Abstract

The invention relates to an automatic control method for a burner type industrial boiler and a device for the automatic control method, and belongs to the field of boilers. A heat carrier temperature parameter, a furnace box temperature parameter, a furnace box negative pressure parameter, a furnace box flue gas component content parameter, a heat carrier flow parameter and a heat carrier pressure parameter are subjected to software analysis and expert database reasoning operation, the optimal data of a fuel supply amount, a combustion air amount and the furnace box negative pressure is determined in real time, the opening of a fuel supply regulating valve and a nozzle of a burner, the opening of a combustion air regulating valve, and the rotating speed of an induced draft fan motor are controlled in real time, and the fuel supply amount, the combustion air amount and the furnace box negative pressure are controlled in real time. The system can accurately control the fuel supply amount, the combustion air amount and the furnace box negative pressure in real time, accurately controls the output heat carrier temperature, saves fuel and electric energy, and fulfills the aims of saving energy, reducing emission and reducing consumption.

Description

technical field [0001] The invention relates to the field of boilers, in particular to an automatic control method and device for a burner type industrial boiler. Background technique [0002] As we all know, industrial boilers are important equipment for providing heat energy required for production. The heat carrier is heated by fuel combustion, and the heat carrier at a certain temperature is transported to the heat-using equipment in the pipeline to meet the needs of industrial production. Improving the combustion efficiency of industrial boilers while accurately controlling the heating temperature of the heat carrier in real time is of great significance to the energy saving, consumption reduction, and emission reduction of industrial production and industrial boilers. [0003] Common movable grate industrial boilers use coal as the main fuel. Driven by the motor, the movable grate slowly transports the fuel into the furnace for combustion. The combustion air in the fu...
