Abstract
The utility model discloses a water-coal-slurry device combustion device of a heating furnace and consists of a storage tank, a slurry feeding pump, a combustion pump, a pipeline, a compressor and a blower. The storage tank is connected with the pipeline, the slurry pump, the combustion pump and combustion device of the heating furnace. A mixing tank is arranged between the slurry feeding pump and the combustion pump, a filter is arranged between the combustion pump and the combustion device; the compressor and a blower are connected with the combustion device through a pipeline, a heat exchange device is arranged between the blower and the combustion device. The utility model has the advantages of simple structure, convenient to be used, low cost and can greatly reduce the production cost of the band steel.
Description
The utility model relates to a kind of burner, particularly a kind of rolling mill furnace coal-water fluid burner.
At present, the heating furnace major part of China steel rolling mill is a fuel with heavy oil, causes the production cost height of band steel, and the increase of the imbalance between supply and demand that produces along with heavy oil rise in price in recent years, and normally carrying out of steel production is with in influence.
The purpose of this utility model just is to overcome weak point of the prior art, provides a kind of simple in structure, easy for operation, with low cost, can reduce the heating furnace coal-water fluid burner of band steel production cost greatly.
The purpose of this utility model is to realize like this, it comprises: storage tank, slurry supply pump, combustion pump, compressor, air blast, storage tank links to each other with the burner of heating furnace by, pipeline, slurry supply pump, combustion pump, be provided with agitator tank between slurry supply pump and combustion pump, be provided with filter between combustion pump and burner, compressor, air blast link to each other with burner by pipeline, are provided with heat exchanger between air blast and the burner, burner is a single hole Y type internal-mixing nozzle, and axial impeller formula air register is equipped with in its inside.
The purpose of this utility model can realize that also burner is provided with water-coal-slurry, atomizing air, combustion air import by following technical measures, and axial impeller formula air register mixes inlet by pipeline with water-coal-slurry, atomizing air and communicates.
Compared to existing technology, the utlity model has simple in structurely, easy for operation, utilize cheap water-coal-slurry to be fuel, can reduce the advantages such as production cost of band steel greatly.
Accompanying drawing and drawing explanation
Fig. 1 is the utility model structural representation
Fig. 2 is the utility model burner structure schematic diagram
Below in conjunction with drawings and Examples in detail the utility model is described in detail, it comprises: storage tank 1, slurry supply pump 2, combustion pump 9, compressor 3, air blast 4, storage tank 1 passes through pipeline, slurry supply pump 2, combustion pump 9 links to each other with the burner 6 of heating furnace 7,9 of slurry supply pump 2 and combustion pumps are provided with agitator tank 10,6 of combustion pump 9 and burners are provided with filter 8, compressor 3, air blast 4 links to each other with burner 6 by pipeline, be provided with heat exchanger 5 between air blast 4 and the burner 6, burner 6 is a single hole Y type internal-mixing nozzle, axial impeller formula air register 14 is equipped with in its inside, burner 6 is provided with water-coal-slurry, atomizing air, combustion air import 13,12,11, axial impeller formula air register 14 is by pipeline and water-coal-slurry, atomizing air mixes inlet and communicates.Operation principle of the present utility model is, before water-coal-slurry is transported to storage tank 1 by automobile or train tanker vehicle, send into storage tank 1 by pump for mortar transmission, then by sending stock pump 2 that water-coal-slurry is sent into agitator tank 10, water-coal-slurry by agitator tank 10 stirrings, send into burner 6 by combustion pump 9 by filter 8, with the combustion air of sending into by air blast 4 through heat exchanger 5 preheatings, the atomizing air of compressor 3 compressions mixes the ejection burning at the single hole Y of burner 6 type internal-mixing nozzle, steel billet in the heating furnace 7 is heated, the axial location of blade that in use can be by adjusting vane type air register 14 is adjusted the length and the angle of flare of flame, to improve the programming rate of heating furnace, reduce the oxidization burning loss of steel billet, and the heat time heating time of shortening steel billet, improve production capacity, the atomizing wind pressure of being supplied with by compressor 3 is 0.25-0.35Mpa, and the combustion air that air blast 4 is supplied with is preheated to 30 ℃-40 ℃ through preheater 5, reach as high as 300-500 ℃, air quantity is 13000-15000M
3/ H guarantees that 7 times bringing-up section furnace temperature of heating furnace reach 1320 ℃.Simultaneously be provided with a plurality of doors of scratching in the ashes in heating furnace 7 bottoms, so that remove dust stratification, the utility model is simple in structure, easy for operation, utilizing cheap water-coal-slurry to be fuel, can reduce the production cost of band steel greatly, is the ideal device of band steel production with ribbing oil.
