The purpose of this study is to develop a combustion burner for high-viscous liquid fuel such as waste oil, which is able to atomize high-viscous liquid using a little energy and is able to reduce pollutant emissions. The internal mixing twin-fluid atomizer developed in this study mixed waste oil and atomizing air with swirling flow in a mixing chamber. The effects of kinematic viscosity of liquid, geometric shapes and dimensions of the twin-fluid atomizer on spray characteristics were studied. The results indicated that atomization of high-viscous liquid was achieved with a little energy of atomizing air, and the spray with small droplets was obtained. Moreover, the atomizer, which the hole number of atomizer is single hole of N=1, the liquid supplying hole was multi holes of n=6 and the height of the mixing chamber is low of h=2mm, is suitable for atomization of high-viscous liquid and a large amount of liquid.
