Solid fuels are gasified to a fuel gas for subsequent efficient combustion causing no harm to the environment by supply of a reaction gas-like oxygen or preheated air, eventually with an addition of recirculated fuel gas and/or water vapor. The fuel is thereby disposed in a uniform way in a limited zone of gasification (8). Gasification is carried out in a pulsed manner by pulsations in the supply of reaction gas at a comparatively high frequency, said pulsation being produced by means of pulsing means (13) or by cyclic variations in the composition of the reaction gas. |
