Alcohol-based liquid fuel dual-phase self-atomization industrial combustor

Abstract

An alcohol-based liquid fuel dual-phase self-atomization industrial combustor comprises a combustor body, an alcohol-based liquid fuel delivery device and an alcohol-based liquid fuel gasification and delivery device which are matched mutually. The combustor body comprises a combustor housing, the combustor housing is provided with a fan interface, and an atomization combustion assembly is arranged in the combustor housing. The alcohol-based liquid fuel gasification and delivery device comprises a phase change device, wherein an electric heating element and a gasification tube are arranged in the phase change device, one end of the gasification tube extends out of the phase change device to form a gasification tube inlet for input of alcohol-based liquid fuel, the other end of the gasification tube extends out of the phase change device to form a gasification and delivery tube for outputting the gasified alcohol-based liquid fuel to the atomization combustion assembly in the combustor body, and the alcohol-based liquid fuel gas is utilized to conduct atomization, ignition and combustion on another way of alcohol-based liquid fuel. The alcohol-based liquid fuel dual-phase self-atomization industrial combustor creates conditions for ensuring complete combustion of the alcohol-based liquid fuel and can meet the industrial high-power combustion demand.

[0002] Alcohol-based fuels are fuels mainly composed of alcohols (such as methanol), which exist in liquid form under normal temperature and pressure. The most potential new alternative energy source is favored by business organizations in various countries; among the existing liquid fuel atomization combustion technologies, there is no technology that adapts to the characteristics of alcohol-based fuels. It is necessary to make the combustion effect of alcohol-based liquid fuels meet the application requirements in the industrial field , so that the fuel is fully atomized and the atomized particles are reduced, the easier it is to fully mix with the combustion-supporting air, so that the liquid fuel can be completely burned. The current pressure atomization technology, mechanical atomization technology, and medium atomization technology are used for alcohol-based The fuel effect is not ideal, and complete combustion cannot be achieved. Especially in industrial high-power applications, alcohol-based liquid fuel atomization combustion has insufficient combustion, low combustion intensity, and low flame temperature, which basically cannot meet industrial combustion requirements, and the equipment is complicated. Many faults

Although the gasification combustion effect of alcohol-based fuel is good, in high-power applications, the large-flow gasification alcohol-based fuel equipment is complicated and costly, so the complete gasification burner is generally only suitable for burners below 300kW
