In the agriculture, forestry, the primary and secondary wood working industry there are considerable resources of raw materials which can only be used in a rational manner for energetic purposes. Due to requirements from the users. one of the most retinal way of utilization is to make pellets with high density and specific energy content. Making pellets of 6-8 mm diameter, their utilization in furnaces allows an almost fully automated operation with high thermal efficiency. This book describes both the theoretical and practical aspects of pellet production including material requirements and preparation, pressing technologies, quality requirements, burning properties, investments and the overall economy of pellet production.

This book examines a topic which is an indispensable part of any production line in the wood industry: the extraction, separation, handling of dust and chips, ensuring clean air in the workrooms, and avoiding health, fire and explosion risks. All scientific backgrounds of these problems are not fully known today, and efforts should be made to fill this gap. The work contains significant new derivations and calculation methods and experimental results to support design and evaluation methods such as particle size distributions depending on wood species and machining, terminal velocity of small wood particles, aerodynamics of suction hoods, a detailed analysis of particle separation in cyclones, selection and evaluation of separation efficiency for appropriate filter selection, energy consumption and transportation efficiency of pneumatic conveying, a comprehensive theory of transport ventilators. Several new details of dust explosion are also included. The calculation methods, practical solutions and recommendations are supported by physically well-established explanations providing long-lasting knowledge.
