STACK Russian patent published in 2013 - IPC F24B1/00 

FIELD: heating.

SUBSTANCE: stack for a stove, mainly for heating of steam bath premises, comprises a vertically aligned body, preferably made of a material on the basis of an iron alloy with carbon, the lower input part of which is connected with a source of hot gases, preferably, fuel combustion products in the stove, the upper output part - with environment. In the lower part of the stack body there is a shell with a bottom, forming preferably a circular reservoir for a steam-generating liquid, preferably, water, preferably, with aromatic additives, with the stack body, and a heat exchange material, preferably, stones. At the same time the upper output part of the specified reservoir is closed with a cover, preferably in the form of a truncated cone. Between the specified cover and the stack body there is a gap, preferably, circular one. Above the specified reservoir, in close proximity to it, coaxially with the stack body, there is a cylindrical jacket installed, preferably cylindrical one, made of at least two shells, inner and outer ones, installed coaxially with the circular radial gap relative to the stack body and to each other. Circular radial gaps between the stack body and the inner shell and between the inner and outer shells of the jacket are connected with the inner cavity of the circular reservoir for water via the specified circular gap between the cover and the body of the stack, at the same time the jacket at the ends is closed by profiled perforated bottoms.

EFFECT: increased heat emission of fuel combustion products, increased time of stove operation with invariable fuel consumption, possibility to produce heated steam with controlled temperature and moisture.
