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.
