Waste heat recovery technologies and applications - …

1/6/2018 · The open combustion system includes the use of a waste heat boiler to recover waste heat that is produced as a result of the reaction of oxygen in the furnace gas duct. On the other hand, in the supressed combustion technique, the combustion gas is collected to be used as fuel through reducing air infiltration and inhibit combustion of the CO and by adding a skirt to the outlet converter mouth

The flue gas exit tempera ture from a boiler is usually maintained at a minimum of 200 o C, so that the sulphur oxides in the flue gas do not condense and cause corrosion in heat transfer surfaces. When a clean fuel such as natural gas, LPG or gas oil is used, the economy of heat recovery must be worked out, as the flue gas temperature may be well below 200 o C.
