itself to changing process situations like e. g. changes in coal qualities, mill wear, wall slagging, soot blowing etc. ensures compliance with the limit values for NO x and ammonia slip in all load cases (10 percent 100 percent). The combination of primary NO x reduction with advanced combustion optimization plus OnlineCFD as
This is all controlled by the coal mill or pulveriser, and its associated feeder equipment. Operation of the coal mill can affect the ramp rate of the power station and its ability to handle rapid changes in output. For coalfired power plants, the response time of the coal mills is critical for the overall reaction time to changing demand.
