what are boiler efficiency and boiler evaporation ratio
WebFeb 28, 2024 · IS 8753: Indian Standard for Boiler Efficiency Testing. How is boiler evaporation rate calculated? The boiler evaporation ratio is expressed as follows: Evaporation ratio = quantity of steam generation/quantity of fuel consumed. For example quantity of steam Is 310 ton/hr and fuel is 55 ton/hr then the evaporation ratio is 5.63. WebBasing the calculations on an average evaporation rate of 10000 kg/h, for a plant in operation 8 400 h /year, the energy required to replace the heat in the make-up water is: 10 000 kg/h x 335 kJ/kg x 8 400 h/year = 28 140 GJ/year. If the average boiler efficiency is 85%, the energy supplied to heat the make-up water is: pip questions for mental health
