Abstract
The utility model discloses a combustion beam for a lime kiln. A fuel pipeline and a combustion-supporting air pipeline are arranged in a beam body, the outlets of the fuel pipeline and the combustion-supporting pipeline are connected with nozzles arranged on the side wall and the bottom of the beam body, and the fuel pipeline and the combustion-supporting pipeline of the beam are divided into an upper layer and a lower layer to independently control the combustion of the nozzles of the upper and lower layers respectively. The combustion beam fulfills the purposes of effective control of the combustion temperature and uniformly distributed combustion of the fuel in the kiln by separately controlling the air-fuel ratio at the nozzles of the upper and lower layers so as to greatly reduce the combustion temperature near the combustion beam and combust lime in the whole lime kiln more uniformly.
Description
Technical field
The utility model relates to the burning beam that a kind of limestone kiln is used.
Background technology
During with the beam-type limekiln calcined limestone, raw materials such as Wingdale are added installing in the limestone kiln from the top, raw material is from top to down through preheating district, calcining zone, cooling zone, then from the products export output.Be provided with burning beam in the calcining zone, burning beam is the nucleus equipment of beam-type limekiln, and its cross section is generally the cavity structure of rectangle or T type, is loaded with combustion agent and heat-eliminating medium in the cavity.The beam body of burning beam is provided with burner, fuel conduit and combustion air pipeline, fuel conduit and combustion-aid air pipe road direction burner fuel supplying and combustion air, and burner uniform distribution fuel also burns.
The limestone kiln is in burning process, in burning beam when burning, is because fuel is more abundant in the burning of burner place, temperature is higher near causing burning beam, particularly near the temperature the burner is too high, make kiln body heat content skewness, long-time running will cause the reduction in burning beam life-span and the reduction of Wingdale output.And having near the lime burning of burning beam, lime at a distance still has part to give birth to the generation of burning phenomenon.
The utility model content
It can be uniform heat distribution in the limestone kiln that the utility model technical issues that need to address provide a kind of, the burning beam that the limestone kiln in raising limestone kiln life-span is used.
For solving the problems of the technologies described above, technical solution adopted in the utility model is:
The burning beam that a kind of limestone kiln is used, comprise the beam body, in the beam body air delivering pipeline is set, air delivering pipeline comprises fuel conduit and combustion air pipeline, the outlet meet of the outlet of fuel conduit and combustion air pipeline is provided with burner, the intravital air delivering pipeline of described beam is arranged to two-layer up and down, is provided with interlayer between the levels, and the exit of every layer of air delivering pipeline is provided with burner.
Improvement of the present utility model is: be respectively arranged with row's burner on the left and right sides sidewall of described beam body, burner is connected with the outlet of upper strata air delivering pipeline; The bottom of beam body is provided with row's burner, and this burner is connected with the outlet of lower floor's air delivering pipeline.
Improvement of the present utility model is that described beam external surface is coated with the thermal boundary pottery.
Improvement of the present utility model is, described beam body is wide at the top and narrow at the bottom trapezoidal.
Improvement of the present utility model is that each face junction of described beam external surface is round-corner transition.
Owing to adopted technique scheme, the obtained technical progress of the utility model is:
The intravital air delivering pipeline of burning beam beam is divided into two-layer setting, can effectively regulate the air-fuel ratio of interlayer, is guaranteeing that it is more that the upper strata pipeline can be arranged to combustion gas under the constant prerequisite of total air-fuel ratio, and it is more that lower floor then is arranged to air; Perhaps to be arranged to air more for the upper strata pipeline, and it is more that lower floor then is arranged to combustion gas; The fuel that this kind air-fuel ratio is provided with is behind burner combustion, must cause the upper strata to remain a large amount of combustion gas or air, lower floor then remains a large amount of air or combustion gas, this moment, unnecessary other directions of gas phase flowed, when when meeting away from other positions of burning beam, can burn voluntarily, thereby realization reduces near the purpose of the temperature of burning beam, make that also the lime burning in the limestone kiln is more even.When the utility model was applied to the limestone kiln of fuel of high heating value, effect was more obvious.
Be coated with the thermal boundary pottery at the beam external surface, can play thermal resistance, anti-oxidant operation, the effect that reach energy-conservation, increases the service life.The beam body is designed to wide at the top and narrow at the bottom trapezoidal, can reduces Wingdale, increase the service life the washing away of beam body.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further details:
Fig. 1 is the burning beam that a kind of limestone kiln is used, and comprises beam body 1, is provided with two-layer air delivering pipeline in the beam body, is provided with interlayer 5 between the two-layer air delivering pipeline.Every layer of air delivering pipeline includes fuel conduit 2 and combustion air pipeline 3; Be respectively arranged with row's burner 4 on the left and right sides sidewall of beam body, burner is connected with the outlet of air delivering pipeline; The bottom of beam body is provided with row's burner, and this burner is connected with the outlet of lower floor's air delivering pipeline.Beam body 1 is designed to wide at the top and narrow at the bottom trapezoidal.Simultaneously, can be coated with the thermal boundary ceramic layer at the beam external surface.
In the present embodiment, when the air-fuel ratio of combustion gas and air is provided with, under the constant prerequisite of the overall air-fuel ratio that guarantees whole burning beam, adopt the bigger ratio of combustion gas proportion in the air delivering pipeline of upper strata, lower floor then is arranged to the bigger ratio of air specific weight.The mode that this kind air-fuel ratio is provided with, the gas after will inevitably causing the upper strata through burning will have unnecessary combustion gas and discharge burning beam, lower floor then have many and air discharge.Will be after unnecessary gas is discharged in the burning of meeting away from other positions of burning beam, thus other lime away from burning beam in the kiln are burned.Greatly reduce near the temperature of combustion the burning beam, also solved the kiln sodalime uniform problem of burning simultaneously.
