Biomass Pellet

In the present study, pyrolysis characteristics of corn straw pellet were studied in biomass pyrolysis test bench. The influence of pellet diameter on pyrolysis products was investigated. The results showed that: with the increase of pellet diameter, the yield of tar decreased ,and the yield of char and gas increased, and char density increased too. The results has significant theoretical guidance on the biomass gasification and preparation of char using biomass pellets.

Biomass Pellet

In the present study, catalytic pyrolysis characteristics of corn straw pellet were studied in biomass pyrolysis test bench. The effect of content of CaO added in biomass pellet on pyrolysis products was investigated. The results showed that: with the increase of CaO content, the yield of tar decreased ,and the yield of char and gas increased. Among gas compositions, the volume percentage of CO、H2、CH4 increased, while the volume percentage of CO2 decrease greatly. The Calorific values of the gas increase distinctly. The results have significant theoretical guidance on the application of biomass pellets in biomass gasification equipments.

This paper studies problematic of a mechanical system composed of different coupled parts submitted to a high speed shock and proposes analysis of anti vibratory passive and active methods based on an experimental and theoretical coupled approach. After a shock, different parts of the system oscillate. If one of them is excited at a particular frequency, such as its proper frequency, important oscillations appear and can lead to the deterioration of the system by introducing important stresses. In this paper, we propose an analysis in order to understand this kind of problem and what we can do to avoid it. Firstly, we discuss problematic and we expose the studied system. In a second time, we develop two approaches of modeling that allow us to understand the phenomenon by carrying out numerical simulations. Then cross checking of model is completed via experimental study on drop test bench. Passive minimization method of vibrations based on experimental and theoretical coupled approach is exposed. Finally, a comparative analysis of different methods of control and experimental results of controlled system are presented.

Aus Schwerzerspanung und Turbinenschaufelfertigung ist bekannt, dass Werkzeuge aus dem Spannfutter ausgezogen werden. Die veränderte Werkzeugposition führt zur Abweichung von den vorgegebenen Toleranzen und einer geringeren Fertigungsqualität oder Beschädigung des Werkstücks. Der Artikel untersucht das Auszugsverhalten verschiedener Spannfutter. Mit einem Prüfstand können die Einflüsse der mechanischen Belastung und der Klemmlänge auf die Haltekraft im Pressverband betrachtet und die Wirkmechanismen beim Auszug des Werkzeuges aus dem Spannfutter sensorisch ermittelt werden.   From heavy-duty cutting and turbine blade manufacturing it is known that tools pull out from chucks. A change in tool position leads to deviations from tolerance and decreases manufacturing quality or damages the workpiece. This article explores the extension behavior of different chucks on a specifically designed test bench. This allows determining how mechanical load and clamping length influence the holding force in the press fit and what mechanisms of action affect the extraction of the tool from the chuck.
