The specific embodiment:
Below in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4, the utility model is further explained:
In the present embodiment; The utility model comprises burner shell, flame-thrower nozzle, circulation of air airduct, demand in dicator and five main parts compositions of peripheral hardware link gear; For the goal of the invention that realizes the utility model is provided with demand in dicator on air supply pipe, the air intake branch front end forms three air intake branches and together is connected annular nozzle; The shower nozzle rear side is provided with the removal of impurities mouth; The annular nozzle center is provided with the air swirl sheet, and described air swirl sheet maskable falls refined zone, guarantees the stability of flame.The circulation of air airduct that is used to participate in burning is made up of first and second air duct; Wherein an air duct is responsible for participating in burning for the first time, and secondary air duct front end is provided with uniform wind complement port, realizes that the blending second time after the primary combustion is burnt; All the other air quantity of secondary air duct can continue the oxygenating burning along the flame propagation direction; Make sufficient combustion, flame is even, is provided with the external automatic control blowing system that adjusting yoke or travelling gear are used to realize burner in the hull outside of secondary air duct.One time air duct all is respectively equipped with 6 circulation areas, opening shape, big or small all identical rectangle air port with the secondary air duct; Tuyere position is evenly distributed on the circumference of two air ducts; But the air port circulation area on the air duct separately is different; Promptly the air distribution amount is different with secondary air distribution amount supply next time with gas quantity; Use contiguous block between two air ducts and carry out fixed ratio, realized the proportional interlock of first and second air duct, when opening contiguous block, can realize the independent conciliation of burner first and second air distribution amount according to certain excess air coefficient; Be provided with dismountable end plate before the air duct, on the end face of end plate, be provided with glory hole, flame detector installing hole and igniter installing hole.When reconciling flame, operating personnel can carry out the load up-down control adjustment of burner through the observation demand in dicator; The air distribution adjustment that correspondence is adjusted once simultaneously, the secondary air duct is realized burner; The fixed position of first and second air duct is demarcated by professional saving energy test mechanism Application Major instrument, realizes that the air distribution amount of burner makes the flue gas excess air coefficient maintain between 1.05～1.15 scopes in the whole process that interlock is reconciled all the time.
The numeral that the pointer of demand in dicator indicates is total thermal discharge Q of gas quantity that this burner passes through; According to fluid mechanics principle; This total thermal discharge Q be one with combustion gas calorific capacity q, by the discharge coefficient μ of fumarole structure decision, all relevant function of gaseous-pressure p, i.e. Q=f (q, μ, dp, γ, p) before the equivalent diameter dp, combustion gas severe γ, spray orifice of fumaroles.The burner of design under certain rigid condition, the q in its following formula, μ, dp, γ can be fixed numeric values, are variable numerical value and have only p, therefore, under this condition, total thermal discharge Q just only with spray orifice before pressure p relevant, i.e. Q=f (p).According to this formula, through calculating the relation can obtain Q and p, and be plotted to the pairing Q value of p on the manometric dial plate of the prior art, just become demand in dicator.So just can be directly directly read the total thermal discharge of combustion gas of this burner from the demand in dicator.Demand in dicator belongs to the general demand in dicator of the present industry.
At first with 3 gas manifolds 201 of burner air supply pipe 200 front end welds; And with arm connection and burner tip 300 welding; And annular nozzle got the gas jet orifice 303 of some; Again air swirl sheet 301 welded and installed are installed in the rear side of shower nozzle at annular nozzle 300 zone lines, shower nozzle removal of impurities mouth 302, the flame-thrower nozzle of such burner is just assembled and has been accomplished, and the air supply pipe 200 of above-mentioned processing is passed to the left the drive end bearing bracket of an air duct 400 subsequently by the right side again; After adjusting to certain distance fuel pressure measuring valve 101 is installed on the air supply pipe 200, again demand in dicator 100 is installed on the pressure measuring valve 101 afterwards.Secondly; An air duct 400 of burner, secondary air duct 600 manufacturing process are to be processed the drum of certain diameter by certain thickness roll of steel plate; On cylinder, leave primary air nozzle 402 and overfiren air port 602; Again air duct 400 left side 2-3cm are encircled and be provided with 6 end cap holding screw holes in all zones; The right side of an air duct 400 is connected through the left side of contiguous block 500 with secondary air duct 600, wherein is provided with 6 air duct gap pulleys 601 in the ring of the left side front end 3-5cm of the secondary air duct 600 week zone, and the ring of 3-5cm is provided with 2 row's secondary wind premix mouths 603 on week in the rear end, right side; Primary air nozzle 402 and overfiren air port 602 need fix the installation site of two air ducts according to certain corresponding ratio during installation; Second again peripheral hardware connecting rod 700 is welded on the secondary air duct 600 after connecting, can realizes the external automation control of burner, after one time air duct 400 is connected completion with secondary air duct 600; To be fixed on 1/2nd places of secondary air duct 600 again with the identical a slice mounting flange 800 of fire door size; Then flange crimping piece 801 is crimped on the flange, utilize crimping piece holding screw 802 with flange together with once being fixed on the heating furnace 900 with the secondary air duct, the air duct of burning is on the centermost line of heating furnace annular tile 901.At last, the complete nozzle that has an air duct end cap that will assemble again inserts and is fixed in the burner object on the heating furnace, and utilizing end cap holding screw 401 is that end cap is connected with an air duct, has so just accomplished the assembling process of burner.
