METHOD OF CONTACT LIQUID HEATING Russian patent published in 2018 - IPC F24H1/00 

FIELD: power engineering.

SUBSTANCE: invention relates to the field of heat power engineering, namely to contact heating of the liquid with a gaseous medium. Method comprises contacting the heating gas and a layer of the heated liquid flowing down the inner surface of the flue. Heating gas is supplied to the flue from above, while the amount of heating gas is selected less, and heated liquid – more values that cause an increase in temperature internal surface of flue to the temperature of formation of scale on it.

EFFECT: invention allows increase the intensity of heating the liquid by expanding the temperature range of the heating gases, increasing the temperature head, increasing the speed of movement and turbulence of gases.
