GAS COIL UNIT Russian patent published in 2016 - IPC F24H3/00 

FIELD: heating.

SUBSTANCE: invention relates to heat supply systems of various facilities for both land and underground purposes, and is intended for producing heat energy (hot air) and its supply to facility. Gas coil unit for indirect heating of plenum air includes container type lodgement, in which there is an air heating module and a system for automated control and monitoring of process equipment, air intake and plug for discharge of combustion products. Fan burner performs heating of heat-resistant combustion chamber walls. Fuel combustion products, due to pressure created by fan burner, pass through a heat exchanger, heated and released through plug. Atmospheric air is supplied to annular space of heat exchanger, is heated and fed into combustion chamber jacket convective is heated to preset temperature, then fed into additive to plenum ventilation of rooms or to a ventilation air mine.

EFFECT: improved efficiency and safety of gas air heating plant due to new atmospheric air supply circuit for heating and application of automatic control and monitoring.
