FIELD: energy.
SUBSTANCE: invention relates to the field of energy, in particular to autonomous heat supply systems for settlements using natural gas. Initially, all consumers of thermal energy 4 were supplied with heat from a gas boiler 2. To operate the boiler 2, natural gas is supplied from the main gas pipeline 13 through the supply gas pipeline 1. From the boiler house 2 through a closed heating network 3, the thermal energy of heated water is transferred to the thermal network 16 consumers of thermal energy 4 through the heat exchanger 14 in the heating point 15. To supply heat to new consumers of thermal energy 10, a prefabricated block-modular boiler plant 5 is installed, into which natural gas is supplied by gas line 6. From the block-modular boiler plant 5 through a closed heat network 9, the thermal energy of the heated water is transferred to the heat network 19 consumers of thermal energy 10 through the heat exchanger 17 in the heat point 18. In the event of an emergency, the supply gas pipeline 1 or the main gas pipeline 13 is closed shut-off and control valve 12 on the supply gas pipeline 1 and the shut-off and control valve 11 opens on the compressed natural gas supply line 8 and compressed natural gas enters the gas boiler 2 and the block-modular boiler plant 5 to produce hot water.
EFFECT: increasing the capacity of the heat supply system, as well as providing an autonomous heat supply system with reserve fuel and increasing the reliability of its operation.
