Description

A special liquid fuel cooker

technical field

The utility model relates to a liquid fuel stove, which belongs to the technical field of stove manufacture.

Background technique

The fuels generally used in the cooking stoves of major hotels, hotels and canteens of enterprises and institutions have oil (diesel oil, kerosene), gas (liquefied petroleum gas, coal gas, natural gas) at present. In actual use, the former has insufficient combustion, low thermal efficiency, high energy consumption, slow ignition and temperature rise, and serious pollution. The latter is dangerous, expensive and tends to rise higher and higher. Liquid alcohol-based fuel is known as the "green energy source" in the 21st century. Its economy, safety, environmental protection, wide range of raw material sources, and low price are all superior to the above-mentioned oil and gas. Therefore, today when energy is in short supply, prices are constantly rising, and cooking pollution is becoming more and more serious, liquid alcohol-based fuel will be the most valuable cooking alternative fuel in the future. But the kitchen range of existing structure is difficult to normally use due to factors such as preheating during actual operation, vaporization, closure, blockage, safety, environmental protection, maintenance and the like when using liquid fuel.

Contents of the invention

The purpose of the utility model is to provide a liquid fuel cooking range with reasonable design, which can effectively improve combustion efficiency and reduce environmental pollution.

The utility model relates to a liquid fuel special cooker, which comprises a combustion chamber cover with a combustion chamber base inside. Injection hole, igniter, split fire carburetor casing with fuel steam nozzle hole, lower screw with liquid fuel pipe and preheating fuel pipe inside; A liquid fuel outlet hole is opened on the liquid fuel pipe at the upper part, and a liquid fuel outlet hole is opened on the preheated fuel pipe at the lower part of the fire-distributing vaporizer. When in use, first ignite and burn the preheated fuel flowing out of the preheated fuel liquid outlet hole to preheat the split fire vaporizer, and then heat the liquid fuel flowing out of the liquid fuel liquid outlet hole along the spiral vaporization chamber in the split fire vaporizer Vaporized, mixed with the burning preheated flame through the fuel steam nozzle, and supplied with oxygen by the air nozzle for combustion.

Flame-distributing wings can also be provided on the outer periphery of the jacket of the flame-distributing carburetor to guide the air so that the air and fuel vapor can be fully combined to further improve the combustion efficiency of the fuel.

A preheating fuel guide groove can also be provided around the air injection hole on the base of the combustion chamber to facilitate the accumulation of the preheating fuel.

The bottom of the air buffer outer cover and the lower screw rod can also be connected and fixed by the locking nut of the air cover.

The flame distribution carburetor cover and the top of the liquid fuel pipe can also be connected and fixed by the flame distribution carburetor locking nut, so that the flame distribution carburetor in the flame distribution carburetor jacket can be disassembled and cleaned.

The utility model realizes the organic unity of vaporization, atomization and weathering through the preheating combustion of the preheating fuel, and is a kind of full combustion, high efficiency, energy saving, Safe and environment-friendly liquid fuel special cooker. Compared with the prior art, it has the following outstanding advantages and positive effects:

1. Reasonable design, compact structure, simple operation, easy disassembly and assembly, and quick cleaning;

2. Pulse ignition, short warm-up time, strong firepower, high efficiency, stable performance, and realized control and controlled synchronization, the firepower can be adjusted arbitrarily;

3. Liquid combustion is synchronized through vaporization, atomization, and weathering to achieve complete combustion, smokeless, odorless, non-toxic, and exhaust emissions are far below national standards;

4. It is suitable for alcohol-based fuels such as methanol and ethanol and oil-based fuels such as diesel and kerosene, with low combustion cost and good economic benefits.
