AUTONOMOUS SYSTEM OF HEAT SUPPLY FOR OBJECTS AND SETTLEMENTS Russian patent published in 2022 - IPC F22B31/00 F24D10/00 

FIELD: energy.

SUBSTANCE: invention relates to the field of energy, in particular to autonomous heating systems for objects and settlements using natural gas. Initially, all consumers of thermal energy 4 were supplied with heat from a gas boiler 2. Natural gas is supplied to the boiler 2 from the main gas pipeline 13 through the supply gas pipeline 1. Hot water is supplied from boiler house 2 via heat network 3 to thermal energy consumers 4. To supply heat to new consumers of thermal energy 10, a pre-fabricated block-modular boiler plant 5 is installed, into which natural gas is supplied through gas line 6. From block-modular boiler plant 5 along heating network 9, hot water is supplied to consumers of thermal energy 10. In the event of an emergency, on the supply gas pipeline 1 or on the main gas pipeline 13, the shut-off and control valve 12 on the supply gas pipeline 1 is closed and the shut-off and control valve 11 opens on the supply line 8 of the vapor phase of liquefied hydrocarbon gas and the vapor phase of liquefied hydrocarbon gas (gaseous propane-butane) enters the gas boiler 2 and block-modular boiler plant 5 to generate hot water.

EFFECT: increase in the capacity of the autonomous heat supply system with an increase in the number of consumers of thermal energy and the provision of reserve fuel for the autonomous heat supply system when the supply of natural gas is interrupted.
