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).

2. BOILERS - Bureau of Energy Efficiency

The total air flow rate in a boiler changed with load demand, and the influence of different fuel types can be neglected at the same load level. On this basis, an air flow rate control strategy for coal-fired utility boilers was proposed and implemented in the boiler in which the air flow rate required to the furnace is a function of the unit load.

Evaporating this water uses a portion of the flue gas energy, thus, lowering boiler efficiency. This efficiency loss is offset somewhat by the lower amount of excess air required to burn natural gas. Boiler efficiency decreases are to be expected in the 3% to 4% range, depending on the current fuel and boiler …
