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.

The MRS® (Magaldi Mill Rejects System) is a new process concept designed to mechanically handle rejects from coal mills, in a dry way. Rejects are a mixture of different materials (pyrites, stones, tramp iron, etc.) with pulverized coal, requiring a reliable and safe removal system.
Clinker formation is a serious problem in boilers of thermal power plants which results in forced outage and generation loss. Removal of clinkers from the water wall is difficult thus requires pneumatic hammering. Low quality coal having less gross calorific value, high mineral content, high ash content, and the over-firing of molten slag are causes of clinker formation.
The main two losses in boiler that can be tuned by operator are carbon loss and dry gas loss. There are a few minor losses in boiler which can also be optimized like the mill reject loss and the carbon monoxide loss. Pulverized coal fired boilers the total losses account to about 12 to 14 %. Roughly 50% of the losses can be tuned to the optimum ...
