In order to reduce the unit consumption of pulverizing system and power consumption of fan of ultra supercritical unit in thermal power plant

the operation mode of coal mill is optimized to reduce the 700 unit consumption of pulverizing system of MW unit

power consumption of fan

exhaust gas temperature and auxiliary power rate can save energy

reduce consumption and improve economic benefits. By comparing the parameters before and after optimization and using some data provided by electric power design institute

the annual economic benefit after optimization is calculated to be more than 2 million yuan. This test finally determines the optimal operation mode of coal pulverizer

that is to reduce the number of coal mills in reasonable load range as far as possible

which can be used as an effective reference for the optimization of pulverizing system of the same unit.
