WEBJul 26, 2021 · The pulverized coal processed by the CLIRIK coal mill is fully burned and has a high utilization rate. It has provided technical support for dozens of power plants. When the humidity of the raw coal is below 15%, the CLIRIK coal pulverizer is used to grind the raw coal into 200 meshes.
WEBThe fineness of the milling product and the capacity of the pulverizer are strictly connected. With increased fineness grows the overall circulation rate of coal in the mill, coal retention time and the flow resistance. As a result, the maximum mill capacity decreases and the rate of change of operational parameters of the furnace system ...
WEBNov 25, 2020 · A forced draft fan motor current (FFC) was used during boiler combustion to regulate the air flow rate entering the furnace. The results show that the FFC and coal flow change with the power output. However, the coal flow exhibits larger fluctuations than the FFC, indiing that the air/coal ratio is out of balance at certain times.
