Burner wear components for coal fired power plants | Engineer Live

21/2/2013 · All PFC fired units suffer wear, heat damage and slag in their burner systems due to the quality of the coal, choice of wear parts and the operating regime of the plant. Switching from stainless and mild steels to Ceraforte for burner system wear parts will significantly help maintain the original PFC distributions and the design efficiencies of the boiler thus minimising coal usage and downtimes.

KEY COMPONENTS OF BOILERS | Boilers Guide

Key Components of Boilers are:-. Burner – The burner is the component of boiler that provides the heat that heats the water of system. The fuels used can be natural gas or oil. Heat exchanger – The heat exchanger of boiler allows the heat from the burner to heat the water in system. The job of the heat exchanger is to carry the heat from

Coal-fired boilers are mainly operated at either subcritical or supercritical conditions. From a thermo-physics perspective, two phase mixtures of water and steam are replaced by a single supercritical fluid when the boiler pressure increases above the critical pressure of 22.12 MPa and the corresponding saturation temperature of 374 °C ( Shen and Cheng, 2004 ).
