HEAT GENERATOR Russian patent published in 2008 - IPC F24H3/00 

FIELD: heating.

SUBSTANCE: invention refers to a heat engineering, particularly to heat generators designed for heating of gas, oil or other hydrocarbon substances through an intermediate heat carrier, and can be used in oil and gas industry. The heat generator contains a case, a reservoir of which is filled with an intermediate heat carrier, a burner with a combustion chamber, an exhaust pipe with a coupling flange, a fuel main, a heat exchanger, an additional heat exchanger; according to the invention a burner with the combustion chamber, the exhaust pipe with a coupling flange and the heat exchanger are arranged in the central portion of the case reservoir, at that the additional heat exchanger is designed as a set of spiral pipelines, enveloping the above said heat exchanger, inlets and outlets of which are united with toroid shaped collectors equipped with sleeves for input and output of a working medium.

EFFECT: increased efficiency of heat generator operation and reduced mass and dimension characteristics of the heat generator.
