High Load and Less CO2 Burner Combustion of Incombustible Fuels Applying an Injector on the Concept of Fuel-water Rapid Mixing

本研究尝试将不燃性燃料用于燃烧器燃烧。其关键技术是在燃烧区引入水。基于燃料-水内部快速混合的概念，研制了一种喷射器。喷射器在加压空气的支持下促进燃料与水的快速混合。燃烧器燃烧试验表明，油水快速混合对降低氮氧化物和颗粒物等废气排放是有效的。此外，高负荷低污染燃烧有可能通过减少排烟热损失来提高锅炉系统的热效率。

This study tried to use incombustibility fuel in burner combustion. The key technology is introducing water in combustion field. An injector based on the concept of fuel-water internally rapid mixing has been developed. The injector promotes rapid mixing of fuel with water with support of pressurized air. Experiment of the burner combustion reveals that fuel-water rapid mixing is effective on reduction of exhaust emissions, such as nitrogen oxides and particulate matters. Moreover, lower pollutant combustion at high load has a possibility to improve thermal efficiency in boiler system by means of reduction of thermal loss of exhaust gas.
