HEATER FOR TRACK HEATER Russian patent published in 2019 - IPC F23C3/00 F22B7/00 

FIELD: heating.

SUBSTANCE: invention relates to liquid medium heaters, in particular, to furnaces for track heaters with liquid heat carrier. Heater for track heater is U-shaped tube and is equipped with through overflow tubes arranged in the furnace convection zone at an angle to the horizontal. Through overflow tubes are arranged in staggered order at an angle to horizontal 25–90°, and through diameters outer diameter overflow tubes is 36–70 mm.

EFFECT: invention allows reducing temperature of flue gases, increasing surface of heat exchange of convective zone by more than two times, increasing efficiency factor, increasing heat output of track heater.
