The heat in the steam produced is about 95% of that lost by the gases passing through the boiler. Heat lost by hot gases = V s ( t 1 − t 2) MJs − 1, where V = m 3 gas/sec, s = specific heat (volume basis). Heat absorbed by water = 0.95 Vs ( t1 − t2 )MJ s −1, t1 and t2 = temperature of …

The heat from the burner is transferred to the water tubes. As water flows through the tubes, the combustion gases heat the water and produce steam. This steam is collected in the upper drum, while combustion gases exit the boiler stack as flue gas. Several types of tubes are found inside the boiler.
