METHOD OF LIQUID HEATING IN THE VERTICAL STATIC TANK WITH FLAT BOTTOM THE HIGHT OF WHICH IS OVER THE BOTTOM SIZE Russian patent published in 2012 - IPC F24H1/18 

FIELD: heat engineering.

SUBSTANCE: invention can be used to heat technological liquids in static tanks. The method has it that the liquid is divided into two parts. One of the parts is located in the tank the bottom of which is heated from the outside with directed infrared light, the sources of which are located steadily under the bottom so that their radiation is perpendicular to the bottom surface. The second part of the liquid is located in the steady pipe parallel to the tank outside which is hydraulically connected to the tank with ends in the upper and lower parts of the tank. This part of liquid is heated inside the pipe by electrode boiler. At this initially the liquid shall be upper than upper connection of the pipe and tank. Moreover, infrared radiators and electrode boiler are connected parallel to power output of automatic "voltage-temperature" regulator. Its power input is connected electrically to industrial network and the control input of the regulator is connected electrically to temperature sensor which is fixed on the outside wall of the tank between the tank liquid stall.

EFFECT: method allows ensuring heating of liquid up to set temperature and maintain this temperature in automatic mode.
