TL;DR: In this article, a diver's gas heater is used to heat the breathing gas for added comfort in cold water, and a portion of the hot water is tapped off to maintain heating around the short length of breathing gas hose between the heat exchanger and the diver's helmet.
Abstract: A diver's gas heater, for use with a hot water heated suit, to heat the diver's breathing gas for added comfort in cold water. Hot water from a surface installed source is pumped through a hose to the diver's suit and the heater is installed directly in the hot water supply hose. The hot water passes through a tubular heat exchanger and the breathing gas flows through an annulus around the water conducting tube. A portion of the hot water is tapped off to maintain heating around the short length of breathing gas hose between the heat exchanger and the diver's helmet.

TL;DR: In this article, a gas burner heating through a heat exchanger and a regenerator heated by the burner can be switched off without any loss, without the need of a switchboard.
Abstract: PURPOSE:To provide a heater characterized in that a gas burner heating through a heat exchanger and, during this heating, a heating with a regenerator heated by the burner can be switched without any loss.

TL;DR: In this paper, a process for regenerating SO2-laden active carbon or coke is described, where part of the stream of desorbed gas is introduced into the regenerator below the hot active carbon/coke zone and removed at a higher level in a preheated condition.
Abstract: In a process for regenerating SO2-laden active carbon or coke, part of the stream of desorbed gas is introduced into the regenerator below the hot active carbon/coke zone and removed at a higher level in a preheated condition. The gas is then further heated in an external gas heater and returned to the regenerator. The active carbon/coke migrates downwards through the regenerator. The process removes all of the heat from the outflowing materials except the heat remaining in the desorbed gas passing to a further process (e.g. sulphur recovery and that in the active carbon) coke, which can be recovered using cooling water. Used in desulphurisation of process gases, esp. flue gases from power stations.

TL;DR: In this article, the authors propose to close a valve for controlling the passage of gas by detecting those boiled over while a gas heater is being used for cooking material, and then close the valve manually.

TL;DR: A gas heater for an incinerator comprises a cylindrical sleeve (13) with a shell (12) to form inner and outer flow spaces and a bellows (26) located axially beyond the sleeve and connecting it expandably to the shell at one end as discussed by the authors.
Abstract: A gas heater (11) for an incinerator comprises a cylindrical sleeve (13) with a shell (12) to form inner and outer flow spaces (14,15) and a bellows (26) located axially beyond the sleeve and connecting it expandably to the shell at one end. Gas to be heated flows through the outer space and a burner (36) generates hot gas in the inner space. An extended heat exchange surface (41) projects outwardly from the sleeve into the outer space and a baffle (37) is mounted within the sleeve to channel the hot gas into a convection passage. The baffle is cylindrical with a closed end to provide a convection passage at the exit end of the sleeve.

TL;DR: The pref. alumina grains impregnated with 1-2 wt.% Pt. were treated for more than 0.4 seconds at 50 degrees C as mentioned in this paper, where the Pt catalyst layer was pref.
Abstract: The gas mixt. is continuously circulated through a Pt catalyst layer for oxidation of the CO produced during welding to CO2, and the gas then flows through a CO2 absorber. The catalyst layer is pref. alumina grains impregnated with 1-2 wt.% Pt. The gas mixt. is pref. treated for more than 0.4 seconds at 50 degrees C. The pref. plant includes a dust extractor, fan, gas heater, catalyst chambers, CO2 absorbers and a cooler.
