Jan 06, 2010 · The flue-gas temperature of a typical boiler could be anywhere in the range of 300 to 500 degrees Fahrenheit range. As a result, the extra oxygen could have entered the boiler at 70 degrees F and exit at 400 F. The extra oxygen reached this temperature by receiving fuel energy – in other words, fuel was purchased to heat the extra oxygen.

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 ).

Jun 15, 1994 · Normal operating temperature in the combustion zone is approximately 2,000 - 3,000 degF. The boiler produces 4,500,000 lb/hr of steam for a General Electric steam turbine generator rated at 688 MWe. Figure 2-1 is a diagram of the process. Combustion air is supplied from two sources, the primary and secondary air systems.
