Electrostatic atomization combustion method and apparatus for liquid fuel

Abstract

The invention discloses an electrostatic atomization combustion method and apparatus for a liquid fuel. A pressure chamber is arranged just above a combustion chamber; a charging plate electrode is arranged in the pressure chamber and connected with a high-voltage electrostatic generator; the upper ends of a plurality of arrayed atomizing nozzles are all connected with the bottom of the pressure chamber and communicated with the interior of the pressure chamber; the lower segment of each atomizing nozzle vertically extends into the upper part in the combustion chamber from the top wall of the combustion chamber; a needle electrode is coaxially arranged in each atomizing nozzle, and the upper ends of all the needle electrodes are connected with the charging plate electrode; a liquid fuel tank is connected with the pressure chamber through a conveying pipeline; and an air or oxygen pressure tank is connected with the atomizing nozzles through connecting pipelines. The needle electrodes are used for electrostatic atomization of the liquid fuel and an air or oxygen gas medium is used for further impact auxiliary atomization of the liquid fuel at the outlets of the nozzles, so the liquid fuel is crushed into a charge-carrying droplet group with a smaller particle size; thus, the contact area between the fuel and air or oxygen is increased, and combustion efficiency is improved.

technical field [0001] The invention relates to an electrostatic atomization technology of liquid fuel, which realizes the full combustion of different liquid fuels. Background technique [0002] Electrostatic atomization is a liquid atomization method that relies on electrostatic force. The droplets produced by atomization have many advantages such as small particle size, monodisperse uniform distribution, stable state, and narrow droplet size distribution range. Various fields such as particle preparation, atomized combustion, inkjet printing, and bioengineering have broad application prospects. Using electrostatic atomization technology for liquid fuel can break the liquid fuel into fine droplets and increase the total surface area of ​​the fuel droplets, that is, the contact area with the air, which can make the liquid fuel burn more fully and improve the combustion efficiency. [0003] At present, there are two different ways to use atomization technology to improve th...

Problems solved by technology

However, the problem with this liquid fuel gasification burner is that the liquid cannot be gasified at the beginning of combustion, and during the combustion process, due to the high heat required for the gasification of gasoline and diesel, the gasification effect often cannot obtain the expected effect

However, due to the complexity of the nozzle structure, the manufacturing is more complicated and the cost is higher; and the insulating ceramic tube inside the nozzle is not conducive to the formation of ion clusters

[0005] Therefore, the electrostatic atomization technology of the above-mentioned various liquid fuels has technical limitations in aspects such as liquid atomization combustion and liquid fuel gasification combustion, etc., and there is an urgent need for an effective liquid fuel atomization or gasification combustion method in this field. Provides combustion efficiency for liquid fuels
