above, the system (102) provides uniform heating control and temperature profile management in the PCO (104) during the heating and carbonization cycle. The method (400) starts at operation (402).
[0034] At operation (402), the method (400) includes transmitting, by a central control system (110), a pulse signal to a plurality of power controllers (108) based at least on temperature profile data.
[0035] At operation (404), the method (400) includes in response to the pulse signal, triggering the plurality of power controllers (108) to operate a plurality of heating elements (106a-106f) installed in one or more heating zones (Z1-Z6) of the pilot coke oven (104) based at least on a phase angle control. The phase angle control associated with the plurality of power controllers (108) adjusts a conduction angle of an alternate current (AC) signal of the plurality of power controllers (106a-106f). This results in control of a magnitude of an average AC voltage and AC current associated with the plurality of heating elements (106a-106f). Further, controlling the magnitude of average AC voltage and AC current enables the plurality of heating elements (106a-106f) to attain a set temperature at a set heating rate for providing uniform heating in each heating zone of the one or more heating zones (Z1-Z6) of the pilot coke oven (104) during heating and carbonization cycle.
[0036] At operation (406), the method (400) includes facilitating, by the central control system (110), display of at least a temperature of each heating zone (Z1-Z6), a magnitude of voltage, current, and resistance associated with the plurality of heating elements (106a-106f) in each heating zone (Z1-Z6), wall pressure and charge height on a human-machine interface (122) in real-time. Further, the one or more operations performed by the system (102) for providing uniform heating control and carbonization/temperature profile management, are explained with references to FIGS. 1 to 3A-3F, therefore they are not reiterated herein for the sake of brevity.

[0038] In another advantageous aspect of the present disclosure, center coke mass temperatures of coke is achieved at a faster rate (or with no delay) due to uniform heating of each heating zones. Further, due to the uniform heating of pilot coke oven, the quality of coke mass obtained from each heating zone is similar.
