A heat recovery device (1), particularly for reducing energy consumption in heating sanitary water for residential use or for industrial use by reducing the temperature of the combustion gases and of the particles dispersed by stacks of heating boilers. The device consists of a tubular element (2), which has an inlet (5) for the water drawn from the aqueduct, which flows along a coil of tubes (4) up to the exit (11) toward the heating boiler. The tubular element (2) also has an opening (15) for the inflow of the combustion gases that arrive from the heating boiler and exit through a second opening (24) after flowing around the coil that contains the water drawn from the aqueduct. The device thus allows savings in heating water for domestic and industrial uses and also allows a reduction in the emission of fine particles. |
