ABSTRACT:
The invention relates to a combustion process with cleansing of the waste gases by compressing, cooling and expanding said gases.
The invention provides a continuous process in which highly contaminated low-grade fuels having a high water content can be effectively burned and the waste gases efficiently cleansed, by subjecting the cooled waste gases, together with residual non-desired substances, to a rapid drop in pressure in one or more stages by means of an expansion means (5), whereat the input drive power of the compressor (3), required for compressing said gases, is so high that the temperature downstream of the expansion means (5) is sufficiently low for the condensation and precipitation of frozen contaminants in the waste gases, together with ice crystals.
The invention can be applied to all forms of combustion plants, primarily combined power and heating plants fired with fuel having a high sulphur and water content.
