Abstract

In order to improve the level of automatic control on a coal mill, the invention adopts a novel neural network control method for a direct-fired coal mill, so that the coordinated operation of the coal mill and a boiler can be carried out and the operation of the coal mill can be economical and efficient.

Description

technical field [0001] Industrial control, automation, coal mill, thermal power plant, pulverizing system Background technique [0002] The process of a thermal power plant is: the fuel is burned in the boiler, the water in the boiler is heated to turn it into steam, the steam turbine receives the steam supplied by the boiler, and its rotor is driven by the steam to drive the generator to rotate to generate electricity. In my country, most The boilers used in thermal power plants are pulverized coal boilers. The combustion process is that the pulverized coal is injected into the furnace together with the air for suspension combustion. In the pulverized coal furnace, the contact area between fuel and air is greatly increased, the combustion is more violent, and the temperature in the furnace is also higher, so the combustion efficiency is also higher. Therefore, the pulverized coal furnace must be equipped with a complete pulverizing system for grinding raw coal into pulveri...
