Abstract


Based on the gas furnace production process of research, analysis of various process parameters on the efficiency of gasification and gas production systems Shaoye the main problem, a distributed control system's overall control scheme. Thesis based on expert system theory, design expert coordinator , based on the total load and status information for each stage furnace , the furnace of the pressure obtained optimal settings to ensure that each furnace run equilibrium . Furnace pressure controller using the WAS control algorithm , not only simple and convenient, and can reduce the number of valve action , to ensure regulation accuracy. Saturation temperature of the gas not only affects the yield, quality and process stability, and working life and the furnace has a close relationship . Saturation temperature control using the conventional PID control to adjust the valve opening degree of the steam , but only by the saturation temperature of the valve opening degree , but also by the vapor pressure within the drum , the amount of the blast . In this paper, fuzzy control, in order for this non-linear and strong coupling objects. Actual results indicate that fuzzy control is better than PID control. Based on the functional requirements of the system to determine the overall system architecture and hardware configuration , software application developed to achieve the function of the system . Distributed Control System gas furnace furnace conditions through centralized monitoring to ensure the stability of the key parameters to optimize the gasification conditions , thus improving the gas furnace operating conditions , reduce labor intensity , in order to create a good economic and social benefits .
