Heat recovery — HeatCalc

The name of the game is surface area. There are numerous varieties of heat exchanger and boiler designs, but all aim to increase the surface area exposed to the flue gas. The more surface area, the more heat transfer. Tubes are the most common application, with the flue gas inside the tube and the water around it, or vice versa.

flue gas heat recovery - CSE

The heat efficiency of a flue gas waste heat boiler is the percentage of the effective heat in the heat injected into the fuel. The anti-balance test method is usually used to measure boiler thermal efficiency. The calculation formula for the thermal efficiency of the anti balance method: η= 100- (q2+q3+q4+q5+q6) 1. q2-flue gas heat loss

The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel. You can also refer to Thermodyne's Boiler Bible that provides you the general composition of above elements for various fuels. The calculator below helps you determine the amount of flue gases generated per Kg of fuel by providing the elemental composition of fuel and its mass faction.
