Boiler Factor Of Evaporation And Equivalent


In a boiler trial observations made are as: Calculate the …A boiler generates 7.5 kg of steam per kg of coal burnt at a pressure of 11 bar. The feed water temperature is 70°C; boiler efficiency is 75%; factor of evaporation is 1.15; C p = 2.1 kJ/kgK. Calculate: equivalent evaporation in kg of steam perBoiler Factor Of Evaporation And Equivalent - Edge HouseFactors Of Evaporation Example.-Suppose that a cylinder boiler is to be proportioned for an evaporation of 500 lbs. of water per hour, at a pressure of 75 lbs., the temperature of the feed-water being 80°. The equivalent evaporation will be 1.17 times 500, or 585 lbs., and the grate-surface 585 divided by 75, or 7-8/10 square feet.

Steam - water, pound, heat, boiler and temperatureSTEAM Factor of Evaporation. The factor of evaporation for any given feed water temperature and boiler pressure is calculated by dividing the total heat above F. in one pound of steam at the given pressure minus the total heat in one pound of the feed water above F. by the latent heat of steam at F., which is 970.4 British Thermal Units.120050593 Boiler Calculation - Sistemas TérmicosDetermine (a) the equivalent evaporation per ton of coal fred (b) the eff,rciencY of the boiler (c) the overall efficiency of the boiler Solution Step (I) Heat l-oad of Steam/Ton inrhalpy of dry, saturated steam at 60 kgflcm2 abs. :665.4 kcaVkg Enthalpy of water at 120"C
