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).

Flue Gas - an overview | ScienceDirect Topics

The flue gas exits the cyclones to a plenum chamber in the top of the regenerator. The hot flue gas holds an appreciable amount of energy. Various heat recovery schemes are used to recover this energy. In some units, the flue gas is sent to a CO boiler where both the sensible and combustible heat is used to generate high-pressure steam.

Flue Gas Temperature and Heat in the Flue Gas Flow (Btu/hour) [ back to full computer program list] This computer program calculates the specific heat (Btu/lb-F) and the enthalpy (Btu/lb) for typical gases found in the flue gas of combustion systems.

Fired Boiler - an overview | ScienceDirect Topics

More recently oxy-natural gas and oxy-coal firing were tested in an existing 15 MWt industrial packaged boiler with and without flue gas recirculation. 5, 6 The boiler was designed to produce up to 60,000 lb/h with mild superheat (135 pisg, 454 °F). Local heat flux to a boiler tube in the side wall about 30 inches from the burner wall was

ANALYSIS OF FLUE GASES - Project Gutenberg

2007-9-18 · Determine: The flue gas analysis by weight (see Table 33), the amount of air required for perfect combustion, the actual weight of air per pound of fuel, the weight of flue gas per pound of coal, the heat lost in the chimney gases if the temperature of these is 500 degrees Fahrenheit, and the ratio of the air supplied to that theoretically
