Fremgangsmåte for å utnytte varmen i rökgasser som inneholder kondenserbare komponenter og apparatur for utförelse av denne

摘要

The invention relates to a method and a device for utilizing the heat of flue gases from combustion apparatus while simultaneously removing condensable elements from the flue gases and reducing the corrosivity of the flue gases. The method is applicable to all types of combustion apparatus where a combustion zone generates hot flue gases that are cooled in one or more heat exchangers that transfer the utilizable heat to a liquid or a gas. The method is also suitable for apparatus with considerable load fluctuations, where the fuel supply must be adjusted to the heat load. This is achieved by separating the flue gases from the heat exchangers by cooling the flue gases by means of a particulate material (2, 13) which absorbs the condensable substances, and by circulating the particulate material between the flue gases and heat exchangers (10) that transfer heat to the hot liquid or gas.
