Abstract
Wet waste (1) is dried in a drier (3) by a blowing through of the flue gas (7) from the combustion of already dried waste and an appropriately amount of auxiliary air, and the heat from the combustion is generated by means of a scrubber (10) also cleaning the air for fume and dust particles, as well as certain nitrogen and sulphur and unpleasantly smelling compounds. Subsequently, the wash water releases the heat to a heat consumer through a heat exchanger (12), and impurities are precipitated in the clearing tank (15), while condensed water from the waste is carried away through a vent pipe (14).
Claims8
A method of extracting heat from manure, sewage mud, and other wet waste by combustion, said method comprising a combined drying-, combustion-, and steam-condensing-process, characterised in that up to the entire amount (7) of flue gas from the combustion of already dried waste is mixed with cold auxiliary air (8) to an appropriately low temperature and pressed through the wet waste in the drier (3) and on to a scrubber (10), wherein the wash water absorbs the heat and transfers it to the site of use, through a heat exchanger (12).
