Flue gas and air leakages
WebAs the temperature of the flue gas increases, the temperature difference between the flue gas and the condensed water increases, the heat exchange is enhanced, and more water vapor in the flue gas condenses into water and is recycled, so the amount of water recycling increases and the recovery rate increases. WebJun 29, 2024 · If there is insufficient air (below the stoichiometric requirement, or fuel-rich combustion), unburned fuel goes out the stack. This wastes fuel, creates emissions and hazardous air pollutants. It also creates a potential safety issue should enough fuel subsequently mix with O 2 and ignite.

WebDec 1, 2006 · At the same time, leakages require more air to be transported to the preheater and more flue gas to be transferred from the preheater, and larger quantities of gases require more power for the air and flue-gas fans. These fans typically use up to 1.5% of all the power produced.

Webfrom 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 According to the U.S. Department of Energy, a single 1/8” (3mm) leak in a compressed air line can cost upwards of $2,500 a year.
