Operating gas heater for thermal power plants
TLDR
In this article, the authors describe a gas heater intended for use in a thermal power plant in which at least the greater part of a gaseous working medium, preferably air, describes a closed circuit, being raised to a higher pressure in at least one compressor, then brought to a high temperature.Abstract:
This invention relates to a gas heater primarily intended for use in a thermal power plant in which at least the greater part of a gaseous working medium, preferably air, describes a closed circuit, being raised to a higher pressure in at least one compressor, then brought to a higher temperature...read more

Hot air generator with variable length conduit
TL;DR: In this paper, the authors describe a hot air heating system with a plurality of interconnected units each including an inner and outer sleeve spaced to define an annular chamber there between with a heat generating means associated with the first of said units and having an associated blower or suction fan to draw ambient air into the system and force such air through the passageway defined by the interconnected inner sleeves which form a combustion chamber and through the annular passageways defined by interconnected annular chambers which formed a heat exchanger chamber, the end of the system being closed and having a discharge
