Abstract
The utility model relates to a gas combustor. A first stage wind distribution is in a separate type, and a second stage, a third stage and a fourth stage wind distributions are in an integral type. A combustion spray head with a plurality of holes prevents gas fuel from being immediately combusted after sprayed, the gas fuel is caused to be fully mixed with air, the gas combustor does not form coking, the fuel ratio is automatically regulated, and the fuel is fully combusted. The utility model can be broadly used for industrial heating furnaces.
Description
The utility model relates to a kind of burner, particularly the burner of burning gases fuel.
The burner of current combustion gaseous fuel, version is varied." the secondary gaseous mixture burner " that China Patent No. 93223642.1 is invented, be provided with two mixing chambers, first mixing chamber is made up of nozzle, nut, accent wind lid, fixed head, central tube and shell, is drilled with numerous fresh air inlet respectively on central tube, accent wind lid and the fixed head.Second mixing chamber is made up of central tube and investigation mission outside the city or town blast cap and shell and extension housing, and shell is drilled with numerous fresh air inlet in position.This burner structure complexity, burning gases and air undercompounding, impracticable on the large scale industry heating furnace.
The purpose of this utility model is a kind of burner simple in structure of design, and in this burner, burning gases can fully mix with air, the large-scale gas burner that can use on industrial heating furnace.
The purpose of this utility model is to implement like this:
Be drilled with a plurality of gas spray orifices on the gas nozzles (1), the place ahead of each gas spray orifice (6) is provided with corresponding one-level blower cover (4), front end at the one-level blower cover is provided with multistage blower cover in turn, blower cover inner chambers at different levels amplify step by step, be provided with certain space between gas spray orifice (6) and the one-level blower cover, combustion air is entered by the rear portion of blower covers at different levels in turn, mixes in each blower cover step by step with combustion gas.The inner chamber of blower covers at different levels amplifies step by step, and one-level blower cover air distribution is an isolated, and secondary, three grades and level Four blower cover air distribution are monoblock type.
The utility model has the advantages that: this burner structure is simple, can be provided with a plurality of gas spray orifices in each burner, and flame is short, and thermic load is big.Can be used in the industrial heating furnace, to enter the direction of each blower cover be consistent with the flame combustion direction to air in addition, can make the flare flameholding, fuel combustion is abundant, has avoided the ejection of gas nozzles (1) gaseous fuel promptly to fire the overheated coking that is caused, the defective of stopping up shower nozzle.

Among Fig. 4 A--A cutaway view figure: 1. 8. 3 grades of blower covers of gas nozzles 2. gusset A, 3. secondary blower cover 4. one-level blower covers, 5. gusset B 6. gas spray orifices, 7. gusset C, 9. level Four blower covers, 10. gusset D, 11. shells, 12. gusset E, 13. gusset F, 14. bases, 15. connecting plates.
Introduce the utility model in detail below in conjunction with accompanying drawing:
Gas nozzles (1) are connected with secondary blower cover (3) rear end and fixing through gusset (2); One-level blower cover (4) is connected with the rear end inwall of secondary blower cover (3) and fixing through gusset (5); Base (14) is connected with the outer wall of gas nozzles (1) and is fixing; The centerline of the spray orifice (6) of the center line of one-level blower cover (4) and gas nozzles is in same center line, and the rear end inwall of three grades of blower covers (8) is connected with the front end outer wall of secondary blower cover (3) and fixing through gusset (7); The inwall of level Four blower cover (9) rear end is connected with three grades of blower covers (8) front end outer wall and fixing through gusset (10); Shell (11) is connected with gusset (12), gusset (13), base (14) respectively and is fixing; Connecting plate (15) is installed on the outer wall of the 4th blower cover (9) and with gusset (12) and is connected and fixed; Shell has numerous fresh air inlet on (11), and the inner chamber of secondary, three grades and level Four blower cover amplifies step by step.Gas nozzles (1) are hollow container, and the lower end is the gas import, and the upper end is provided with a plurality of gas spray orifices (6), leave the space between one-level blower cover (4) and the gas spray orifice (6).So that air is under the negative pressure of the stylish formation of methane injection of high velocity stream, air sucked in the one-level blower cover mix with gas, after gas that ejects in the one-level blower cover and air gas mixture enter the secondary blower cover, air is sucked by the space between burner postmedian and the gusset (5) and fully mixes with mist, and mist enters three grades of blower covers and level Four blower cover successively.Flame generally burns in three grades of blower covers, and air is constantly entered respectively in the blower covers at different levels by the space between gusset (2), gusset (5), gusset (7), the gusset (10), through multistage mixing, can make Device in Gas completing combustion.This burner one-level blower cover air distribution is an isolated, and secondary, three grades and level Four air distribution are monoblock type.
Claims (3)
- A kind of nondestructive inspection gas burner, comprise gas nozzles (1), shell (11), connecting plate (15) etc., it is characterized in that being drilled with on the gas nozzles (1) a plurality of gas spray orifices (6), the place ahead of each gas spray orifice (6) is provided with corresponding one-level blower cover (4), front end at the one-level blower cover is provided with multistage blower cover in turn, and the inner chamber of blower covers at different levels amplifies step by step.
- 2. according to the described burner of claim 1, it is characterized in that combustion air is entered by the rear portion of blower covers at different levels in turn, in blower covers at different levels, mix step by step with combustion gas.
- 3. according to the described burner of claim 1, it is characterized in that the one-level blower cover air distribution of burner is an isolated, secondary, three grades and level Four blower cover air distribution are monoblock type.
