FIELD: power engineering.SUBSTANCE: heating device comprises the first channel, where a non-ignited gas is burnt, containing fuel, injected with speed of a flow from a nozzle hole, having a smaller size compared to the distance of flame extinguishing, so that in this manner flame is maintained, at the same time providing for a flow of a combustion gas generated as a result of ignition process, the second channel arranged around the first channel and providing for a flow of a non-ignited gas, supplied through the specified nozzle hole, and the third channel, surrounded with the first channel and providing for supply of a liquid to be heated.EFFECT: stabilisation of flame in a combustion chamber and increased energy recovery of a heating device.8 cl, 13 dwg |
