Foreword
The production of pellets, as a renewable energy source, is continuously increasing worldwide. Industrial and agricultural wastes, by-products, and residues are available in all countries of the world, and one of the rational uses of these materials is the pellet making supply energy. Furthermore, a major advantage, using these by-products for energy production, contributes to the reduction of CO2 emission to the environment. This book is the first attempt to provide a comprehensive theoretical approach for the compaction process of various bulk materials prepared from wood wastes and by-products. A nonlinear rheological compaction model is developed and demonstrated with experimental results. A new similarity relationship is developed for the quick estimate of compaction energy as a function of the influencing variables. Furthermore, for the proper selection of channel length of the die ring a new approach is developed based on experimental measurements. The practice of pellet making is equally treated in detail. There are many practical problems which fundamentally influence the production process. The preparation of the raw material, a continuous and accurate material flow to the press, the post-processing of pellets, and the economic analysis of the pellet production
