Waste Heat Boiler - an overview | ScienceDirect Topics

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.
