HEATING SYSTEM, FOR EXAMPLE, OF NATURAL GAS Russian patent published in 2017 - IPC F24H4/06 

FIELD: heating.

SUBSTANCE: invention relates to heating, in particular to heating of fluid medium using injection pumps or compressors. Heating system for example of natural gas comprises source of heating medium and plate-type or tubular heat exchanger, latter is integrated in main gas line at inlet of gas into gas-distributing station. Parallel to heat exchanger in main gas line bypass is built, equipped with adjusting shutter. Source of heating medium is boiler plant or heat supply network. Boiler plant is located on explosion-proof distance from main gas pipeline and connects with heat exchanger via heat-insulated pipelines with coolant recirculation by means of compressor or pump. Gas supply pipeline to furnace of boiler plant is connected to main gas pipeline, provided with adjusting valve. Gas heating system is equipped with gas heating temperature control unit within specified limits, which includes temperature sensor integrated into main gas line before inlet of gas into gas-distributing station, signal from which is fitted to gas temperature control unit, control adjustment valve of gas supply to furnace of boiler plant and bypass adjusting shutter.

EFFECT: such system is explosion-proof, easy in repair and servicing, as well as prevents formation of hydrate in pipes of heat exchanger.
