BOILER-HOUSE OF MILITARY FACILITY OPERATING ON LIQUEFIED NATURAL GAS Russian patent published in 2020 - IPC F22B31/08 F22B33/18 

FIELD: heat power engineering.

SUBSTANCE: invention relates to heat engineering and is intended for generation of heat energy in boiler houses using liquefied natural gas (LNG). Boiler house of military facility includes boiler plant and LNG cryostat, connected with LNG evaporation system and gas heating before its supply to furnace of boiler plant. Boiler house is equipped with buried reinforced concrete structure divided into two sections by heat-insulated wall. In the first section there is LNG cryostat with liquefied natural gas refueling line, and in the second section there is LNG heat exchanger and heat exchanger-heater of atmospheric air supply line to boiler plant. Line of atmospheric air supply to the boiler plant before the entrance into the buried structure passes through the heat exchanger with the electric heater and is equipped with a compressor and a heat exchanger-air heater before its supply into the furnace. Heat exchanger-heater of evaporated LNG and heat exchanger-air heater are located in heat exchanger, through which flue gas removal line of boiler plant passes.

EFFECT: possibility of accurate control of heat energy flow from a heat source for evaporation of the required amount of LNG, higher safety and reliability of operation of storage facilities with cryogenic fuel.
