CONDENSATION HOT-WATER BOILER FOR EXTERNAL ACCOMODATION Russian patent published in 2008 - IPC F24H1/00 

FIELD: heating.

SUBSTANCE: invention is intended for heating water and can be used for heating. The condensation hot-water boiler for external accommodation contains a heat-insulated case with a heat-insulated vertical gas-tube boiler with a gas burner is placed inside, with a direct branch pipe of the boiler, connected by the automatic thermostatic crane with a direct line heating system of the building, gas pipes with turbulators placed in them, a chimney. In the smoke collector of the boiler is established an additional heat exchanger in the form of a corrugated non-corrosive pipe, connected by one branch pipe with a return line of the heating system of the building, and the second branch pipe - with a return pipe of the gas-tube boiler. Gas pipes contain turbulators with protective washers from condensate drops which are removed from edges of gas pipes by brackets of the turbulators, whose diameter is equal clearance between the protective washer and the edge of the gas pipe, and the base of the smoke collector contains a condensate outlet tube. The invention ensures cost reduction of the installation, increase in efficiency.

EFFECT: cost reduction of the water-heating installation, increase in efficiency.
