Abstract: As a kind of special liquid-solid mixture consisting of nanoparticles and base fuel,liquid nanofuel has many advantages such as high heat transport capability,good catalytic combustion performance and low pollutant emission. However,the small size characteristic of nanoparticle makes the heat and mass transport mechanism,spray and evaporation performance,and combustion chemical reaction of liquid nanofuel very complex,leading to imperfection of the theories and application of liquid nanofuel for combustion enhancement. In this paper,the approaches of preparation and stability treatment for liquid nanofuel are introduced firstly. Then,the effects of nanoparticles on thermophysical parameters,atomization,evaporation and combustion characteristics of base fuel are analyzed in detail. In addition,the potential application values of liquid nanofuel in power plants for improving performance and reducing emission are reviewed emphatically. On this basis,this paper envisions the future research trends of liquid nanofuel for combustion enhancement. It is indicated that the efficient and controllable preparation approach,characteristics and mathematical description of thermophysical parameters,mechanisms of catalytic combustion and emission reduction are the important problems to be solved in the field of liquid nanofuel.

Key words: liquid nanofuel, nanoparticle, thermophysical property, combustion enhancement, emission control
