Circulating Fluidized Bed Coal Boiler Distributed Control System Applications And The Bed Temperature Fuzzy Control

The Shandong Province Shengli oil field thick oil refinery two 75 ton fuel oils boilers begin work insufficiency, in order to effectively uses the state asset, the thick oil refinery and the victory power plant water coal tar factory and Shengli oil field power supply company three invest together more than 30 million Yuan, transforms two 75 ton fuel oils boilers 60 tons to burn the water coal tar circulation fluidized bed boiler.What this article studies is circulates the fluidized bed combustion system control plan. The circulation fluidized bed combustion system is a multivariable mutual coupling complex system, will effectively control the bed temperature is the boiler movement quality key. Formerly, circulated the fluidized bed boiler to use the measuring appliance control mode, caused the operator to be very difficult to adjust the boiler operating mode;Uses the Zhejiang University' s the control limited company' s SunyTDCS9200 lamination distributional integrated control system, obviously improved operator' s working strength, also causes the boiler safely stably to move.In this foundation, we taste the test fuzzy control mode temperature to carry on the automatic control to the bed, will affect the bed temperature factor to synthesize, held the primary factor, the fundamental research bed temperature has carried on the automatic control with the fuzzy control method , the practice proved the movement safer was reliable.
