Flame Safeguard Controls - Fireye

2018-4-4 · A flame is a zone within which the combus-tion reaction occurs at a rate that produces visi-ble radiation. A flame front is the contour along which the combustion starts — the dividing line between the fuel-air mixture and the combus-tion process. In stable flames, the flame front appears to be stationary. The flame moves

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).
