HEATING DEVICE Russian patent published in 2018 - IPC F24V99/00 

FIELD: heating.

SUBSTANCE: invention relates to heating devices and can be used in various industries, where liquid heating is required. Heating device comprises the heat energy generator, the heat transfer system to the consumer, which are connected to each other in a closed circuit by means of the supply and return piping. In this circuit the network pump is located and at least one recirculation line with the straight and return pipelines is installed, in which at least one element is installed, which contains the confuser, the diffuser and at least one annular groove that is made between the diffuser and the confuser. Operating method of the heating device includes transferring the heat transfer medium in the circuit, which includes at least one element that contains the confuser and diffuser, this element is located in the recirculation line. In this case, the transfer of the coolant is carried out under pressure, which excludes the appearance of cavitation in the flow of the coolant.

EFFECT: such an execution of the heating device and its operating method allow to optimally consume energy for obtaining heat, to regulate the heat transfer to the consumer.
