Investigation of mercury release from lignite in power plant mills. At two power plants, lignite samples (Lignite A and Lignite B) were taken simultaneously at the feeder before entering the coal mill and from the dust line after the coal mill. Afterwards, the raw lignite and the ground lignite were analyzed for mercury concentration.

Introduction. Steam cycles have been used for electric power generation from coal since the early 1900's. These first coalfired power units featured outputs in the range 110 MW and the steam generator already included an economizer, an evaporator, and a superheater (Harvey et al., 2020).According to the same reference, the first steam cycle had an efficiency of only % while those ...

Coal mills consume a huge amount of station service electricity power of a coalfired power plant. Meanwhile, the operation of coal mills also has a large influence on boiler combustion. Among all the operating factors, the electricity current intensity of coal mills reflects the electricity power consumption as well as operating status of coal mills. If the electricity current intensity of ...
