Nov 30, 2004 · For gas volume purposes, since equal moles of gas produce equal volume, the volume of exhaust gas replacing oxygen will be equal to 17/12.5 = 1.36. The volume percentage of oxygen in air is about 21% (not exact, but work with me here). This volume will be removed, and replaced by exhaust gas with a "volume" of (21*1.36) = 28.56%.

Free Chat### How to calculate heat of exhaust gases from a gas engine

The exhaust heat loss is the heat loss caused by a part of the heat that is taken away by the smoke of the boiler. Its size is related to the amount of smoke, the smoke exhaust and the reference temperature and the sensible heat of the water vapor in the flue gas. q2 can be used as a simplified calculation formula: q2 = (3.55αpy +0.44) (tpy-t0) / 100 In the formula, αpy - exhaust air excess coefficient

Free Chat### Application and Benefit Calculation of Waste Heat Recovery

In the boiler combustion of power plants, the smoke loss is the main combustion heat loss of the boiler. Reducing the exhaust gas temperature is one of the main means to reduce the heat loss of the exhaust gas, and it is also the main measure for improving the thermal efficiency of the boiler in each power plant. This paper summarizes and discusses the application and economics of installing
