Condensing Economizer Description
1. The condensing economizer improves waste heat recovery by cooling the flue gas below its dew point, which is about 135°F for products of combustion of natural gas.
2. The economizer reclaims both sensible heat from the flue gas and latent heat by condensing flue gas water vapor . All hydrocarbon fuels release significant quantities of water vapor as a combustion byproduct.
3. The equation below shows the reactants and combustion products for the stoichiometric combustion in air of methane (CH4), the primary constituent of natural gas. When one molecule of methane is burned, it produces two molecules of water vapor.
4. When moles are converted to pound/mole, we find that every pound of methane fuel combusted produces 2.25 lb. of water vapor, which is about 12%of the total exhaust by weight.
