The Optimization to Control System of Desulfurization in Furnace of 300MW CFB Boiler

摘要

This paper contraposes 300MW CFB boiler of Shanxi certain coal-fired power plant, then optimize the control system of desulfurization and remake limestone transmission system. Collect signal to establish knowledge base for judging starting or stalling control of feeding machine lots of experiments. Adopt feedback control strategy to adjust the speed of feeding machine. Achieve the purpose of automatically controling the starting or stalling of feeding machine and the speed of feeding machine finally.
