FIELD: heat power engineering.
SUBSTANCE: heat generator comprises furnace with burner, heat exchanger, and gas duct. The burner is shaped into a cap diverging upward and is provided with slot grooves on its side for supplying air for burning and opening in its bottom section for supplying fuel. The heat exchanger is provided with three axially aligned cylinders that define inner and outer tanks that are interconnected and filled with heat agent and intermediate space interposed between the tanks. The gas duct has rectilinear section and spiral section formed in the intermediate space.
EFFECT: enhanced efficiency.
