The use of waste heat recovery to produce steam is integral to sulfuric acid plants.

Large quantities of heat are liberated both in the burning of sulfur and the conversion of SO2 to SO3.

A typical plant employs a firetube waste heat boiler at the outlet of the sulfur furnace, a steam superheater or second boiler between initial converter passes and, finally, economizers and low temperature superheaters to cool the gas prior to entering the absorbers.

More than twenty years of engineering and manufacturing the waste heat recovery equipment described above has earned Technotherm a global reputation for both dependability and economy.
