Abstract
Heat is supplied to chemical reactions, especially reactions involving the cracking of hydrocarbons for producing gas, by the combustion of fuels with heated combustion air followed by a heat exchange extraction of sensible heat from the flue gases produced by the combustion for heating air for the combustion. The hot reaction product is at least partly air cooled and the resulting heated cooling air is passed at least partly through the air preheater before the air is used as heated combustion air.
