Power consumption of pulverized coal gasification coal mill
Thread Content
Dear seniors, there is a question that requires the expertise of those who are familiar with pulverized coal gasification. Regarding the power consumption of the coal grinder in this process: for raw coal with a basis moisture content of around 15%, an ash content of 15%, and a grindability index of approximately 55, what is the approximate power consumption per unit of coal ground by the grinder? I have been in contact with water-coal slurry before. For a mill operating at a concentration of around 60%, the power consumption is approximately 40 kilowatts per cubic meter of coal slurry. As for a mill capable of handling 60 tons of coal per batch, its power consumption is around 2800 KW. I tried to find some information on this topic, but couldn’t locate any approximate data regarding line mills used for gasification of pulverized coal; therefore, I would like to ask those who are more familiar with this subject for their insights
How do you calculate the power consumption of a water-coal slurry rod mill?
Try to find the actual coal consumption data for the coal mills in a previous project, and use the power consumption per unit of coal processed in that project as a basis to estimate the mill’s power consumption. However, the data available seems to be on the high side, with the power consumption per ton of coal reaching as much as 40 kW
