Abstract:
PROBLEM TO BE SOLVED: To attain a uniform temperature distribution in a furnace main body without reducing thermal efficiency.SOLUTION: A heating furnace of this invention comprises an object space 212a in which an item to be burnt is arranged; a furnace main body 212 enclosing the object space; a tight-closing type gas heater including a combustion chamber where fuel gas is ignited, a feeding part where fuel gas flowed from a flowing hole toward the combustion chamber, a feeding-out part where the exhaust gas generated by combustion is guided, a partition plate parting the feeding part and the feeding-out part to pre-heat the fuel gas by heat of the exhaust gas, a radiation surface heated by the exhaust gas flowing at the feeding-out part to transfer radiation heat to an object to be burnt, exhaust hole for discharging exhaust gas out of the main body and arranged in the furnace main body; an exhaust heat transfer part [a heat insulation pipe 222a]. The exhaust heat transfer part is formed between the tight-closed type gas heater and the burnt object arranged in the object space and arranged at any location except the radiation spaces 212b for transferring radiation heat to the burnt object.SELECTED DRAWING: Figure 8
