Process and device for combined heat exchanging and gas cleaning, especially by heating of fossil fuel in order to achieve high efficiency in heating plants or similar air technical plants. The invention is characterized in that cleaning of the gases are accomplished by the following: - by injecting basic substances and/or recirculating water into the gas reactors of the gas cleaner and the heat exchanger, (a1 or b1), in one of the two equal units (a and b). - by dust separation on the filter cassette of the same unit (a2 or b2). - by a chemical reaction in the mass in the primary heat exchanger of the same unit (a3 or b3). - the gases are led through the mass in the secondary heat exchanger of the same unit (a4 or b4), where water is separated by condensation, at which the separated water is led back to the gas reactors (a1 or b1) of the unit (a or b). - gas exchanging is accomplished by a simultaneous changing of position of gas exchangers (12 and 13) and by making the heated gas, which has been heated by a regenerative mass in the heat exchangers (a4 or b4 and/or a3 or b3), work partly as cleaning air for the filter cassette (a2 or b2), partly as heated process air or ventilating air. |
