FIELD: construction.
SUBSTANCE: invention related to the field of caps for flues. A cap for a flue comprises: a body made as capable of covering at least the upper part of the flue and comprising an expansion chamber, where emissions arrive from the upper part of the flue, a diffuser for scattering of emissions from the upper part of the flue into the expansion chamber, at least one air inlet hole made as capable of air sending through it into the expansion chamber, at least one outlet hole made as capable of air discharge from it or emissions discharge from the expansion chamber. The body is arranged so that emissions released from the upper part of the flue are diffused and expanded, arriving to the expansion chamber, and inside the body there is lower pressure pulled for draught of emissions from the upper part of the flue into the expansion chamber.
EFFECT: development of lower pressure in a flue channel, reduced quantity of emissions.
