Method for heating liquid heat carrier and a device for carrying out said method

Abstract

The proposed heating method includes supplying a liquid heat carrier to a heating area by means of turning it about the cylindrical surface of a heater in such a way as to form an axially symmetric swirl flow, the trajectory of each heat carrier particle being tangent to the surface of the heater the temperature of which is higher than the critical thermal point of the heat carrier. The heating device contains a heat exchanger having a cylindrical body, tangentially positioned pipes for supplying the cold heat carrier and pipes for discharging the hot heat carrier. The heater having a cylindrical surface is coaxially arranged in the cylindrical body. The heating device contains an expansion tank, binding pipes and heat exchangers. The temperature of the heater is controlled by means of thermocouples. An electric heat source (a resistance helix) is located in the heater. The heating device has a high efficiency of heat transfer from the heater to the heat carrier due to the double phase transition: water-steam-water.
