• ### Factors affecting Boiler Efficiency in Thermal Power Plant

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

• ### Combustion Efficiency and Excess Air

The improvement in boiler efficiency can be determined by measuring the stack flue gas temperature. The stack gas temperature should decrease when the turbulators are installed. As a rule of thumb, a 2.5% increase in the boiler efficiency is expected for each 50°C (90°F) decrease in the stack flue gas temperature. •

• ### Boiler Efficiency & Combustion Efficiency

The flue gas temperature across a firing range will vary from boiler to boiler. A true three pass design will generally have lower flue gas temperatures and a greater heat transfer surface. Boiler insulation will also have an impact on radiated losses. The factors affecting combustion efficiency are …
