Control of Nitrogen Oxides in Boiler Flue Gases by Two

It employs attemperation and flue gas recirculation for steam temperature control and uses 600 °F preheated air for combustion. Previously, it had been established that the nitric oxide concentration in the flue gas from the boiler during full load oil firing was approximately 685 ppm.f During the period from April 8 to July 10, 1957, a series

The smell of Gas from the boiler flue - JSL Heating Glasgow

Because it was a potential gas issue, we arrived as quickly as we could and began examining the boiler. The smell of gas is actually added in as a safety feature because gas itself is odourless. So what they were smelling was the unburnt chemical that was coming from the flue. This is actually fairly normal. However the smell was stronger than

The fuel's chemical potential energy is converted to heat energy via combustion inside the boiler. Heat is transferred to the water by thermal radiation from the flame and convection from the flue gas. In condensing boilers, energy in the water content of the flue gas can be utilized. Thereby a thermal efficiency close to 100 % is achievable.

1.4 Natural Gas Combustion

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

The flue gas is directed to a flue gas scrubber, in which the gas is cooled and water condensed. Any SO 2 present in the flue gas will be removed by means of a chemical reaction with sodium carbonate (soda ash). The soda ash is automatically added to the scrubbing water through pH control. After cooling and scrubbing, the gas is led via an
