Description

Liquid, solid fuel multifuel combustion device

The utility model relates to combustion apparatus, particularly a kind of liquid fuel and solid fuel multifuel combustion device.This device uses especially that burning-point height, viscosity are big, combustibility is poor, liquid, air-flow fluid fuel and the solid fuel multifuel combustion better effects if of water mixing, aeration.

At Industrial Boiler, catering industry and home-use liquid fuel and solid fuel, all be the single fire heat supply at present, burn method like this, the advantage of each form fuel can not get rationally, makes full use of, and combustion efficiency is not really desirable.As: the single fire liquid fuel, consumption is big, the valency height, user effort is big; The single fire solid fuel, most of heat energy only concentrates on furnace chamber, and calorific value can not make full use of and waste, and firepower is difficult to regulation and control again.

The purpose of this utility model just provides a kind of liquid, solid fuel multifuel combustion device, overcome the deficiency of liquid, solid fuel single fire, and liquid, solid imitation frosted glass multifuel combustion are given full play to the advantage of each form fuel, improve its economic worth greatly.

Below in conjunction with drawings and Examples realization the utility model is elaborated:

Fig. 1 is a schematic diagram of the present utility model, among the figure: 1. air pump; 2. fluid fuel hold-up tank; 3. fluid fuel switch; 4. fluid fuel cleaner; 5. Compressed Gas switch; 6. Compressed Gas cleaner; 7. liquid, gas blender; 8. shower nozzle; 9. stove and accessory; 10. liquid, gas hybrid switch; 11. three-way pipe; 12. fluid fuel pressure-reducing valve; 13. Compressed Gas pressure-reducing valve; 14. fluid fuel jar safety valve; 15. air gauge; 16. baroswitch; 17. fluid fuel sprays into the hole.

Its structure is as shown in Figure 1: this device is mainly by air pump 1, fluid fuel tank 2, fluid fuel switch 3, stream Fluid fuel cleaner 4, Compressed Gas switch 5, Compressed Gas cleaner 6, liquid air mixer 7, shower nozzle 8 and stove Tool 9 connects to form by pipe. Under the fire door of stove and accessory 9, the combustion chamber upper portion side wall has fluid fuel and sprays into the hole 17 communicate with furnace body outer wall, and the oral area that sprays into hole 17 at the furnace body outer wall fluid fuel is equipped with shower nozzle 8; Can also In the bottom of stove and accessory 9 combustion chambers, be equipped with that vertically to wear to the metal heat transfer pipe to fire door be that fluid fuel sprays into the hole 17, the fluid fuel in metal heat transfer pipe lower end sprays into hole 17 oral areas dress shower nozzle 8, on fluid fuel tank 2 Fluid fuel tank safety valve 14, air gauge 15, baroswitch 16 are housed, fluid fuel tank 2 and liquid, gas On the tube connector between the blender 7, establish respectively fluid fuel switch 3, fluid fuel cleaner 4, fluid fuel Pressure-reducing valve 12 and Compressed Gas switch 5, Compressed Gas cleaner 6, Compressed Gas pressure-reducing valve 13, liquid, gas mix Three-way pipe 11, mixed liquor, air cock 10 are housed on the tube connector between device 7 and the stove and accessory 9 connect shower nozzle 8.

Embodiment is referring to Fig. 1: place the combustion chamber of stove and accessory 9 to ignite in solid fuel.Power supply is behind the baroswitch on the fluid fuel jar 16, start the Compressed Gas of air pump 1 generation again and send into fluid fuel jar 2, when the total indicator reading of air gauge 15 on the fluid fuel jar reaches the requirement force value, baroswitch 16 can utilize the power supply of Compressed Gas automatic disconnection air pump, when pressure surpasses setting, by fluid fuel jar safety valve 14 gas is discharged, to ensure safety, at this moment, drive Compressed Gas switch 5 earlier, after drive fluid fuel switch 3, Compressed Gas in the fluid fuel jar and liquid fuel be compressed gas switch 5 respectively, Compressed Gas cleaner 6, Compressed Gas pressure-reducing valve 13 and fluid fuel switch 3, fluid fuel cleaner 4, fluid fuel pressure-reducing valve 12, enter liquid, gas blender 7 proportionings become premix gas, spray mixed liquor by three-way pipe 11 from shower nozzle 8 spent solid fuel to stove and accessory 9 combustion chambers, the solid fuel high temperature that gas is met burning is pyrolysis gasification and solid fuel multifuel combustion.This device can connect a plurality of stove and accessorys 9 by many siphunculus and carry out multifuel combustion; Fluid fuel switch 3 and Compressed Gas switch 5 be Push And Release controlled fluid fuel and compressed gas flow size respectively; Fluid fuel pressure-reducing valve 12 and Compressed Gas pressure-reducing valve 13 keep sending fluid fuel and Compressed Gas at a steady state value.If suspend some stove and accessory multifuel combustions with fiery, the mixed liquor, the air cock 10 that only close this stove and accessory get final product; All stop multifuel combustion with fire as whole stove and accessorys, just close liquid fuel switch 3 earlier, Compressed Gas switch 5 is closed in the back, and the pressure in the fluid fuel jar 2 is regulated automatically by fluid fuel jar safety valve 14 and baroswitch 16.When with the low ignition point liquid fuel when having fired the solid fuel multifuel combustion, must close Compressed Gas switch 5, with anti-backfire; When needing little fire, can close liquid fuel switch 3, regulate Compressed Gas switch 5 and send that a small amount of gas is combustion-supporting to get final product.

Advantage of the present utility model:

The solid fuel ignition time long, the fluid fuel multifuel combustion is exempted to light a fire and is met the characteristic of Pintsch process gasification, and combustion Obtain rationally, take full advantage of, burning fully, the thermal efficiency is good.

2. it is combustion-supporting with the gas multifuel combustion that liquid fuel can mix the water of volume, and burnup is few, and energy savings reduces environmental pollution, good economy performance.
