Conversion of Existing Coal-Fired Boilers to Natural Gas

coal requiring 20% more pounds of coal could easily exceed the burning capacity of the stoker such that output of the steam generator may be reduced. In short, lower Btu coal will increase the pounds of coal to be handled and when the variations are large enough we can expect a reduction in boiler capacity. Higher Btu coal seldom gives any pro-

Jul 05, 2009 · Oil and gas fired units have more uniform sizes, but the coal fired units have large variation. High Ash Coals - A challenge to Power Plants - Optimisation of combustion in high ash coal fired boilers is of special interest due to the organic and inorganic mix up and the large amount of variation in the organics. One such experience with Indian low reactive coal in a tangential fired steam

Coal-Fired Boiler - an overview | ScienceDirect Topics

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).
