Abstract :As the sources of fossil fuels are restricted and usage of them is resulted to GHG emission, it is necessary to use renewable energy sources as strong alternative for fossil fuel. Solid biomass is one of these renewable energy sources in order to produce heat and electric. In order to use solid biomass energy much more effectively it must be pelletized. Pelletizing is a mass and energy densification for materials with low bulk density such as sawdust, straw and other herbaceous energy crops. Pelletizing is a method of increasing the bulk density of biomass by mechanical pressure. The process assists to reduce transportation costs, provides better handling and feeding of the biomass and efficient storage with less dust formation. In the industrial scale, pelletizing of biomass is done by means of cylindrical pelletizing machines. Generally, these machines are manufactured by small scale companies. Samll scale pelletizing machine manufactures usully have not suffiicant knowlage and staff to run comprehensive mechanical strength analyses during machine design process. The objective of this study is to proper a simple program for mechanical strength analysis for main parts of cylindrical pelletizing machines.
