METHOD AND DEVICE FOR REDUCING THE POLLUTANT EMISSION OF SMALL HEATING SYSTEMS

摘要

The invention relates to a method for reducing pollutant emissions of exhaust gases from small heating installations, taking the use of calorific value into account, and to a suitable device therefor. The exhaust gas flows out of the heating boiler into a chamber (1) and is conducted, by means of guide mechanism (4a,4b), via at least one heat exchanger (5)) in order to dissipate part of its thermal energy. Another guide mechanism (4c) is subsequently used to conduct the exhaust gas to an area of finely distributed drops of water (7) that are formed by a spray system (8) and that have a lower temperature than the exhaust gas. The pollutants contained in the exhaust gas are at least partially dissolved in the drops of water (5) and removed therewith in the form of a consdensate, whereby they are carried away, without entering into contact with the heat exchanger (5) of the chamber (1), into a water bath (13) where they are conducted via at least one other heat exchanger (15). The water from the water bath (13) is subsequently re-utilized to form water drops (7) in the chamber (1).
