Mostly the burning beam of prior art is the single fuel firing beam, a kind of fuel that can only burn, or geseous fuel or solid fuel.The burning beam of single-fuel can not adapt to the switching of fuel, and especially the quality of fuel changes, and calorific value does not reach when requiring, and the burning beam of single-fuel can not satisfy the needs of calcining materials, causes the calcination product quality to reduce.
Summary of the invention
For overcoming the deficiency of above-mentioned prior art; The utility model provides a kind of limestone kiln to use the compound combustion beam; Can using gas fuel or solid fuel calcine, can calcine with gas and two kinds of fuel of solid simultaneously again, improve the use properties and the flexibility of operation of burning beam.
The compound combustion beam is used in the utility model limestone kiln, is made up of beam body, burner and T female cap.Burner is positioned at the both sides and the bottom of beam body, and the beam body is provided with the cavity of thermal oil circulation, and outlet is connected the cavity of thermal oil circulation with thermal oil with the thermal oil inlet.Beam body inner route clapboard is divided into upper and lower two portions, and the top of beam body comprises blast tube, goes up combustion air passage and combustion gas spout, and blast tube is connected with the combustion gas spout, the burner of the corresponding beam body of combustion gas spout both sides.The lower section of beam body is provided with coal dust pipeline, coal dust spout and following combustion air passage, and the coal dust pipeline is connected with the coal dust spout, the burner of the corresponding beam body of coal dust spout bottom.
Beam body both sides are respectively equipped with 5～15 burners, and beam body bottom is provided with 5～15 burners.The burning beam external is equipped with the wear resistant heat preserving layer.Dividing plate is provided with the support that supports blast tube.
The compound combustion beam is used in the utility model limestone kiln, through dividing plate burning beam beam body is divided into two portions, and top is fuel gas buring equipment; The bottom is a coal-dust combustion device, can select to use separately upper gas fuel combustion or bottom coal dust firing, also can select using gas fuel combustion simultaneously and coal dust firing; Increased the flexibility of operation of burning beam; Improve the burning beam use properties, helped increasing the working ability in limestone kiln, improved the lime product quality.
Description of drawings
Fig. 1 is the structural representation of the utility model limestone kiln with the compound combustion beam.
Wherein: the outlet of 1-thermal oil, 2-T female cap, 3-burner, 4-blast tube, 5-support, 6-coal dust pipeline, 7-coal dust spout, 8-combustion gas spout, 9-last combustion air passage, 10-thermal oil inlet, 11-dividing plate, 12-following combustion air passage, 13-beam body.
Embodiment
Below in conjunction with accompanying drawing the utility model is done further explanation.
The compound combustion beam is used in the utility model limestone kiln, and is as shown in Figure 1, is made up of beam body 13, burner 3 and T female cap 2, and said burner is positioned at the both sides and the bottom of beam body, and it is 10 burners that every side is provided with, and the bottom is provided with 10 burners.The beam body is provided with the cavity of thermal oil circulation; The cavity of thermal oil circulation is connected with thermal oil outlet 1 with thermal oil inlet 10; The entrance and exit of thermal oil is connected with the thermal oil recycle system, is used for cooling combustion beam beam body, avoids high temperature to burn out equipment in burning beam and the beam body.Beam body inner route clapboard 11 is divided into upper and lower two portions.The top of beam body comprises blast tube 4, goes up combustion air passage 9 and combustion gas spout 8, and dividing plate is provided with support 5, is used to support blast tube 4.Blast tube is connected with the combustion gas spout, the burner 3 of the corresponding beam body of combustion gas spout both sides.Blast tube is connected with beam body 13 outside gas lines, and last combustion air passage is communicated with burner in the beam body, is connected with gas blower through pipeline in the beam external.The lower section of beam body is provided with 10 coal dust pipelines 6, coal dust spout 7 and following combustion air passage 12, and the coal dust pipeline is connected with the coal dust spout, the burner 3 of the corresponding beam body of coal dust spout bottom.The coal dust pipeline is connected with the external coal dust supply line of beam, is communicated with burner in the following combustion air passage 12 beam bodies, is connected with gas blower at the external pipeline that passes through of beam.The wear resistant heat preserving layer is equipped with in burning beam beam body 13 outsides, is used to protect the beam body, reduces material, flue gas and dust to the abrasion of beam body, avoids high temperature to burn out the beam body.
The utility model limestone kiln uses the operation scheme of compound combustion beam to do; On beam body top; Combustion gas gets into beam body top blast tube 4 through gas line, is ejected into burner 3 through combustion gas spout 8, and gets into the air mixed of burners through last combustion air passage 9 and burns.In beam body lower section, coal dust is through coal dust pipeline 6, coal dust spout 7 ejection coal dusts, and gets into the air mixed of burner and burns through combustion air passage down.
According to the production needs, can select independent using gas fuel combustion or coal dust firing, also can select using gas fuel combustion simultaneously and coal dust firing, flexibility of operation is good.
