Typical Causes of Slagging and Fouling Problems in Boilers

Jun 01, 2015 · Consequently, the sweet spot for the FEGT of a pulverized coalfueled boiler should be about 2,150F to 2,250F to achieve desired steam temperatures without slagging. Lower than 2,150F

Coal-fired power station - Wikipedia

In a coal-fired power plant, the boilers generate thermal energy by burning pulverized coal. Accurate temperature control is very important to maintain a safe and stable process. Two Pt100 sensors are used to make a redundant temperature measurement. To maintain a stable, reliable process, it is important that the maintenance engineer is notified in case of a primary sensor failure, while the secondary

Boiler In Thermal Power Plant - Coal Handling Plants

Jan 15, 2019 · How does a steam boiler work? In pulverized coal fired boiler,The coal is pulverized to a fine powder, so that less than 2 % is +300 micro meter and 70 75 % is below 75 microns. The pulverized coal is blown with part of the combustion air into boiler plant through a series of burner nozzles. Combustion takes place at temperature from 1300 1700 °C, depending largely on coal grade.
