Abstract
A kind of high spraying speed gas burner mainly is suitable for usefulness such as blowing wool.It is characterized in that having adopted in this burner multistage coal gas induction apparatus, can suck enough coal gas, can produce high velocity air again.And to be prolate square for the bocca of the outlet of gaseous mixture nozzle and combustion chamber in this burner, novel and reasonable structure, thereby realized without the air compressor air feed, and only need common trailing plants thatch blower fan air feed, just can produce 200 meter per seconds and spray fast flame, have high, the advantages such as volume is little, in light weight, noise is low, economize on electricity of flame spray speed.
Description
The invention belongs to a kind of continuous flame coal air burner, be applicable to usefulness such as blowing wool.
The high spraying speed gas burner of prior art all be the compressed air of 0.3～0.8MPa air pressure of being produced with air compressor as combustion air, and in order to injection coal gas and produce at a high speed, its shortcoming is that power consumption is big, the production cost height, noise is big, and is bulky.
Purpose of the present invention is exactly that a kind of air pressure that is produced with trailing plants thatch blower fan will be provided only is that 0.015～0.25 air is a combustion air, and volume is little, noise is low, and significant high spraying speed gas burner economizes on electricity.
Technical scheme of the present invention is to adopt the method for multi-ejection coal gas, can suck enough coal gas and can produce certain air velocity again.The gaseous mixture nozzle adopts inlet, outlet to be rectangle and enters the mouth greater than the bucket shape structure of outlet, and the ejiction opening area is as the criterion with the mixing gas blowout speed that produces 30 meter per seconds.The shape of combustion chamber also is a prolate shape, and inlet and bocca are the square and area of prolate less than the basal area in the middle part of the combustion chamber.
Describe in detail below in conjunction with accompanying drawing:
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the A-A profile of Fig. 1;
Fig. 3 is the C-C cutaway view of Fig. 1.
As shown in Figure 1, high spraying speed gas burner of the present invention enters pipe (2) by gas mixeding cylinder (1), coal gas, adpting flange (3), air enter pipe (4), air nozzle (5) and gaseous mixture nozzle (10), combustion chamber compositions such as (12).Be characterized in that coal gas enters the axis normal of the axis and the gas mixeding cylinder (1) of pipe (2), air enters pipe (4) and air nozzle (5) and gas mixeding cylinder (1) coaxial line.First order coal gas is housed in gas mixeding cylinder coaxially sucks tube (6), second level coal gas suction tube (7), and in that being housed between gas mixeding cylinder (1) and the gaseous mixture nozzle (10), a gaseous mixture that has the narrow groove of lengthwise (9) on it stores cylinder (8), the narrow groove of aforesaid lengthwise (9) joins with the gaseous mixture nozzle, the axis of described cylinder (8) is identical with gas mixeding cylinder, and vertical with the center line of gaseous mixture nozzle (10) and combustion chamber (12).Gaseous mixture nozzle (10) is bucket-shaped (shown in accompanying drawing 1,3) in the present invention, and inlet and outlet are rectangle, and inlet area is greater than discharge area.Combustion chamber (12) is oblong (shown in an accompanying drawing 1,3), and to be prolate square for its inlet and bocca, and inlet, bocca area are less than the basal area in the middle part of the combustion chamber.Described combustion chamber (12) is to build up with refractory material (11), and other other parts of burner are all made with common iron or stainless steel.
10 kilowatts of Model machine manufactured according to the present invention adopts the trailing plants thatch blower fan air feed of, produce flame spray speed greater than 200 meter per seconds, and the burner volume is little, in light weight, and through certain mineral wool factory blowing wool, trial effect is good.
