  • Thermal energy reusing system
    Patent number: 6530209
    Abstract: In a system for reusing a thermal energy of an air discharged from a heated air source to heat a combustion air to be supplied into a combustion device so that the combustion air is mixed with a fuel to be combusted in the combustion device, an air feeder sucks the combustion air and feeds the combustion air toward the combustion device, an inlet passage at an upstream side of the air feeder passes the combustion air toward the air feeder, and the inlet passage includes a first inlet port for taking the air from the heated air source through the first inlet port into the inlet passage to incorporate the air to the combustion air and a second inlet port for taking an atmospheric air through the second inlet port into the inlet passage to incorporate the atmospheric air to the combustion air.
