Get A QuoteIf additional steam is required, the exhaust gas can be used as preheated combustion air for firing additional fuel in the waste-heat boiler; thus an additional 13 000 kg/h steam at 1.75 MPa could comfortably be raised, increasing the overall thermal efficiency to more than 70% – and the supplementary fuel could be heavy oil.
