METHOD AND DEVICE FOR GENERATING EXCESS PRESSURE OF GAS IN VERTICAL PASSAGE Russian patent published in 2007 - IPC F23L17/00 

FIELD: heat power engineering.

SUBSTANCE: method comprises supplying the gas to the gas-discharging passage, humidifying and heating the gas in the base of the gas-discharging passage, and subsequent heating the gas by means of reflected heat flux throughout the height of the passage. The device comprises load-bearing housing with gas-discharging passage, source of heat radiation, and humidifier. The bottom section of the gas-discharging passage is provided with a gas duct made for permitting control of the gas supply. The inner side of the gas-discharging passage is corrugated or shaped into wave-like surface, which is made of a heat-reflecting material. The reflector is mounted above the mouth of the load-bearing housing.

EFFECT: enhanced excess pressure and draft.
