Abstract
A coal gas combustion tube of a radiation furnace comprises a coal gas tube, a protective body on the coal gas tube, a connecting plate connected with the upper end of the coal gas tube, a smoke box connected with the connecting plate, a thermal insulation device in the smoke box, an igniter connected with the smoke box, a coal gas hole in the igniter, an ignition hole and a nozzle at the lower end of the gas pipe. The combustion tube is characterized in that the ignition hole is formed in the coal gas tube above the nozzle; the length of the gas pipe is not less than 400 mm. The condition of the coal gas combustion tube deformation due to the heating can be greatly reduced; the length of the tube through which the coal gas goes after the ignition is reduced; the temperature of the coal gas tube is reduced; so that the service cycle and the unit operating rate are improved; the maintenance cost and the production cost are reduced; the implementation is very easy.
Description
Technical field
The utility model relates to a kind of combustion tube, specifically belongs to a kind of gas burning pipe of all-radiant furnace.
Background technology
At present, the gas burning pipe of all-radiant furnace is because topology layout is unreasonable, is located at the igniter place as the coal gas ignition hole, makes the coal gas pass course after igniting long, causes gas pipe to be out of shape owing to being heated, need often in time to change, thus normally carrying out of guaranteeing to produce.This makes normal production of enterprise be affected, and maintenance cost and production cost strengthen, and the unit operation rate reduces.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and a kind of situation that can significantly reduce being heated of gas burning pipe and be out of shape is provided, and improves the gas burning pipe of the all-radiant furnace of life cycle and unit operation rate.
Realize the technical measures of above-mentioned purpose:
A kind of gas burning pipe of all-radiant furnace, the nozzle of the Thermal packer in the connecting plate that is connected by the protective on gas pipe, gas pipe, gas pipe upper end, the flue gas case that is connected with connecting plate, flue gas case, the igniter that is connected with the flue gas case, the gas vent on igniter, fire hole, gas pipe lower end forms, and it is: fire hole is arranged on gas pipe more than nozzle; The length of gas pipe is not less than 400 millimeters.
Characteristics of the present utility model are: can significantly reduce gas burning pipe and produce the situation of distortion because being heated, reduce the siphunculus length of the rear coal gas of igniting, reduce the temperature of gas pipe, thereby improve life cycle and unit operation rate, and reduce maintenance cost and production cost, very easily implement.
Description of drawings
Fig. 1 is structural representation of the present utility model;
In figure: 1-gas pipe, 2-protective, 3-connecting plate, 4-flue gas case, 5-Thermal packer, 6-igniter, 7-gas vent, 8-fire hole, 9-nozzle.
The specific embodiment
Be described further below in conjunction with accompanying drawing:
A kind of gas burning pipe of all-radiant furnace, by length be not less than the interior Thermal packer 5 of connecting plate 3, the flue gas case 4 that is connected with connecting plate 3, flue gas case 4 that the gas pipe 1 of 400 millimeters, protective 2, gas pipe 1 upper end on gas pipe 1 connect, the igniter 6 that is connected with flue gas case 4, the nozzle 9 of gas vent 7, fire hole 8, gas pipe 1 lower end on igniter 6 forms.For realizing its purpose, it is arranged on fire hole 8 on the gas pipe 1 of nozzle more than 9, thereby due to the distance of passing through that has shortened the rear coal gas of igniting, and the operating temperature of gas pipe 1 is reduced, the situation of being out of shape because being heated is eliminated substantially, and its life cycle is improved, and maintenance cost reduces.
What gas pipe 1 adopted the high-temperature alloy material is best.
The structure of gas-fired another gas burning pipe wherein in all-radiant furnace all is same as structure of the present utility model.
The specific embodiment of the present utility model is only for exemplifying, and non-limiting enforcement.
