Abstract

The utility model relates to a pulverized coal and gas dual-purpose burner for industrial kiln belongs to industrial kiln burning firing equipment technical field. The technical scheme is that the burner comprises a burner shell, a coal powder inlet (1), a gas inlet (2), an air inlet (3), an air channel (6), a gas channel (7) and a coal powder channel (8), wherein the coal powder inlet and the gas inlet are arranged on the burner shell, the coal powder inlet is communicated with the coal powder channel, the gas inlet is communicated with the gas channel, and the air inlet is communicated with the air channel. The pulverized coal inlet and the pulverized coal channel penetrate through the axis of the burner shell, the gas channel is wrapped outside the pulverized coal channel, and the air channel is wrapped outside the gas channel. The utility model can realize the combustion of all gas fuel, all pulverized coal and the mixed combustion of gas fuel and pulverized coal according to the production requirement, and can share the same burner and simultaneously combust; the coal powder consumption is small, and the coal powder consumption is about 20-40 kg/h.

Description

Industrial kiln coal dust, gas two-purpose burner
Technical field
The utility model relates to a kind of industrial kiln coal dust, gas two-purpose burner, belongs to Industrial Stoves burning heating equipment technical field.
Background technology
At present, the widely used fuel of Industrial Stoves mainly is coal dust and combustion gas, and combustion gas mainly comprises blast furnace gas, coal gas of converter, calcium carbide tail gas etc., comprises that industrial waste gas reclaims gas; Coal dust mainly is that bituminous coal, anthracite reach 200 purpose coal dusts through the coal pulverizer fineness of grind, and current, fuel availability improves gradually, and alternately utilizing of various fuel proposed new requirement.The problem that background technology exists is: the burner function singleness, can only use coal dust or combustion gas separately, and can not realize that gaseous fuel and solid fuel (coal dust) burn simultaneously or change burning.
The utility model content
The purpose of the utility model provides a kind of industrial kiln coal dust, gas two-purpose burner, and realization gaseous fuel and solid fuel (coal dust) burn simultaneously or change burning, improve the utilization ratio of fuel, solve the problems referred to above that background technology exists.
The technical scheme of the utility model is: industrial kiln coal dust, gas two-purpose burner; Comprise burner shell, be arranged on coal dust import and fuel gas inlet and air intlet on the burner shell, be arranged on air duct and blast tube and coal dust passage in the burner shell; Coal dust import and coal dust channel connection; Fuel gas inlet is communicated with blast tube, and air intlet is communicated with air duct.
Coal dust import and coal dust passage run through on the axis that is arranged on burner shell, and blast tube is wrapped in coal dust passage outside, and air duct is wrapped in the outside of blast tube.
Between air intlet and air duct, be provided with air guiding device, air is a rotating operation through behind the air guiding device with the burner shell axis.
Exit at air duct, blast tube, coal dust passage is provided with the shield body, and the shield body is arranged on the axis of burner shell, and the shield body is the export orientation device of coal dust, combustion gas, can regulate the length of flame.
The shield body of background technology coal burner is regulated at afterbody through pull bar, to obtain the desirable length of flame (angle).The fixed form of the utility model shield body is: the tube wall welding of shield body and coal dust passage is fixing, regulatory function before and after the cancellation.Former pull bar passage changes the coal dust passage into, and former coal dust channel space increases by a pipeline as gas passage, and air duct is still in outermost, and the reservation air guiding device is to realize air rotation output.
The good effect of the utility model is: the utility model can be realized full gas fuel combustion, full coal dust firing, gaseous fuel and coal dust mixed combustion according to the production needs, and can shared same burner, burn simultaneously; Coal consumption is little, and the coal dust consumption is about 20-40Kg/h.
Description of drawings
Accompanying drawing 1 is the utility model embodiment sketch map;
Among the figure: coal dust import 1, fuel gas inlet 2, air intlet 3, air guiding device 4, shield body 5, air duct 6, blast tube 7, coal dust passage 8.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further specified through embodiment.
Industrial kiln coal dust, gas two-purpose burner; Comprise burner shell, be arranged on coal dust import 1 and fuel gas inlet 2 and air intlet 3 on the burner shell, be arranged on air duct 6 and blast tube 7 and coal dust passage 8 in the burner shell; Coal dust import and coal dust channel connection; Fuel gas inlet is communicated with blast tube, and air intlet is communicated with air duct.Coal dust import and coal dust passage run through on the axis that is arranged on burner shell, and blast tube is wrapped in coal dust passage outside, and air duct is wrapped in the outside of blast tube.
Between air intlet and air duct, be provided with air guiding device 4, air is a rotating operation through behind the air guiding device with the burner shell axis.Exit at air duct, blast tube, coal dust passage is provided with shield body 5, and the shield body is arranged on the axis of burner shell, and the shield body is the export orientation device of coal dust, combustion gas, can regulate the length of flame.The tube wall welding of shield body and coal dust passage is fixing.The shared same air duct of coal dust and combustion gas.
Sparking mode: coal gas and air mixed combustion mode are lighted a fire, and when burning indoor temperature coal supply powder when reaching the coal dust firing condition, close after the coal dust completing combustion or reduce the coal gas quantity delivered.
