Abstract

A process and devices with which the fused sulphur is removed from fossil fuels, preferably coke and petrocoke, ahead of the furnace or the like and is fused with an additive. In the combustion chamber, the additive with the fused sulphur is then sintered. The fuel is desulphurized at a temperature management controllable by an electronic process computer, at controllable residence times and pressure conditions in leading zones so that practically completely desulphurized fuel is burned in the combustion chamber. The sulphur components are removed with the additive via an ash removal plant. A combustion of the sulphur components of the fuel to SO.sub.2 within the combustion chamber does not occur.
