direct method for boiler efficiency


way boiler efficiency by indirect method is more useful …Boiler Efficiency Boiler efficiency includes the calculation of sensible heat losses (in boiler flue gases and ash), which are dependent on coal composition, excess air levels and temperatures at boiler inlet and airheater outlet. From: The Coal Handbook: Towards Cleaner Production: Coal Utilisation, 2013direct method of boiler efficiency calculationDirect 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 Where Q = Qty of steam generated.

Direct Method boiler efficiency lecture notesDirect Efficiency. In the direct method, efficiency is calculated by dividing energy delivered by the boiler by energy input as fuel, using the equation: % Efficiency = F (hs - hw) / NCV X f. where F = Steam generation in Kg/hr. hs = enthalpy of steam at operatin pressure …Energy Performance Assessment of CFBC BoilerDirect Method and Indirect Method for Boiler Efficiency Thermal efficiency % of (heat) energy input that is effectively useful in the generated steam BOILER EFFICE CALCULATION 1)DIRECT METHOD: 2) INDIRECT METHOD: The energy gain of the the efficiency is the working fluid (water and steam) different between losses is compared with the energy and energy input 25 content of the boiler fuel.
