Alcohol-base fuel ejecting self-adaptive air distributing burner

Abstract

The invention discloses an alcohol-base fuel ejecting self-adaptive air distributing burner which comprises a burner body and an ejecting device. The burner body is internally provided with a burning chamber; the burning chamber is provided with a spiral vaporizer; the spiral vaporizer is provided with a gas burning agent outlet and a liquid burning agent inlet; the ejecting device is provided a burning-agent spraying nozzle, an sucking section, a mixing section, a diffusing section and a contracting section; the burning-agent spraying nozzle and the ejecting device are coaxially arranged on the joint of the burning chamber in sequence; the burning-agent spraying nozzle is arranged on the inlet of the sucking section of the ejecting device through a burning-agent spraying nozzle support; the gas burning agent outlet leads to the inlet end of the burning-agent spraying nozzle; the length ratio of the mixing section, the diffusing section, the contracting section and the burning chamber is 5:5:1:10; and the diameter ratio of the sucking section, the throat of the ejecting device, the outlet of the diffusing section, the outlet of the contracting section and the burning chamber is 2:1:1.8:1.4:5.2. Due to the optimization of the ratio of the ejecting device and the structure of each section of the burning chamber, the self-adaptive air distribution is realized, and stable and reliable burning is achieved.

Description

technical field [0001] The invention relates to an injection burner burning alcohol-based fuel, in particular to an alcohol-based fuel injection self-adaptive air distribution burner. [0002] Background technique [0003] With the overall development of our country's economy, the demand for energy is increasing. Today, when fossil energy is in short supply and the environment is seriously polluted, people are constantly looking for a new energy to replace the existing fossil fuel. Alcohol-based fuel has become the object of continuous research because of its chemical properties similar to gasoline and diesel. The widespread use of alcohol-based fuels is mainly to replace industrial fuels and meet the needs of rural household fuels. The widespread use of alcohol-based fuels can alleviate the threat of the energy crisis to my country's national economic development and people's lives, but the most important problem facing us now is the need for a safe, efficient, and easy-t...

Problems solved by technology

Therefore, the combustion temperature during combustion is low, the structure of the burner is very complicated, the operability and safety are greatly affected, and the combustion efficiency is very low.

[0005] The current ejector burner, because it is partly premixed or completely premixed, has high combustion efficiency and is widely used in natural gas and liquefied petroleum gas. However, it is mainly used for ejector burners burning alcohol-based fuels. burner but no

Another problem existing in the existing injector burner is that the automatic adjustment ability is poor. When the power changes greatly, the amount of injected air will seriously deviate from the designed injection amount, which will reduce the combustion efficiency.

The current ejector burners generally use manual or external adjustment devices to change the throat area of ​​the ejector or the size of the air intake port to adjust the amount of ejected air. This operation requires certain skills and cannot guarantee the combustion. optimal air volume
