Abstract

The invention provides a fuzzy control method and a system for the automatic combustion of an incinerator. The fuzzy control method for the automatic combustion of the incinerator comprises the steps of receiving a detection input variable sent by a detection device, calculating the deviation and the deviation change rate between the detection input variable and a given value, and adopting the deviation change rate as the input variable of the fuzzy control; fuzzifying the input variable as a fuzzy input variable, conducting the fuzzy reasoning and the fuzzy decision-making based on the fuzzy input variable to obtain a fuzzy output variable, and defuzzifying the fuzzy output variable to be as a control output variable; outputting the control output variable to a controller for the corresponding component of the incinerator so as to control the operation of the corresponding component of the incinerator. The detection input variable includes the oxygen content at the outlet of a boiler and the load of the boiler. The control output variable, corresponding to the oxygen content at the outlet of the boiler, contains the given data of the primary air flow. The control output variable, corresponding to the load of the boiler, contains an infrared temperature given value and a feeding speed value. Based on the above method and the above system, the complex control problems of multiple variables and large time delay during the waste incineration process can be solved.

Description

technical field [0001] The invention relates to the incineration of garbage and other wastes, in particular to an automatic combustion fuzzy control method and system for an incinerator. Background technique [0002] my country's economic development and urbanization process have led to a substantial increase in the amount of urban domestic waste. Waste incineration power generation is an effective way to make waste harmless, reduce, and recycle waste. Waste incineration treatment can not only achieve environmental protection effects, but also waste heat from waste incineration It can generate steam for power generation, heat supply, energy saving, and it is a better resource recycling method. [0003] In the automatic control of waste incineration, the quality of the combustion control of the incinerator directly affects the operation status and steam output of the incinerator, which in turn affects the environmental protection emission indicators and the power generation of...
