Abstract

The process for the combustion of wood chips or the like, generating fumes low in noxious substances under continuously controllable furnace output, comprises first degassing the wood material in a pyrolysis chamber by external heating and with greatly substoichiometric primary air admixture, then introducing the resulting carbonisation gases into a separate reduction chamber and heating them therein to a temperature at which a reduction of the nitrogen oxides present in the carbonisation gases by the high carbon monoxide content of the carbonisation gases takes place, then passing the carbonisation gases downstream of the reduction chamber into a separate combustion chamber, at whose inlet the full combustion of the carbonisation gases is initiated by feeding combustion air and in which a spinning flow is forced by means of baffle devices in the combustion chamber onto the resulting flame, and contacting the fumes leaving the combustion chamber with the outside of the combustion chamber and with the outside of the pyrolysis chamber for heat release to the chambers and then passing them through water-cooled heating surfaces to generate useful heat. <IMAGE>
