Smoke emission and control of fuel gas boiler - Ningbo

(inert) gas in LFG is equivalent to the inert gas entering a boiler when about six percent of the flue gas is recirculated to the boiler. Flue Gas Recirculation (FGR) is a widely applied technique for reducing nitrogen oxide (NOx) emissions from natural gas-fired industrial and commercial boilers, and boilers

What is Flue Gas? - Keison Products

Components of Flue Gas. The components of flue gas are listed below in the order of concentration in the gas. Nitrogen (N2) Nitrogen (N2) is the main component (79 vol.%) of the air we breathe. This colourless, odourless, tasteless gas plays no part in combustion. It is drawn into the boiler as ballast, heated and sent to the stack.

Natural Gas Fired Boilers

⇔ Airflow and flue gas flow is slightly lower or about the same. Natural gas boilers operate at lower excess air (O2) and a different airflow requirement for stoichiometric combustion. Coal fired boilers normally operate with 3-3.5% O2 (about 20% excess air). Whereas natural gas boilers normally operate at 1-1.5% O2 (about 7% excess air).

Exhaust gas - Wikipedia

Exhaust gas or flue gas is emitted as a result of the combustion of fuels such as natural gas, gasoline (petrol), diesel fuel, fuel oil, biodiesel blends, or coal.According to the type of engine, it is discharged into the atmosphere through an exhaust pipe, flue gas stack, or propelling nozzle.It often disperses downwind in a pattern called an exhaust plume.

GMAB™ Flue Gas Condensation - Babcock & Wilcox

Flue gas condensation By cooling the flue gas to below its dew point, it is possible to recover large quantities of latent heat. If the flue gas temperature after the boiler is approximately 150ºC it is possible by means of flue gas condensation, to increase the energy efficiency by an additional 20%.
