Abstract
The invention belongs to the used for industrial furnace gas fuel burning apparatus.The industrial furnace that has requires the flame of burner short, and prior art can not meet the demands.The present invention adopts air and coal gas together to spray into to give the hybrid channel and carries out mixing, enters combustion chambers burn then, rotate simultaneously, and further mixing and accelerated combustion, so flame is short, coefficient of excess air is less, ignition temperature is higher.
The present invention can be used for the various industrial furnaces of requirement short-flame.
Description
The invention belongs to the used for industrial furnace gas fuel burning apparatus
Existing turbulent burner (" turbulent burner that is used for industrial furnace "-patent DE 2621496) is that the staggered many rows of air and coal gas enter the rapid mixing of mixing chamber by tangential and fore-and-aft tilt, enters combustion chambers burn then.This burner is compared with sleeve-type ceramic burner, and the length of flame can shorten 30～50%, and for the stove that requires short-flame (for example top combustion stove), the length of flame still is oversize, can not satisfy the needs of this class stove.
The present invention is intended to design the very short burner of a kind of flame, to satisfy the requirement to short flame burner such as top combustion stove, pebble stove.
Short flame ceramic burner of the present invention, as shown in the figure, it by combustion chamber 1, give hybrid channel 2, branch gas tube 3, air arm 4, coal gas endless tube 5, air endless tube 6 and form.The air arm is to be enclosed within the branch gas tube, and air and coal gas together spray into and gives the hybrid channel, and rapid mixing gives 40～80 ° of hybrid channel and combustion chamber radius extended line angles, with 40～90 ° of the axial angles of burner in giving the hybrid channel.Mist sprays into the combustion chamber and catches fire immediately from giving the hybrid channel, in the combustion chamber, rotates simultaneously, and further mixing and accelerated combustion in rotation, the length of flame is 0.5～2.0 times of combustion chamber internal diameter.
The outlet of short flame ceramic burner of the present invention has two kinds of tubaeform and cylindrical shapes, the flame flare of flaring exit, flame is short, forward momentum a little less than; The flame of garden tubular outlet is the garden cylindricality, and flame is long slightly, and forward momentum is stronger.
Short flame ceramic burner of the present invention is compared with " turbulent burner that is used for industrial furnace ": because coal gas and air flow velocity in giving the hybrid channel are higher, carried out preferably mixing, further mixing of rapid circular movement and accelerated combustion have been arranged after entering the combustion chamber again.So it is short to mix flame, coefficient of excess air is less, and ignition temperature is higher.
The present invention can be used for the various industrial furnaces of requirement short-flame.For example top combustion stove is that not only the furnace roof perforate has weakened the structural strength of furnace roof more with 2～4 sleeve-type ceramic burners now, and because flame is oversize, also in burning, makes the checker brick distortion, the shortening heat wind furnace life-span in regenerator.When top combustion stove adopts burner of the present invention, the short flame ceramic burner of available flaring exit, be installed in the positive center of hot-blast stove vault, burning vertically downward, burner generally equals 3～5 times of internal diameter of burner to the distance of regenerator, therefore flame does not reach regenerator, thus the life-span of having improved heating quality and having improved hot-blast stove.
Claims (4)
1, a kind of ceramic-lined burner is characterized in that: air and coal gas, and, together enter and give the hybrid channel through arm by endless tube, enter combustion chambers burn then.
2, according to claim 1 described burner, it is characterized in that: the air arm is enclosed within the branch gas tube, and air and coal gas together spray into and gives the hybrid channel.
3, according to claim 1 described burner, it is characterized in that: air and coal gas give the hybrid channel, with 40～80 ° of the extensions angles of combustion chamber radius, with 40～90 ° of the axial angles of burner.
