Experimental study of natural gas temperature effects on

The flame radiation enhancement in gas-fired furnaces significantly improves the thermal efficiency without significantly affecting the NO x emissions . In this paper, the effects of inlet natural gas preheating on the flame luminosity, overall boiler efficiency, and NO emission in a 120 kWboiler have been investigated experimentally.

Hydrogen: The Burning Question - Features - The Chemical

Sep 23, 2019 · The flame which one hopes never to see in a furnace is a detonation flame. The heat of combustion from a flame at the centre of a pre-mixed cloud of gas and air produces a pressure wave which is sufficient to provide the source of ignition to the adjacent mixture (like a diesel engine) and so the combustion front proceeds at the speed of sound, or greater.

WHAT TO EXPECT WHEN NATURAL GAS IS FIRED IN A COAL-FIRED BOILER ⇧ Furnace exit gas temperature (FEGT) is likely to increase. Natural gas firing flame emissivity is lower than that for coal. This means the furnace water wall absorption is typically lower with natural gas firing. The amount of heat absorbed by the water walls regulates FEGT.

Flame Safeguard Controls - Fireye

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 …

Coal-Fired Boiler - an overview | ScienceDirect Topics

H. Widell, in Biomass Combustion Science, Technology and Engineering, 2013 Furnace design. Just as coal-fired boilers are not designed in the same way as oil- or gas-fired boilers, neither can biomass-fired boilers be designed as coal-fired boilers, if they are to function efficiently. Biomass firing requires a larger furnace (i.e. a larger radiation heat transfer surface) than coal firing.
