Analyzing of Compensating of Quality in Mine Gate

Combustion control of thermal power plants is multi-input, multi-output, uncertain complex system. It is important that characteristic of system can be mastered to control combustion reliably and economically. So it is one of the effective means that using the dynamic characteristic of air fuel ratio obtains stable combustion. In the paper that state of fuel feed can be estimated based on fuzzy rule and measure by means of fuzzy inference machine in boiler running. Combustion of boiler is the best economical and safe at 5 times through engineer groping long-time experience, the instance illustrate that the methodological is validity and stability.
