Vaporized fuel oil furnace

Abstract

The invention discloses a vaporized fuel oil furnace which comprises a furnace body and a furnace end, and the furnace body comprises a combustion cavity, a vaporization cavity and an electric heating device; the vaporization cavity comprises a primary cavity and a final-stage cavity, and the electric heating device is arranged around the final-stage cavity and is electrically connected with a power supply; the furnace end comprises a fire spraying sleeve and a fire spraying head; the fire spraying sleeve is provided with a placing cavity for placing the fire spraying head in a sleeving manner; the fire spraying head comprises a splitter plate, a guide cavity and an adjusting cylinder; the splitter plate is sealed at the top of the placing cavity; the splitter plate is provided with an air injection sub-runner and a flow guide hole; the outlet of the air injection sub-runner points to the combustion cavity, and inlets of the air injection sub-runner communicates with the placing cavity; the flow guide hole is formed in the bottom of the splitter plate, and two ends of the flow guide hole communicate with the guide cavity and the placing cavity respectively; and the lower bottom of the adjusting cylinder is open, the upper bottom of the adjusting cylinder is sealed and is provided with a vent hole, the upper end of the adjusting cylinder is arranged in the guide cavity and is in threaded connection with the inner wall of the guide cavity, and the lower end of the adjusting cylinder communicates with a communicating cavity, so that the flow of the alcohol-based steam transmitted from the guide cavity to the flow guide hole is adjusted.

Description

technical field [0001] The invention relates to a combustion stove, in particular to a gasification fuel burner. Background technique [0002] Alcohol-based fuel (methanol fuel) has the advantages of low fuel consumption, much higher firepower than liquefied petroleum gas, more economical use, safety, and environmental protection. It is widely used in hotels, restaurants, guesthouses, school canteens, fast food, restaurants, etc. Alcohol-based gasification combustion furnaces have also gradually developed. [0003] Currently used vaporized fuel burners, because the temperature in the furnace body vaporization chamber is generally below 120°C, resulting in incomplete vaporization of the fuel, resulting in incomplete combustion of the vaporized fuel in the furnace; when the purity of alcohol-based fuel is lower than 70% or in a cold environment In winter, especially when the temperature in the north is below -10°C, the preheating and vaporization of alcohol-based fuel takes a...

Problems solved by technology

[0003] Currently used vaporized fuel burners, because the temperature in the furnace body vaporization chamber is generally below 120°C, resulting in incomplete vaporization of the fuel, resulting in incomplete combustion of the vaporized fuel in the furnace; when the purity of alcohol-based fuel is lower than 70% or in a cold environment In winter, especially when the temperature in the north is below -10°C, the preheating and vaporization of alcohol-based fuel takes a long time, making it difficult to ignite and inconvenient to use

[0004] Secondly, due to the carbon deposition in the vaporization combustion process of the alcohol-based fuel, the carbon deposition accumulates in the vaporization chamber of the vaporization fuel burner body, which makes the gas channel of the vaporization chamber of the vaporization fuel burner body easily blocked, resulting in the failure of the alcohol-based vaporization burner Work, high maintenance cost, inconvenient to use

[0005] Thirdly, the currently used alcohol-based vaporization burner, the vaporized fuel burner nozzle sprays a large amount of vaporized fuel, while the fuel injection volume of the vaporized fuel burner used in hotels, restaurants, guesthouses, school cafeterias, etc. is different, Due to the special nature of alcohol-based vaporized fuel combustion, the same vaporized fuel burner cannot be used in hotels, restaurants, guesthouses, and school cafeterias by adjusting the fire valve of the vaporized furnace. It is necessary to produce vaporized fuels with different fuel injection quantities or models. Stove head, resulting in high production cost and inconvenient
