Get A QuoteThere are two methods for boiler efficiency calculation:-Direct Method. Indirect Method. Direct method: Direct method is quick method for boiler efficiency calculation, In this method, Percentage of total heat output vs heat input is calculated to establish boiler performance. Boiler Efficiency = Heat output / Heat Input X 100. Or Boiler Efficiency = Q X (h2 – h1) / (q X GCV) X 100

Get A QuoteIndirect method Indirect method determines the efficiency of a boiler by the sum of the major losses and by the fuel power of the boiler: φlosses η =1− (15) φinput where φ losses is the sum of the major losses within the boiler, and φ input is the fuel power of the boiler. The indirect method provides a better understanding of the effect

Get A Quoteefficiency. Boiler efficiency, in the simplest terms, represents the difference between energy input and energy output. A typical boiler will consume many times the initial capital expense in fuel usage annually. Consequently, a difference of just a few percentage points in boiler efficiency between units will result in substantial fuel savings.
