ABSTRACT:
The invention relates to gas-, or oil-burning warm water, hot water or steam boilers, mainly for the supply of households, communal institutions, and industrial plants, the surfaces of which surrounding the furnace are formed as membrane walls having annular passageways connected by thin plates, the passageways receiving the heat carrying agent.
The essence of the invention is that the flue-tube of the boiler is formed as a body of rotation with varying cross section conforming to the extent of heat radiation, and the flue-tube is surrounded by another convective heat exchanging flue-tube formed as a membrane wall conforming to the shape of the inner flue-tube, the convective heat exchanging flue-tube defining a flue passage with the inner flue-tube, the linings of the membrane wall of the annular passageways of the outer flue-tube being offset in relation to the passageways of the membrane wall of the inner flue-tube.
