Germany uses low heat (net calorific) value basis, implying that for an identical boiler, the stated efficiency will be higher. There are two methods of assessing boiler efficiency; 1. Input – output or direct method, and 2. Heat loss or indirect method.

Get a QuoteThis method calculates boiler efficiency by using the basic efficiency formula- η=(Energy output)/(Energy input) X 100 In order to calculate boiler efficiency by this method, we divide the total energy output of a boiler by total energy input given to the boiler, multiplied by hundred.

Get a QuoteFor high temperature flue gases it is common to use a steam boiler, commonly known as heat recovery steam generator (HRSG), to produce high pressure (usually >50 pounds per square inch gauge psig) steam and use this steam in a turbo generator to produce electrical power. In this case, the working fluid is

Get a QuoteThe 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.

Get a QuoteUSING BOILER FLUE TEMPERATURE TO CALCULATE IMPROVED BOILER EFFICIENCY DUE TO DESCALING Introduction A steam boiler with any amount of scale fouling (mineral deposits) on the boiler tubes will experience degradation in heat transfer and boiler efficiency.
