Abstract

The present invention belongs to the technical field of thermal power generation, in particular to a pulverized coal additive device dedicated to thermal power generation equipment. Aiming at the existing adding method, the distribution of the additive is not uniform enough to fully contact with the pulverized coal, resulting in the additive not being able to fully react at the first time. , the problem of relatively low utilization rate, the following scheme is proposed now, which includes a special coal powder additive device for thermal power generation equipment, including an air compressor, a mixing chamber and a furnace body, and the output end of the air compressor is fixedly connected with a A gas pipeline, the gas pipeline extends to the mixing chamber, the furnace body is fixedly connected with a heat shield, and the heat shield is rotatably connected with a connecting pipe. The invention drives the output shaft to rotate by starting the driving motor, and drives the adding pipe to rotate, so that the additive blown out from the through hole is more evenly distributed into the furnace body, fully contacted with coal powder, and the utilization efficiency of the additive is improved.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a special coal powder additive device for thermal power generation equipment. Background technique [0002] Thermal power generation is a power generation method that uses the heat energy generated by combustibles during combustion and converts it into electrical energy through a power generation device. China is rich in coal resources, and there is still a huge potential for thermal power generation. According to its function, thermal power generation can be divided into power supply and heat generation. According to the prime mover, it can be divided into steam turbine power generation, gas turbine power generation and diesel engine power generation. According to the fuel used, there are mainly coal-fired power generation, oil-fired power generation, and gas-fired power generation. In order to improve comprehensive economic benefits, thermal power generation ...
