Flue Gas Waste Heat Boiler Thermal Efficiency Calculation
Determining & Testing Boiler Efficiency for Commercial
The principal nitrogen pollutants generated by boilers are nitric oxide (NO) and nitrogen dioxide (NO2), collectively referred to as NOx. The contribution from different NOx sources to the total NOx levels varies among metropolitan areas.

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 the heat that is taken away by the smoke of the boiler.
unit. If you are evaluating a boiler where the stated efficiencies are higher than the theoretical efficiency value, watch out! The efficiency value you are utilizing may not truly represent the fuel usage of the unit. In the end, efficiency comes down to properly testing the performance of the boiler and the performanceof the burner.
Boiler Heat Balance: The heat balance sheet for boiler can be prepared as: Boiler Trial: Objective of a Boiler Trial: (a) To estimate steam raising capacity of the boiler when working at a definite pressure (b) To determine the thermal efficiency of the boiler when working at a definite pressure (c) To draw up a heat balance sheet for the boiler.
