excess air. Station service power will decrease with drier coal due to a decrease in fan power and mill power. The combination of all these effects caused by firing drier coal will result in an improvement in boiler efficiency and unit heat rate, primarily due to the lower stack loss and lower station service power.

The power consumed by the mill per ton of coal ground is only two-thirds of the ball mills. However if the primary air fan power is also taken into account, in the case of a pressurized mill the power consumption is lower only by about 15%.

But for the independent solar thermal power generation system, both the high initial investment and lower thermal performance are major obstacles to its development 10.
