Flue Gas Waste Heat Boiler Thermal Efficiency Calculation

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 exhaust heat loss is the heat loss caused by a part of …

ANALYSIS OF FLUE GASES - Project Gutenberg

Flue Gas Analysis Calculations. Flue gases are formed on combustion of air with fuel in the presence of heat. Combustion of fuel release flue gases which is a mixture of Carbon Dioxide, Carbon Monoxide, Sulfur Dioxide, H 2 O Vapor, Nitrogen or Nitro-Oxides, Oxygen and ash particles. The quantity of flue gases is also calculated using stoichiometry calculation when air reacts with the fuel.
