Directing against singleloop system for regulating pressure in the furnace

through consulting control strategy of several 600 MW coalfiring powergenerating units at home and abroad

a singnal processing model for circuit measuring presure in the furnace has been put forward. The method for pressuremeasuring signal acquisition and processing for minimizing system fluctuation has been analyted and studied in detail

the advantages and resonableness of the said processing model being verified by using simulation method. The abovementioned method has already been successfully used in pressure control system for furnace of 600 MW unit at Hanfeng power plant.
