The invention discloses a coal blockage alarm device, a coal feeder, a coal feeder control system and a coal feeder control method, and relates to the technical field of coal burning. The technical problem that a coal blockage switch triggers a coal blockage signal by mistake is solved. The coal blockage alarm device comprises the coal blockage switch and at least one part of protective cover plates surrounding the coal blockage switch. The protective cover plates protect the coal blockage switch, and the coal blockage switch is used for outputting a coal blocking signal. The coal blockage alarm device is used for coal blockage alarm.
Description
technical field [0001] The present application relates to the technical field of coal combustion, and in particular to a coal blocking alarm device, a coal feeder, a coal feeder control system and a control method. Background technique [0002] The coal feeder is the main coal feeding equipment of the boiler pulverization system of the coal-fired thermal power plant. In the case of the coal feeder being blocked, the coal feeder equipment can generally be stopped to ensure the safe operation of the coal feeder equipment. [0003] The coal blocking switch is a coal blocking alarm device used to protect the safe operation of the coal feeder equipment. It is used to send a coal blocking signal when the coal feeding pipe of the coal feeder is blocked to stop the operation of the coal feeder equipment. [0004] However, in the related technology, due to special circumstances such as the impact of the coal flow on the coal blocking switch and the wet coal sticking to the coal block...
