ABSTRACT:
A method of heating gases for combustion, operating turbines, and heating of a material and the like comprises the steps of providing a melt deposited in a vessel including two vessel elements and selected from the group consisting of a metal, a slag which is a mixture of metal oxides and nonmetal oxides, and a metal and a slag, supplying coal, air, fluxes and hot flue gases into the melt, passing the flue gases leaving the melt through a gas heater, passing a gas to be heated through one of the vessel elements, circulating the melt between the vessel elements, and supplying the gas which has been heated during passing through the one vessel element, to a gas consumer.
