The gas flow is ionized by its being caused to pass an emission electrode means (2) so that ions are formed and the polluant particles are given an electric charge. The particles are deposited by electrostatic attraction onto a combined collector electrode/heat exchanger surface (6), there also being generated a new aerosol by the gas flow being cooled as it passes said collector/heat exchanger surface, pollutants in the gas phase condensing onto the ions and electrically charged particles serving as condensation cores simultaneously as heat is recovered from the gas flow. The apparatus includes a heat exchanger (1) of the tube type, having a plurality of emission electrode means (2, 3, 4) inserted between groups of heat exchanger pipes. The collector electrode/heat exchanger surfaces on the pipes can be cleaned by a cleaning means (5) during operation of the apparatus, and in some applications the emission electrode means can also be automatically cleaned.
Method of simultaneously recovering heat and removing gaseous and sticky pollutants from a heated, polluted gas flow, said method being performed in a closed device, comprising the steps of
Apparatus for simultaneously recovering heat and removing gaseous and sticky pollutants from a heated, polluted gas flow, said apparatus including a heat exchanger (1) having a plurality of heat exchanger members (6) successively arranged in the gas flow direction, one surface of the members being swept over by the heated, polluted gas, the other surface thereof being swept over by a heat receiving medium, characterized by a plurality of emission electrode means (2-4) at mutual spacing in the gas flow direction between groups (1A, 1B, 1C) of heat exchanger members (6).
