Abstract

The utility model belongs to a range using fuel oil or liquid gas as fuel, especially a gasifying-burning range capable of preheating the fuel, which is aimed to realize a range capable of automatically carrying out thorough liquid fuel preheating and vaporisation before getting into the working state of combustion and is mainly composed of a range casing, a range core, a heating jacket, a coiled pipe, an insulation lining, a fuel nozzle, etc., wherein, the heating jacket is arranged on the upper part of a core casing of the range core, the coiled pipe is coiled on the outer wall of the heating jacket, and the insulation lining is arranged between the coiled pipe and an opening on the upper part of the range casing. The disclosed structure enables the fuel to be heated thoroughly in the coiled pipe, the fuel burns completely, and the range has high heat efficiency.

Description

Can preheat the vaporization combustion kitchen range of fuel

The utility model belongs to the kitchen range of making fuel of fuel oil or liquefaction vapour.

Be the kitchen range of fuel with fuel oil (as diesel oil, kerosene) etc., to preheat effect bad because of the structure limitation can not preheat fuel or fuel in the past, and fogging degree was low when fuel entered burning, and it is insufficient burn, and combustion heat value is low, and the fuel use is uneconomical.

The utility model purpose is to realize that a kind of fuel of convection cell voluntarily fully preheats, and makes its atomizing enter the kitchen range of work fired state again.

The utility model is mainly by the kitchen range shell, the kitchen range core, heated jacket, coil pipe, the insulation lining, fuel nozzle, electronic ignition device and air inlet, the kitchen range shell is uncovered shape bucket, opening and blast pipe UNICOM are arranged at the bottom, the kitchen range core is positioned at the top of said uncovered shape bucket, by the core shell, core print seat, mixing chamber and combustion head constitute, the core shell is last, the tube of under shed, be furnished with fresh air inlet on the wall, core print seat is that dish type is enclosed in core shell bottom, fuel nozzle is positioned at the core print seat middle part of core shell, heated jacket is positioned at the top of core shell, coil pipe coils in the heated jacket outer wall, be the insulation lining between the uncovered inwall of coil pipe and said uncovered shape bucket, coil pipe one end is through fuel nozzle UNICOM fuel nozzle, and the other end is through advancing fuel conductor UNICOM fuel valve.

Combustion head described in the utility model is made up of tray for combustion, flame-guiding hood and flame-cover, and tray for combustion is arranged in upper shed place of said kitchen range core, and flame-guiding hood covers on the tray for combustion middle part, and the hungry ghosts who spit fire is led at the top, and flame-cover covers tray for combustion outside flame-guiding hood, be furnished with flame-hole on it.

Mixing chamber described in the utility model is made up of cylindrical tube and following cover, and following cover is buckled on the core print seat dish, and cloth is porose on the cylindrical tube tube wall, and its lower end is communicated with cover down, at the bottom of the upper end connection tray for combustion.

When using the utility model, open fuel valve earlier, allow flow through coil pipe and spray into the cylindrical tube of mixing chamber of a little fuel (as coal, diesel oil etc.) from fuel nozzle, light fuel in the cylindrical tube with electronic ignition device, strengthen the fuel straying quatity, be allowed to condition on the combustion head and burn, kitchen range advance as pre-duty.The heat that burnt fuel produced on combustion head, be radiated the heated jacket on core shell top through tray for combustion, its heating plate is around in the coil pipe of its outer wall, because of coil pipe is constantly heated by heated jacket, coil pipe has the insulation lining outward again, the temperature loss of coil pipe is few, and temperature is more and more higher in the coil pipe, and the fuel of flowing through wherein is also more and more abundant in the preheating before the fuel nozzle ejection; Preheating is fine, from the fuel of fuel nozzle ejection through mixing chamber heat again repeatedly and atomizing enters the combustion head burning, fuel at this moment is " hot mist attitude ", makes the kitchen range burning that enters normal operating conditions very abundant.

The disclosed structure of the utility model can permit voluntarily divides the fuel of pre-heated flow in coil pipe, and makes it be heated, atomize by powerful repeatedly in mixing chamber, the little aqueous composition of its combustion flame when combustion head burns, and the thermal efficiency of kitchen range is high.The utility model is easy to realize, also is applicable to various combustion gas class A fuel As.

The utility model is described in further detail below in conjunction with accompanying drawing.

Accompanying drawing is the utility model structure cutaway view.

Among the figure, the 1-blast pipe, 2-kitchen range shell, the 3-core print seat, 4-is cover down, 5-electronic ignition device (electric plug), 6-core shell, 7-is incubated lining, 8-coil pipe, 9-flame-cover, 10-flame-guiding hood, 11-tray for combustion, the 12-heated jacket, the 13-cylindrical tube, 14-advances fuel conductor, 15-fuel nozzle, 16-fuel nozzle.

Embodiment: present embodiment is made of accompanying drawing.

As shown in the figure, the kitchen range shell (2) that can preheat the vaporization combustion kitchen range of fuel is uncovered drum, the opening of its bottom and blast pipe (1) UNICOM that uses air blast.Core shell (6) is one to be furnished with the upper and lower opening cylinder of fresh air inlet on it, and disc core print seat (3) is enclosed in core shell (6) bottom, and fuel nozzle (16) is fixed in core print seat (3) middle part up; Circular boop shape heated jacket (12) is on core shell (6) top, coil pipe (8) coils in a spiral manner in heated jacket (12) outer wall, the one end is through passing fuel nozzle (15) UNICOM's fuel nozzle (16) of insulation lining (7), kitchen range shell (2) and core print seat (3), and the other end advances fuel conductor (14) UNICOM fuel valve through what pass insulation lining (7) and kitchen range shell (2).Insulation lining (7) is filled between the inwall of coil pipe (8) and said kitchen range shell (2) open topped, and the heated jacket (12) and the top of kitchen range shell (2) are fixed.
