DHX coal-fired CFB (circulating fluidized bed) steam

2020-11-18 · As a new mature high-efficiency and low-pollution clean coal technology, circulating fluidized bed combustion (CFBC) technology has many advantages that other combustion methods do not have. Circulating fluidized bed combustion is low-temperature combustion, so the NOx emission is much lower than that of pulverized coal furnace, only 200ppm.

Boiler (power generation) - Wikipedia

2  · A boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

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).

Calculating Power Plant Coal Consumption--ZBG -

2020-8-25 · Second part is the steam cycle efficiency. Modern Rankine cycle, adopted in coal fired power plants, have efficiencies that vary from 32 % to 42 %. This depends mainly on the steam parameters. Higher steam pressure and temperatures in the range of 600 ° C and 230 bar have efficiencies around 42 %. We assume a value of 38 % for our case.
