FIELD: heating. ^ SUBSTANCE: invention relates to heating engineering, in particular to devices for heating liquids, and can be used in the heating system, for industrial and domestic needs, for heating directly in the line of viscous liquids. The problem is solved in the device for heating liquids containing a heat generator with an output pipe, a working network pump with electrodrive connected to the heat generator, the supply and return lines with shut-off valves ensuring relationship of a heat generator with heat exchangers, insulated and hermetically sealed heat exchanger equipped with a turbine and mechanically linked to electric motor and located between the outlet pipe and the supply line, while the outlet pipe of the heat generator is designed as a narrowing nozzle on which inner surface curved grooves are made lengthwise located from the inlet to the outlet and made with a profile as a swallowtail, and a circular groove is made near the input hole of narrowing nozzle, which is associated with curved grooves and connected to the device of removal dirt, curved grooves. ^ EFFECT: increased reliability during prolonged operation of the device due to removing intense destruction of the turbine blades during mechanical effects of particulate matter. ^ 2 dwg |
