Coal Fired Power Plants Intelligent sootblowing closed-loop control method, apparatus and system for

The present invention discloses one kind of coal-fired utility boilers sootblowing smart loop control method, apparatus and system. Wherein according to the real-time collection of field data, determining factor heating surface cleaning, and time integration factors corresponding complement factors, and are converted into fuzzy theory domain quantization levels, the quantization level of the cleaning factor, factor quantization level time integration and supplementary soot blowing factor fuzzy control model input quantization level set in advance, for the fuzzy control soot blowing model solver, to obtain the corresponding confidence sootblowing, the sootblowing command generated according to a corresponding confidence sootblowing and plant conditions, the sootblowing command sent to the PLC controller, PLC controller for soot-blowing operation in accordance with the corresponding instruction sootblowing. By considering the factors affecting the operation of the closed-loop control of the soot blowing soot blowing system, guaranteed in the case of heat transfer characteristics of the heating surface, to minimize soot blowing frequency, to achieve energy saving and improve the economics of plant operation and safety purpose.
