The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in further detail.
Shown in Fig. 1 ~ 4, hydrogen gas combustor comprises central passage 1, the center-aisle 2 outside the centering passage 1 that is positioned at the axle center and places the outer outer ring channel 3 of center-aisle, central passage 1 is nitrogen or air purge passage, the rear portion of central passage 1 is provided with nitrogen or air intake 11, when being used for the long period blowing out, being filled with nitrogen or air in the burner hearth by this passage and being trapped in remaining fuel gas in the burner hearth with displacement; Center-aisle 2 is the hydrogen passage, and a side of center-aisle 2 is provided with hydrogen inlet 21; Outer ring channel 3 is air duct, and the front end of outer ring channel 3 is provided with enlarging flame tube 301, and the structure of enlarging shape plays the effect that changes air flow direction, and to shorten the length of flame, outer ring channel 3 one sides are provided with air intake 31.Stable flame pan 4 is arranged on the front portion of outer ring channel 3, stable flame pan 4 comprises close up section 401 and flared section 402, section 401 and the flared section 402 of closing up all is taper type, the small end of the section 401 that closes up is connected with the small end of flared section 402, the small end of flared section 402 is provided with a plurality of passages 403, and the large end of flared section 402 is provided with the eddy flow guiding grooving 404 of a plurality of even settings.The front end of central passage 1 and center-aisle 2 is arranged in the closing in section 401 of stable flame pan 4, and central passage 1 and center-aisle 2 front ends are all open-minded, are communicated with stable flame pan 4; The front end of center-aisle 2 is provided with the section 201 that closes up, the outer wall of central passage 1 front portion is provided with choke ring 202, choke ring 202 is positioned near the port of export of center-aisle 2, that is to say choke ring 202 in the inboard of the closing in section 201 of center-aisle 2, consist of an air annular space 203 between the outer wall of center-aisle 2 closing in sections 201 and the closing in section 401 of stable flame pan 4.The front portion of center-aisle 2 is connected with the jet pipe 5 of a plurality of even settings, and the spout 501 of jet pipe 5 is pressed close to the outer wall of stable flame pan flared section 402, and spout 501 places of jet pipe 5 are provided with the angular cut towards stable flame pan flared section 402 outer walls.Igniter 6 is arranged in the outer ring channel 3, and the ignitron 601 of igniter 6 connects the flared section 402 of stable flame pan 4, and the rear side of igniter 6 is provided with liquefied gas or gas inlet 61.
In use, hydrogen enters center-aisle 2 by hydrogen inlet 21, be divided into two-way: fraction sprays into stable flame pan 4 by center-aisle 2 front ends, because the closing in section 201 of center-aisle 2 and the effect of choke ring 202, only make the hydrogen of fraction spray into stable flame pan 4 from middle passage 2 front ends, this part hydrogen with via air annular space 203, the air that passage 403 on the stable flame pan 4 and eddy flow guiding grooving 404 enter stable flame pan 4 fully mixes, air annular space 203, passage 403 and eddy flow guiding grooving 404 can effectively be organized mixing of air and hydrogen, makes and is formed centrally the stable flame that rotates in the stable flame pan; Most of hydrogen is by jet pipe 5 ejections, spout 501 places of jet pipe 5 have adopted the structure of cutting sth. askew, play the effect of water conservancy diversion, make hydrogen injection to the outer wall of the flared section 402 of stable flame pan 4, become the hydrogen stream of thigh to scatter in the outer wall shop of stable flame pan 4 flared section 402, then with air with certain angle of intersection, after the full and uniform mixing, between the enlarging flame tube 301 of the outer wall of stable flame pan 4 flared section 402 and outer ring channel 3 front ends, spray into hearth combustion.
The adjusting of the burner design of combustion of hydrogen of the present invention is 1/4 of rated output power at the burner minimum output power namely than for 1:4.The flame propagation velocity of combustion of hydrogen very large (2.75m/s), under the minimum output power operating mode, the muzzle velocity of hydrogen is greater than the flame propagation velocity of combustion of hydrogen, thereby rationalization's flow field structure, guarantee that hydrogen can completing combustion, the length of flame is controlled at again within the rational scope, effectively prevents the generation of underload tempering phenomenon.
Igniter 6 centers in the outer ring channel 3 are provided with ignitor, the electric spark that utilizes electrion to produce is lighted liquefied gas or natural gas, and liquefied gas or flaring pass into hydrogen after successfully setting up, hydrogen is lighted and smooth combustion by liquefied gas or flaring with after air mixes.
Before hydrogen enters hearth combustion, mix by stable flame pan 4 and air are full and uniform, spray into hearth combustion after reaching the mixed effect of design, the flame of combustion of hydrogen is about 1/2nd of furnace height, can guarantee that overheating problem does not occur boiler back end ductwork, guarantee the stable operation of boiler long-term safety.
