The specific embodiment
Below be described in detail with reference to the accompanying drawings, when the present invention is elaborated,, then omit detailed description for it if the specific descriptions of dependency structure and function are had the opposite effect to the present invention on the contrary.
Fire-boosting device for gas furnace of the present invention comprises by a side gas conduct pipe 111, spray the burner 110 of several nozzles 112 compositions of combustion gas through gas conduct pipe 111, the combustion gas of nozzle 112 ejections by burner 110 inboards and air blast 123 provide the air of the air supplying part that the spray-hole 122 of air constitutes to mix the flame ignition portion 100 of back formation mutually, the firepower that flame is focused on shell 210 formations of central part is concentrated portion 200, the flame that firepower concentrates portion 200 to be discharged passes to heating chamber 322, the enhancing firepower portion 300 of boiler clothing 320 formation in the eddy current radiant heat of the inhibition exhaust bracket 321 collision back generations on flame and interior boiler clothing 320 tops heats at this moment.
Above-mentioned flame ignition portion 100 supplies with by producing flame that air supplying part 120 that the fuel of the burner 110 of fuel and burner 110 ejections obtain pressure-air forms.
Above-mentioned burner 110 is rounded, and the one side is connected with gas conduct pipe 111, and the nozzle of upper end periphery is radial arrangement towards ventilator cowling 121 directions.
Above-mentioned air supplying part provides the air blast 123 of air to form by the ventilator cowling 121 that has air jet hole 122 with by air jet hole 122.
The flame that burner ventilator cowling 121 and burner nozzle 112 spray meets and makes flame upwards, and cavity 121a and at least more than one airport platform 121b are arranged in it, and each airport platform 121b is surrounded with several air jet holes 122.
Air blast 123 provides the feed path of air to be connected with the air-supply conduit 123a of the fan that is assembled in air blast with wind-guiding fan blow out air for the cavity of ventilator cowling 121.
It is that flame for ejection focuses on the center of top position and produces powerful firepower and be provided with that above-mentioned firepower is concentrated portion 200, and there is flame export 211 at its shell 210 centers, in the bottom of flame export 211 up-narrow and down-wide inclined plane 212 are arranged.In shell 210 bottom group are contained in the boiler clothing backing ring 220 on the interior boiler clothing backing rings retaining platforms 221 in week, boiler clothing 320 in the top arrangement of interior boiler clothing backing ring 220, and be fixed in the inboard of the outer boiler clothing 310 of burner 110 upper ends.
The angle on the burner shell inclined plane 212 of shell 210 is advisable with 30～45 degree.
The shell fixing hole 213 of shell 210 bottoms and 113 assemblings of a bucking a rivet of the even five equilibrium in burner 110 upper ends, burner supporting plate 132 holders of burner 110 bottoms are on the firm banking bolt 131 on firm banking 130 surfaces.Can adjust the setting height(from bottom) of burner 110 by the length of adjusting firm banking bolt 131, so that adjust heating chamber and firepower increase and decrease effect, the outside of burner supporting plate 132 is clipped to outer boiler clothing 310 be suitable for the relatively more suitable setting height(from bottom) of adjustment according to combustion gas kind of using and pressure.
This strengthen flame ignition portion 100, inboard, upper end that firepower portion 300 comprises that outer boiler clothing 310 surrounds into heating chamber 322 that the interior boiler clothing 320 that suppresses exhaust bracket 321 constitutes is set, be arranged in the flame drain tank 331 of 400 of frying pans of the pot bracing ring 330 of boiler clothing 320 upper ends and placement.
Outer boiler clothing 310 is cylindrical, and the bottom is arranged on the bottom of burner 110, and its upper end separates with a pot bracing ring 330 to be set spacing and be arranged on a pot bracing ring bottom, to prevent pot bracing ring 330 direct heat transfers.
Interior boiler clothing 320 is cylindrical, top interval setpoint distance with burner 110, do not give heat conduction above the interior boiler clothing backing ring 220, interior boiler clothing 320 upper ends are provided with the inhibition exhaust bracket 321 of circulating type, make the flame of discharging in the heating chamber 322 directly not be ejected into the flame drain tank 331 of pot bracing ring 330, heat interior boiler clothing 320 with the flame that is collided and form eddy current.
In order to prevent that the heat of heating chamber passes to shell in the stove, filling with insulation material 340 in the cavity between boiler clothing 310 and the interior boiler clothing 320 outside, interior boiler clothing 320 exceeds a joint than outer boiler clothing 310, and the part of protrusion is placed a pot bracing frame 330.
Further specify as follows to structure of the present invention:
Gas conduct pipe 111 is connected with the fuel supplying pipe, open the supply valve, combustion gas is introduced in burner 110 inner chambers, and the nozzle 112 by the burner surface is ejected into the outside, and the air that is blown by the air blast 123 of air supplying part mixes the generation air mixture by air jet hole 122 ejections mutually with fuel simultaneously.
Air mixture under this state by ignition combustion, produce flame during continuous burning, the shell 210 that is provided with above by burner of burned flame strengthens firepower after flame being focused on the position of central flame export 211 like this, and this moment, firepower was sent to direct 400 ends of heating frying pans, heating chamber 322 backs.
The flame that is discharged from during 400 ends at heating chamber 322 flame heat frying pans does not directly pass through pot bracing ring 330 and flame drain tank 331, but suppress to produce eddy current mutually with the inhibition exhaust bracket 321 of interior boiler clothing 320 upper ends setting, prolongation is in 322 li time of staying of heating chamber, the means of utilizing the interior boiler clothing 320 of heating to produce radiations heat energies increase the firepower of heating chamber 322, with the further raising and the increase thermal efficiency.
Be that the flame that heating chamber 322 is discharged from increases interior boiler clothing 320 radiations heat energies to increase firepower by above-mentioned said technological means, reached than in the past for this reason and reduce fuel consumption, improve the purpose of firepower.
Since firepower concentrate the shell 210 of portion 200 be mounted on the boiler clothing backing ring 220, shell 210 can arbitrarily separate, therefore to the cleaning of burner 110 and air supplying part 120 and guarantee to keep in good repair more convenient.
Though in specification of the present invention, exemplified invention formerly, in technical field of the present invention, taked to change various technology.
