COMBINED HEAT SUPPLY SYSTEM Russian patent published in 2009 - IPC F01K17/02 

FIELD: heating.

SUBSTANCE: present invention pertains to heat-and-power engineering and can be used in combined heat supply systems. The combined heat supply system has a thermal gas-turbine, gas-piston or steam electricity generating unit with heat exchangers - heat utilisers, cooling water and exhaust gases, which are included in the heat supply circuit of the heat consumer with heating systems and hot water supply. After the heat exchanger, the exhaust gases heat utilisers along the channel of exhaust gases, there is series-connection of a gas furnace and process load of hot gas - driers, burning and/or thermal installations. In the circuit of the heat supplier, there is an air heat exchanger for heating air coming into the gas furnace. The heat exchanger - exhaust gases heat utiliser along the channel of exhaust gases has a bypass-channel.

EFFECT: increased utilisation of waste heat and efficiency of thermal process, using hot gases.
