Abstract

PROBLEM TO BE SOLVED: To carry out the recovery and re-utilization of waste heat by a method wherein waste heat from the flue of a boiler is transferred through sand and a heat pipe to effect heat exchange between outdoor air. SOLUTION: A heat recovery unit M, mounted in the flue A of a boiler, is constituted of a hot-air passage (a), a heating unit (b), a heat transfer unit (c) and a heat exchanging flow passage (d). Hot air from the flue A of the boiler for heating a vinyl house and the like flows the lower end of an outer case 1 into lateral direction after hitting a baffle plate and passes the hot-air passage (a) through a communicating hole 5 to heat a case, filled by sand 7, while the heated sand 7 heats a heat pipe 8 while developing far infrared ray effect and the internal space of an inner case 2 is heated by the heat pipe 8. In this case, a heat exchanging flow passage (d) is formed in the inner case 2 and, therefore, heat exchange of the heat from the heat pipe 8 is effected here and inflow air from an air inflow duct 9 is heated whereby hot air is taken out of a hot air outflow duct 10 and is utilized again to heat the vinyl house and the like.
