The Comparison Study on the Performance of Centrifugal Atomizer

High speed rotating centrifugal atomizer is the key equipment for the flue gas processing. The centrifugal high-speed atomizer is running at high speed, it makes micron liquid-drop in order that chemical reaction happened between micron drop and harmful gas. Its function has direct impact to the emission produced from WTE(waste to energy) plant. The different driving form affects the atomizers stability of high speed movement, atomization effect and the running life directly. For a long time, the transmission quality of belt drive or direct coupling drive is one of the focus issues. Based on the high speed centrifugal atomizer, this paper introduces the two commonly used driving forms of the atomizer, and compares their performance through the experiments. Key words: atomizer, WTE, experiment

Analysis of Dynamic Characteristics of Key Parts of Centrifugal Atomizer in Waste to Energy

Uneven distribution of mass and temperature usually have important effects on the dynamic characteristics of rotary mechanism. Based on thermal-structural coupling theory, dynamic response analyses of the flexible rotor of centrifugal atomizer can be done by FEM. Considering eccentric quantity is caused by nozzle clogging and axial non-uniform distribution of temperature, the dynamic characteristics of the is studied; the response of mass unbalance and thermal bending or coupled the both is researched and compared. It is shown from the calculation that all of the three conditions have affected the dynamic characteristics of rotor system and the design can basically meet the stable operation requirement of the atomizer. The results can be applied to improve the design of the centrifugal atomizer. Developing more detail analysis to optimize the design in the future research.

Centrifugal Atomization of Metals: Thermodynamics of the Process

A complete description of the parts of a centrifugal atomizer, with geometries and dimensions are shown. Tests of atomization were carried out by using pure tin metal in air atmosphere. Mathematical simulation of the thermodynamics of the process was successful to describe the centrifugal atomization, showing a maximum experimental correspondence mismatch of 14%.
