Technical field
This utility model relates to Industrial Stoves heating burner, especially a kind of scalable pure oxygen combustor.
Background technology
On Industrial Stoves, the overwhelming majority will use the industry kilns such as pure oxygen burning heating technique, such as glass, iron and steel, nonferrous metallurgy, pottery at present.In combustion heating technique, the equipment of most critical is burner, it is all the thermic load amount by kiln and the technological requirement specification and the quantity that determine burner when being commonly designed, but the product of burner supplier is not can to mate completely with off-gauge kiln, or the specification of product is few, so the type selecting that will there is burner is difficult, very difficult many-side meets the requirement of production technology.Such as: although the ability of burner enough meets the requirement of kiln temperature, but difficulty meets the requirement that in kiln process system, temperature stabilization controls.Or in the case of meeting temperature stabilization control, the position that flame should reach but does not reaches and causes efficiency of utilization low and heat the situations such as uneven, or flame oversize burning causes kiln refractory material to burn out on the breastwork of kiln opposite.
Fig. 1 is the structural representation of existing burner, and burner is mainly made up of oxygen burner 1 and fuel burner nozzle 2 two parts.Combustion gas enters from blast tube 3, and oxygen enters from the oxygen channel 4 between oxygen burner 1 and fuel burner nozzle 2, and both are in burner ejiction opening mixed combustion.When kiln temperature reach technique need time, the consumption of oxygen and combustion gas is basically unchanged, and combustion gas is constant at the flow velocity of the ejiction opening of fuel burner nozzle 2, and the flow velocity of combustion gas determines the length of flame, so the length of flame of burner is constant.
Utility model content
The purpose of this utility model be provide to solve the deficiency of above-mentioned technology a kind of oxygen, fuel gas supply amount keep constant in the case of the scalable pure oxygen combustor of adjustable flame length.
In order to achieve the above object, scalable pure oxygen combustor designed by this utility model, it includes oxygen burner and fuel burner nozzle, described oxygen burner is internal is oxygen channel, described fuel burner nozzle is internally provided with at least two blast tubes, and described oxygen channel is connected with oxygen feeding pipe, and described blast tube is at least divided into two groups, often group blast tube is connected with gas supply pipe by a pipeline, is at least provided with regulation valve on the pipeline being connected with one of which blast tube；Regulation valve is for regulating the ratio of the fuel gas supply amount in each blast tube.
Technique scheme, when normally producing, inventory and load are basicly stable constant, and kiln temperature needs stable to ensure melting quality.In the case of meeting kiln technological temperature stability contorting, the consumption of combustion gas is basically unchanged, the most if desired change the position of flame, then improve the combustion gas throughput in the most a certain group of blast tube by regulation valve, reduce the combustion gas throughput in remaining group blast tube simultaneously；Owing to the combustion gas throughput in one of which blast tube increases, then its flow velocity strengthens, it is thus possible to increase the length of flame, allows flame reach the position that kiln needs, preferably adds hot charge.When flame location is too remote, balance can be passed through by the combustion gas that regulation valve realizes often organizing in blast tube, then can reduce the flow velocity of combustion gas, it is achieved shorten the function of the length of flame.
