Determination of energy plants chopping quality while biofuel preparation

Abstract

In the paper there are presented the energy crop chopping and preparation for biofuel equipment. As well you will find applied evaluation methods of determination chopping quality. Approved methodology for energy needs immature (one-two years of growth) willow chopping technique for determining the quality of chaff. There are presented results of the experimental research. For chopping immature willows were chopped by drum chopper of forage combine. There were observed of immature willow stem chaff chopping quality after the experimental study, in justice of use the drum chopping equipment prepared chaff fractional composition. The quality of stem chaff and chaff fineness was defined by two methods - according to the most widely used methodology approved by the EU and methodology approved in the Denmark. There were determinated willows stems chaff moisture content, density and calculated immature (one-two years of growth) willow stem chaff theoretical length while changing work duty of the drum chopper.
