HOT BLAST GAS HEATER Russian patent published in 2005 - IPC

FIELD: heat engineering, namely accumulator type gas heaters, possibly used at developing hot blast gas heaters for aerodynamic tubes.

SUBSTANCE: gas heater includes cylindrical heat accumulating adapter sealed in housing near end of gas outlet. Novelty is that heater includes rod arranged along axis of heat accumulating adapter, supporting grid and cylindrical gas-tight casing. Heat accumulating member of adapter is made of thin corrugated strip whose one end is secured to rod. Corrugated strip is twisted around rod in the form of compact coil arranged together with supporting grid in casing. Height of strip corrugation is equal to thickness of strip.

EFFECT: improved design of heater due to its lowered hydraulic resistance.
