Learn MoreHow to calculate boiler efficiency by Direct Method ? - ASKPOWERPLANT

Learn MoreA boiler or steam generator is a device used to create steam by applying heat energy to water.Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator.

Learn Morevalue of the coal is 33 MJ/kg. Feedwater from the economiser enters the boiler at a temperature of 90 °C. The boiler produces 5 000 kg of wet steam per hour and the steam is 0,95 dry. Calculate: 3.1 The quantity of heat absorbed by the feedwater in the economiser (4) 3.2 The thermal efficiency of the boiler (7)

Learn MoreNov 24, 2016 · Direct Method boiler efficiency. Parameters to be monitored for the calculation of boiler efficiency by direct method are : Quantity of steam generated per hour (Q) in kg/hr. Quantity of fuel used per hour (q) in kg/hr. The working pressure (in kg/cm 2 (g)) and superheat temperature (o C), if any; The temperature of feed water (o C)

Learn MoreIn this method, the efficiency can be obtained by substracting the heat loss fractions from 100. Boiler efficiency = 100 – (L 1 + L 2 + L 3 + L 4 + L 6 + L 7 + L 8). Where L 1 = Loss due to dry flue gas
