SYSTEM FOR HEATING OIL AS HEAT CARRIER USING BOILER FLUE GAS WASTE HEAT Russian patent published in 2016 - IPC F24H7/00 

FIELD: energy.

SUBSTANCE: invention can be used to recycle waste heat boiler flue gases by means of heat transfer with oil. System for heating oil heat carrier using waste heat of boiler flue gases includes an economiser and air heater located in flue. System additionally includes an oil heater of heat transfer, which is located inside chimney before economiser and is connected to a device of heat consumption through first circulating pipe and circulation pump located on first circulation pipe and oil separator gas connected to expansion slot, connected with oil tank and oil pump, system is equipped with device for recycling and return exhaust gas heat for air heater containing heat absorbing and heat release interconnected with each other second circulation pipe, heat absorption element is located inside flue pipe for air heater.

EFFECT: system for heating oil as a heat carrier, using boiler flue gas lowers temperature of exhaust gas boiler, uses recycled heat for heating heat carrier.
