Mechanism is mainly made of thermal conductive shell, radiant tube, igniter, heat exchanger and connecting tube, and the spoke of W shapes is provided with thermal conductive shell
Pipe is penetrated, which is made of ignition part, main combustion portion and exhaust portion, and the point for being exposed independent from thermal conductive shell is set at the both ends in main combustion portion
Fiery portion and exhaust portion, are separately installed with igniter and heat exchanger, between igniter and heat exchanger in ignition part and exhaust portion
It is connected with connecting tube.
Moreover, the furnace body is made of furnace body inner core, insulating layer and furnace body shell, furnace body inner core is piled up by insulating brick,
The outside of furnace body inner core is provided with insulating layer, the outside of insulating layer is provided with furnace body shell.
The advantages of the utility model and have the beneficial effect that：
1. the high annealing furnace of a thermal efficiency, by being designed as adding by traditional heating arrangements set on inboard wall of burner hearth
Heat engine structure is staggered the structure of setting up and down, ensure that the heating requirements to strip top and bottom；And by the way that traditional structure is single
Radiant tube be designed as W-shaped radiant tube, substantially increase heat dissipation area, improve the thermal efficiency；By igniter on radiant tube and
The setting of heat exchanger, during work, air is preheated enter igniter, with combustion gas mixing after, raise fuel gas temperature, greatly improve
Firing temperature and ignition part temperature.
2. the high annealing furnace of a thermal efficiency, passes through the double-layer heat insulation shape for being combined Proper Design for insulating brick and insulating layer
Formula, reduces scattering and disappearing for heat, reduces thermal losses, save the energy.
3. design is scientific and reasonable for the high annealing furnace structure of the utility model thermal efficiency, there is the high thermal efficiency, the saving energy, subtract
The advantages of lacking thermal loss, being easily achieved, is a kind of annealing furnace with higher innovation.
