TL;DR: In this paper, 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, the thermal behavior of a multipass process gas heater has been investigated using the zone method of analysis, with the aim of estimating the accuracy of previous predictions based on an extended two-flux model of the radiation field.

TL;DR: Combined heating and emergency current appts for buildings comprises a gas heater, gas engine, generator, gas compressor, and heating bodies (convectors, heat exchangers) such that a closed gas (air) circuit is formed between the heaters, motor, cooler and compressor.
Abstract: Combined heating and emergency current appts. for buildings comprises a gas heater, gas engine, generator, gas compressor, and heating bodies (convectors, heat exchangers) such that a closed gas (air) circuit is formed between the heaters, motor, cooler and compressor. The motor drives the emergency current generator and compressor. The cooler acts directly as a space heater and/or water heater for a hot water supply. The motor and compressor have high-r.p.m. rotors on the volumetric displacement principle, and are rigidly intercoupled together. The appts. does not pollute the atmos. and can be driven with given energy sources.
