Description

Multi-stage split energy-saving combustion device for liquid fuel

Technical Field

The invention relates to the field of liquid fuel stoves, in particular to a multistage split energy-saving combustion device for liquid fuel.

Background

In the vast market of commercial kitchen ranges, liquefied gas fuel such as a gas tank is widely used for occasions of multiple cooking ranges such as schools, restaurants and hotels, and the traditional liquefied gas has the problems of low heat value, high cost, low flash point, flammability, explosiveness, high potential safety hazard and the like. So that the fuel of the commercial kitchen range starts to turn to a safe fuel with higher flash point, namely a liquid fuel (coal liquid fuel). The liquid fuel for coal-base kitchen range is a clean fuel for liquid kitchen range, which is made up by using Fischer-Tropsch synthetic hydrocarbon, industrial white oil, high-flash hydrocarbon compound and the like as raw materials, and compounding high-molecular oxygen-containing compound and additive. The fuel oil has the main advantages of wide application, low price, high heat value, good safety, cleanness and environmental protection.

The current liquid fuel kitchen ranges are mainly electric spraying fuel oil ranges in the fuel supply mode, the application field is mainly a series of Chinese food frying ranges and big cooking ranges of commercial strong fire kitchen ranges, the liquid fuel oil range is also used for some other kitchen ranges such as a steam box, a marinating barrel, a steaming stove, a boiling stove and the like and warmer products, and the fuel oil is vaporized by adopting a pulse oil pump.

The combustion mode of the electric spraying fuel oil stove needs to pressurize liquid fuel to 12 kg pressure firstly to ensure that the liquid fuel sprayed out of an atomization nozzle is atomized, the atomized liquid fuel can be mixed with air pumped by a fan in a stove air cavity to burn, then 2 ten thousand volts of voltage is generated through an ignition needle to ignite mixed gas, primary combustion is realized in the air cavity of the stove, the mixed gas is released into a stove basin after passing through a fire gathering ring, and secondary full combustion is performed, so that the heating of a pot is realized, and the electric spraying fuel oil stove is shown in fig. 7. The electric spraying stove belongs to a developed combustion system, liquid fuel is required to be sprayed after being pressurized to realize atomization, a fan is used for blowing combustion supporting, and the volume of the liquid fuel is expanded in the vaporization and combustion processes, so that the pressure in a stove basin is also relatively high, and when a large number of commercial stoves are used for fierce fire, flame is sprayed out from the side face of a pot, and at the moment, a large number of fuels are sprayed out from exhaust ports on two sides of the stove basin without heating the bottom of the pot, so that the heat utilization rate of the electric spraying fuel stove on the market at present is very low, and is mostly about 22%.

Because the fuel injected by pressurization cannot directly contact the bottom of the cooker, a certain distance is required to be kept between the fuel and the cooker, so that enough space vaporization of the liquid fuel can be ensured, flame cannot be concentrated at the bottom of the cooker for full heating during secondary combustion, and the flame is difficult to be completely concentrated at the bottom of the cooker even though a fire gathering ring is added on a cooker for gathering fire, and the reason of low heat utilization of open combustion such as an electric spray cooker is also caused.

The electronic injection method is just to atomize the liquid fuel to meet the combustion condition, and vaporization of the liquid fuel is not truly realized, so that rapid combustion is not easy to complete. And the liquid fuel needs to be pressurized to ensure that atomization is realized, so that the electric energy needs to be large, a 220V power supply is needed to supply power, an external electric wire is needed, the use environment of the liquid cooker is limited, and the liquid cooker cannot be independently used outdoors. The existing electronic fuel injection fuel stove cannot be adjusted to small fire, oil inlet amount is reduced when the small fire is started, oil inlet pressure of a spray head is reduced due to the fact that the oil inlet amount is reduced, atomization conditions of the spray head cannot be met, therefore, the minimum flow requirement for the oil injection amount is met under a certain pressure, for example, an atomization nozzle with the caliber of 0.65 is achieved, and the minimum flow requirement is 700g/h. Therefore, the existing electric spraying fuel oil kitchen range is only suitable for dining kitchens and canteens and the like, and places with strong fire stir-frying can not be applied to environments requiring small fire, such as hotels, clay pot restaurants and the like. In addition, many existing gas stoves have flameout protection function, and the electronic injection stoves have very high working temperature and have no flameout protection function because of limited environment.
