Problems solved by technology
[0003] At present, the research on the supercritical circulating fluidized bed boiler body is not yet mature, and the research on the control system is also in the exploratory stage, but the unit's commercial operation means that the load change must be stable and meet the requirements of the power grid, and because this boiler is a circulating fluidized bed Combined with supercritical DC independent design for the first time, without mature control system research experience
Especially in terms of air intake control, there is no relatively mature automatic control system

Description
technical field [0001] The invention relates to a boiler air intake control system, in particular to a coal power boiler air intake control system. Background technique [0002] With the development of circulating fluidized bed technology, large capacity and high parameter circulating fluidized bed boiler has become one of the main technologies for energy saving and consumption reduction. Both circulating fluidized bed and supercritical are mature technologies, and the combination of the two is relatively less risky. The combined technology combines the advantages of low-cost pollutant control of circulating fluidized bed boilers and high-efficiency power supply of supercritical boilers. , material cost, and manufacturing level have great commercial potential and obvious advantages of coal-fired power generation technology. The circulating fluidized bed boiler is a supercritical once-through boiler, which adopts double air-distribution panels and single furnace, H-shaped la...
