Oct 12, 2017· The simulation calculations reveal that the 225 MW power unit can operate between 40 and load with reasonable efficiency. Power unit operation with reduced minimum load allows decreasing startup and shutdown operation costs. Reducing the minimum load of conventional coalfired power plants strongly influences operation of the steam turbine.
The reasons for coal hangup to mills can be many, like large raw coal size, jamming of the feeder, jamming of the coal chute from the bunker due to high moisture in the coal, foreign material at raw coal inlet to feeder, etc. Plant responses. The boiler fuel input coming down due to coal flow hangup the mill slowly gets unloaded.
