REGASIFICATOR-GAS HEATER Russian patent published in 2019 - IPC F17C9/00 

FIELD: heating equipment.

SUBSTANCE: invention relates to heat engineering and can be used for regasification of liquefied natural gas (LNG) and liquefied petroleum gases (LPG), supplied from stationary storages (hubs) and mobile tanks in stationary and alternating gas consumption modes. Regasificator-gas heater comprises a burner device, a stack, a heat exchanger-heater consisting of two pipes – an external one with a blind end and an inner one with an open end facing the burner device, and forming an external and internal channels. Inner channel is interconnected with supply line of regasified liquid, and external channel is connected with outlet branch pipe. Heat exchanger-evaporator consists of two pipes – external with blind end and internal one with open end, and forming external and internal channels, wherein external channel of heat exchanger-evaporator is interconnected with gas outlet line, and heat exchanger-heater outlet branch pipe is communicated via throttling device with internal channel of heat exchanger-evaporator.

EFFECT: prevention of heat-transfer crisis and cavitation modes of liquid flow, as well as providing reliable and simple control of capacity and gas parameters in the main line.
