Inert gas - Wikipedia

The flue gas system uses the boiler exhaust as its source, so it is important that the fuel/air ratio in the boiler burners is properly regulated to ensure that high quality inert gases are produced. Too much air would result in an oxygen content exceeding 5%, and too much fuel oil would result in carryover of dangerous hydrocarbon gas.

1.4 Natural Gas Combustion - US EPA

from natural gas-fired boilers are flue gas recirculation (FGR) and low NOx burners. In an FGR system, a portion of the flue gas is recycled from the stack to the burner windbox. Upon entering the windbox, the recirculated gas is mixed with combustion air prior to being fed to the burner. The recycled flue gas

15 Ways to Increase Boiler Efficiency in Your Facility

Jul 30, 2020 · Think about it; the boiler draws in cool air, heats it up, and sends it out the stack. A lower stack gas temperature is ideal because the higher the temperature, the more energy leaves with the flue gas. On the other hand, the boiler system takes in cold water, heats it to steam, and uses the heat.

Dec 15, 2020 · For example, through exhaust gas recycling, in which flue gas from natural gas boiler (containing ∼4% Co2) is recycled and used in place of air for the fuel combustion, Co2 concentration in the flue gas can be enriched up to ∼8%, making Co2 capture less thermodynamically challenging (Vaccarelli et al., 2014).

Apr 04, 2018 · When using flue gas from a main or auxiliary boiler, an oxygen level of less than 5% can generally be obtained, depending on the quality of combustion control and the load on the boiler. When an independent IG generator or a gas turbine plant with afterburner is fitted, the oxygen content can be automatically controlled within finer limits

Incineration - Wikipedia

Incineration is a waste treatment process that involves the combustion of organic substances contained in waste materials. Industrial plants for waste incineration are commonly referred to as waste-to-energy facilities. Incineration and other high-temperature waste treatment systems are described as "thermal treatment".Incineration of waste materials converts the waste into ash, flue gas and heat.

Boiler Efficiency - an overview | ScienceDirect Topics

The flue gas loss depends on the final flue gas temperature and the amount of flue gases. Thus the higher the air ratio, the higher the flue gas losses. The flue gases should leave the boiler at a temperature as low as possible to minimize the flue gas losses. Usually either economics, equipment, or corrosion issues limit the flue gas to 150
