Combustion gas reversal valve 1a, air reversing valve 2a and the commutation of waste gas reversal valve 3a sequential, in the cycle 2, to combustion gas reversal valve 1a, combustion gas reversal valve 1a switches to the 12a position to fuel through gas flow control valve 4a, combustion gas arrives burner 12a, enter regenerative furnace 10a burning, air is infeeded by air blast 7a, through air flow rate adjustment valve 5a, again through air reversing valve 2a, this moment, air reversing valve 2a switched to the 12a position, and burner 12a is delivered in combustion gas, entered the burning of regenerative furnace and fuel mix.The flue gas that the regenerative furnace internal combustion forms arrives air reversing valve 2a through air pipe line again through burner 11a, arrives waste gas reversal valve 3a then, through exhaust gas flow control valve 6a, is extracted out by smoke extractor 8a, and 9a is discharged to atmosphere through chimney.Above cycle 1 and cycle 2 repeat.
Because smelting furnace etc. are in use many to be fuel with heavy oil, the ejection repeatedly of liquid fuel and cut-out will inevitably cause the fuel nozzle spout to stop up owing to coking, and the device among Fig. 1 also is not suitable for smelting furnace.
Summary of the invention

One heavy oil input channel, this heavy oil input channel communicates with the regenerative furnace furnace chamber, and its entry position that feeds the regenerative furnace furnace chamber is positioned at the centre of regenerative furnace furnace chamber, between first regenerator and second regenerator;
Wherein, between first regenerator and second regenerator, be connected with a pipeline, in the middle of pipeline, be provided with a reversal valve;
One side of described reversal valve links to each other with air-introduced machine, and opposite side links to each other with air blast;
Heavy oil enters in the regenerative furnace from the heavy oil input channel, combustion air is bloated by air blast, enter reversal valve by pipeline, enter second regenerator then, combustion air enters in the regenerative furnace after the second regenerator preheating, heavy oil and combustion air mixed combustion, and the flue gas that burning forms enters first regenerator, and enter reversal valve by logical flue gas, extract out by air-introduced machine;
Heavy oil enters in the regenerative furnace from the heavy oil input channel, combustion air is bloated by air blast, enter reversal valve by logical flue gas, after reversal valve switched, combustion air entered first regenerator, and combustion air enters in the regenerative furnace after the first regenerator preheating, heavy oil and combustion air mixed combustion, the flue gas that burning forms enters second regenerator, and enters reversal valve by logical flue gas, is extracted out by air-introduced machine.
Described first regenerator and second regenerator are arranged with the thermocouple that is used to add hot-air.
This device also comprises a flue control valve, and it is between air-introduced machine and reversal valve.
This device also comprises an air flow rate adjustment valve, and it is between reversal valve and air blast.
This device also comprises a pressure-regulating valve, and it is between reversal valve and air blast, by the air flow rate adjustment valve.
The utility model can be used for the smelting furnace of all size and pattern, owing to have only a fuel inlet oil-feed all the time, so the burner spout can coking.
