Abstract
The invention relates to a method for reducing a chimney draught in an upstream connected exhaust gas cleaning system consisting in immersing a chimney tube (') provided with the open top part thereof in a bath in such a way that a liquid (condensate) collected therein forms a liquid barrier closing the exhaust gas input end of the chimney tube with respect to environment. In order to remove the exhaust gases from the upstream connected exhaust gas cleaning system, at least one part of the chimney tube cross section is exposed by lowering the liquid level under the edge thereof. Said lowering of the liquid level can be carried out by lowering the bath.
