Operating conditions and fuel properties are important to the atomization quality, which is an inevitable problem that the liquid fuel has to face, specifically for new alternative fuels. One of the recognized atomization methods is the liquid sheet formed by the oblique fuel jet or spray impinging onto a plate in a direct injection (DI) engine. In this paper, a series of experiments that deal with...
Complex interactions among components in the heterogeneous grinding have an influence on breakage and energy consumption characteristics of components in mixtures if compared with the single breakage. In this paper, a modified Hardgrove mill, with the addition of a power meter, is used to simulate the grinding process of vertical spindle pulverizer. Binary-component mixtures of coal and pyrite, or...
As the demand for the high-quality transportation fuels grow rapidly, deep hydrogenation of diesel for aromatics reduction plays an important role in petroleum refinery. In this paper, a sulfur-tolerant noble metal hydrogenation catalyst, Pt/mesoporous KA zeolite (Pt/MKAZ), was developed based on the shape selective and hydrogen spillover concepts. Different kinds of catalysts were prepared by carefully...
As an important pulverizing equipment, the vertical spindle pulverizer (VSP) is widely used in power plants to produce fines for combustion. But high temperature and pressure in VSP limit the study of grinding process. Herein, a laboratory roller mill, with the addition of a power recorder, has been designed for the simulated study. Parameters of loading force, table revolution rate and fractional...
A two-phase turbulent combustion model (FSM) with the inclusion of individual droplet burning behavior was applied in a methanol air spray flame. The FSM model results were compared with the experimental data and results of the traditional two-phase turbulent combustion model (TM). The comparison of the results showed that in most regions the FSM model results were in good agreement with the experimental...
