Heating chamber, and separated between the gas combustion chamber and workpiece heat room by carborundum Muffle plate；In the body of heater
Side is provided with the first fuel burner nozzle, is provided with the second fuel burner nozzle in the opposite side of the body of heater, and first combustion gas is burnt
Mouth and the second fuel burner nozzle communicate with the inside of burner hearth, and workpiece is transported to the workpiece heat room of burner hearth by loading and unloading operating desk
In heated, and the discharge end slideway being connected with its internal transport channel is provided with the side of the body of heater.
Further, first fuel burner nozzle and the second fuel burner nozzle are heat-accumulating burner, and first combustion gas
Burner and the second fuel burner nozzle connect with gas pipeline or fuel cartridge body phase.
Further, the non-oxidation combustion type forge furnace also includes storage bin, feeding distribution mechanism and timesharing feeding machine
Structure.
Compared with prior art, the beneficial effects of the utility model are：The utility model when in use, by by burner hearth
Two parts are designed as, top is divided into gas combustion chamber, can ensure stability during burning, and bottom is divided into workpiece heat room,
It can realize and workpiece is heated, and carry out nitrogen protection to prevent oxidation.First fuel burner nozzle and the second fuel burner nozzle exist
Heat-accumulating burner is used from upper, the first fuel burner nozzle is arranged in one end of body of heater, and the second fuel burner nozzle is arranged in body of heater
The other end, when one of burner works, another burner, which does not work, to be served only for discharging fume, and the flue gas of smoke evacuation passes through heat storage,
And heat heat storage, the flue gas finally discharged can be responsible for smoke evacuation below 300 DEG C, after heat storage reaches certain temperature
Burner start working, another burner be stopped and start smoke evacuation and accumulation of heat.Combustion can be made by this regenerative combustion technology
The thermal efficiency of burning reaches 75%.The effective heat energy for utilizing natural gas, so as to reduce overall production cost.
