branches of Tetraploid Black Locust are the ideal resource to produce biomass briquette. But its special features lead to the low values and high energy consumption. In this paper, experimental researches were done on self-made chipping machine, and cutting force was determined that the maximum was 454.4N and the average was 264.34N. Higher qualified rate of chip can be reached while cutting gap was...
The design is bio-fuel raw material drying equipment which is cross-flow belt dryer based on high-temperature hot water as the medium. According to the drying experiments, obtained the drying curve of materials at different temperatures. Through the experimental data, the general parameters of dryer were determined. The features of this design is that heat from the high-temperature hot which comes...
Plenty of desert brush grows in the north of China. Brush does not only have great influence on ecology, which serves for conserving soil and water and checking winds and fix drifting sand, but also have great benefits on economy, which serves as energy forest, raw material forest and forage forest. In order to solve the problem of cutting brush in sandy area in north of China, a self-propelled walking...
There are factors which involve with pressure and moisture content in the orthogonal design for the bio-fuel high dense shaping at room temperature. Make use of SPSS to carry out ANOVA analysis and Range analysis which can indicate how the shaping density is influenced by the different pressure and moisture content and judge the importance of the two factors for shaping density of bio-fuel. This research...
Bush is one of raw material for biomass fuel in China. Crank speed is an important parameter in the design of bush reciprocating cutter. A reciprocating single blade cutting test equipment was made in this paper. One factor test was done to study its influence on maximum cutting force of bush. Other tests were done to study the interaction of cutting edge angle and crank speed, as well as sliding...
