Heat absorbed by water = 0.95 Vs(t 1 − t 2)MJ s −1,t 1 and t 2 = temperature of hot gases before and after the W.H. boiler, C. Total heat as steam = sensible heat in feed water + heat absorbed by water in boiler. In good practice t 2, the temperature at which the flue gases leave the boiler, may be reduced to ca.50 K above the temperature of the water in the boiler.

23/10/2018 · The rate of thermal energy transfer. A steady flow boiler takes in feed water at 1.5kg/s, at a temperature of 30 °C. The water is heated and turned into wet steam. This leaves at 1.5kg/s, with a pressure of 10 bar and a dryness fraction of 0.97 to the superheater, where it receives heat at a constant pressure and emerges at a temperature of

16/11/2019 · Steam generation is an essential process in steel production. Saturated steam is used in the cold-rolling mills of sample steel company to raise the acid pool temperature. The studied water-tube boiler had a rated saturated steam generation capacity of 47 tons per hour. This study used energy and exergy balance equations for each of the components in the cycle to calculate exergy efficiency
