The invention discloses a coal mill primary air pressure control method and device, a storage medium and electronic equipment, and relates to the technical field of coal-fired power generation. According to the specific implementation scheme, in response to a received power generator load increasing instruction, a target load value is obtained, based on preset pressure control data, a first primary air pressure value corresponding to the target load value is determined, and according to the first primary air pressure value, the pressure of primary air in a primary air mother pipe of the coal mill is adjusted; and in response to the fact that the power generation load value of the current generator reaches the target load value, a second primary air pressure value corresponding to the target load value is determined based on preset pressure control data, and the pressure of the primary air in the primary air mother pipe is adjusted according to the second primary air pressure value. The throttling loss of the primary air mother pipe of the coal mill is effectively reduced while the load rising response speed is guaranteed.
Description
technical field [0001] The present application relates to the technical field of coal-fired power generation, and in particular, to a method, device, storage medium and electronic device for controlling primary air pressure of a coal mill. Background technique [0002] In the related art, in order to improve the load response speed of the load-raising process of the power plant boiler using the direct-blown pulverizing system, it is necessary to increase the pressure value of the primary air main pipe at the inlet of the coal mill. When the opening of the hot air baffle in the pipe continues to increase, the primary air volume has a flow response to meet the load response speed. When the set value of the primary air main pipe pressure is high, the hot air door baffle of the coal mill is under excessive pressure, resulting in the opening angle of the hot air door baffle being smaller than the set angle, and there is a throttling loss. SUMMARY OF THE INVENTION [0003] The ...
