HEAT GENERATING METHOD FOR HEATING OF BUILDINGS AND CONSTRUCTIONS AND HEATING DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2011 - IPC F24J3/00 

FIELD: heating.

SUBSTANCE: heat generating method for heating of buildings and constructions involves pumping of heat carrier under pressure excluding cavitation in heat carrier flow, in heating device containing heat energy generator, as well as containing heat transfer system to consumer, which are connected to each other in closed circuit by means of supply and return pipelines, at least one circulation pump located in this circuit, and at least one recirculation pipeline installed with straight and return pipelines. At least one of the above recirculation pipelines includes at least one element containing confuser, diffuser and at least one annular groove made between diffuser and confuser. Annular groove is essentially triangular in cross section. The device for implementation of the above method is also proposed.

EFFECT: high economy of fuel or other heat-carrying agent in heat energy generator.
