HEAT SUPPLY METHOD Russian patent published in 2012 - IPC F24D3/08 

FIELD: power industry.

SUBSTANCE: heat supply method as per which the main heat load of centralised heat supply system is covered with base heat source is described; system water heaters of extraction turbines of CHPP are used as the above base heat source; peak heat load is covered with independent heat source connected to supply and return pipelines of local consumer heat supply system connected via supply and return pipelines to supply and return main lines of centralised heat supply system. The peculiar feature of the proposed heat supply method is that independent heat source is used as basic heat source at reduction of flow rate of delivery water in main supply line of centralised heat supply system, which is controlled with flow sensor, below specified values; for that purpose, local consumer heat supply system is disconnected from supply and return main supply lines of centralised heat supply system with shutoff elements, and circulation of delivery water is performed through independent heat source and local heat supply system by means of circulating pump.

EFFECT: higher reliability.
