PLC BASED DATA ACQUISITION AND CONTROL SYSTEM FOR ON-LINE GAS PRESSURE AND DRAUGHT CONTROL IN COKE OVEN BATTERY.

摘要

An arrangement for online control of coke oven battery heating gas pressure and battery draught involving both feed back and feed forward strategy comprising Programmable and Logic Controller (PLC) (6) based data acquisition system adapted to receive signals of parameters selected from Coke Mass Temperature; Goose-neck temperature (8); Coking Index; Heating gas; Calorific value; Coal Moisture; Heating Gas Flow; Heating Gas Pressure; Battery Draught; Tunnel Temperature; Winch reversal and comprising means (9) for storage and display of the data thus acquired; and means for communicating with the control system (7) of the arrangement; and a control system (7) adapted to receive inputs from the PLC and predict heating gas pressure and battery draught values comprising means for processing heat demand values given by the equation.
