· Mills that have coalfired power onsite could be forced to make significant overhauls if the rules are finalized. "For some plants, the capital requirements (of the EPA rule) will deplete multiple years of discretionary capital and include a continued operating cost that often equates to 5 to 10 percent of payroll," said Expera spokesperson Addie Teeters.

What is boiler? It is an enclosed pressure vessel in which water is converted into steam by gaining heat from any source (coal, oil, gas etc). Boiler in thermal power plant accumulates the steam and build up a pressure to expend it in turbine and convert thermal energy to mechanical energy. The generator which is connected to turbine converts the mechanical energy into electric energy.

11/11/2009 · Pulverizing mills in boiler plants play a major role in preparing the coal for firing in a boiler. Coal, being a heterogeneous fuel, varies in its properties; the variation depends on many factors like type of origin of coal, formation, major parameters which decide the mill capacity and performance are the hardness of the coal and the total moisture level in coal.
