Title:
HEAT TREATING APPARATUS
Document Type and Number:
Japanese Patent JPH11142062
Kind Code:
A
Abstract:
To efficiently thermally recover from a combustion exhaust gas.
A heat exchanger 10 is arranged at an upper surface side of a furnace body 1 substantially in contact with the body 1. A combustion exhaust gas is guided to the exchanger 10 via a combustion exhaust gas passage (flue) 5 arranged to penetrate a ceiling 1d of the body 1, and the gas is heat exchanged with a combustion air for burning a fuel gas. Thus, a heat radiation at a route is prevented to efficiently thermally recover it.
