Dust Extraction and Handling in the Wood Industry (SpringerBriefs in Applied Sciences and Technology)

by Endre Magoss György Sitkei Zoltán Kocsis

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.

Dust Explosions

by Jean Cross Donald Farrer

The interest of the media in dust explosions increased considerably following two major grain-elevator disasters in the United States in 1979. However, these were not isolated incidents and were statistically unusual only in the high loss of life involved. Any oxidizable material that is dispersed in fine powder form may be explosive, and ignition sources with sufficient energy to ignite a dust cloud are easily produced in normal industrial processing. Dust fires and minor incidents are not uncommon in many industries, but fortunately the combination of events and circumstances that must coincide for a large-scale explosion arise only rarely. Nevertheless, this is often more by luck than by good management and many potentially hazardous situations are common in industry. An explosive dust cloud and the circumstances in which it can ignite are not as simple to define as the equivalent situation in gases or flammable vapors. A large number of definitions and experimental tests have been devised to characterize the explosibility of dusts and ignition sources. The aim of this book is to provide a guide describing conditions in industry that could lead to dust explosions and the means to avoid them. Ignition sources and the way in which they can arise in powder processing are discussed and illustrated by case histories of reported incidents. The methods by which the potential hazards of a process or product can be evaluated are described, with special attention paid to the interpretation of the results of the different experimental methods.

Durability of Strain-Hardening Fibre-Reinforced Cement-Based Composites (RILEM State-of-the-Art Reports #4)

by G. P. A. G. Van Zijl F. H. Wittmann

Strain-Hardening Fibre-Reinforced Cement-Based Composites (SHCC) were named after their ability to resist increased tensile force after crack formation, over a significant tensile deformation range. The increased resistance is achieved through effective crack bridging by fibres, across multiple cracks of widths in the micro-range. Whether these small crack widths are maintained under sustained, cyclic or other load paths, and whether the crack width limitation translates into durability through retardation of ingress of moisture, gas and other deleterious matter, are scrutinized in this book by evaluation of test results from several laboratories internationally. The durability of SHCC under mechanical, chemical, thermal and combined actions is considered, both for the composite and the fibre types typically used in SHCC. The compilation of this state-of-the-art report has been an activity of the RILEM TC 208-HFC, Subcommittee 2: Durability, during the committee life 2005-2009.

by Carmen Andrade Joost Gulikers Rob Polder

This book presents key advances in the modeling of reinforcement corrosion and concrete durability. It also examines various further aspects of reinforcement corrosion and concrete durability, striking a balance between modeling and testing. Particular attention is paid to innovative treatments for avoiding deterioration, and to methods for modeling performance in a real environment. Some basic aspects related to non-destructive testing techniques are also discussed. Deterioration-related topics addressed in the book include the basis for modeling alkali-silica reactions, chloride diffusion and the development of concrete microstructure; measurement-related topics include cathodic protection, polarization resistance and resistivity. A combined approach using the AFM technique and polarization measurements is examined, and the relation between cracking and corrosion and the treatment of concrete with hydrophobes or innovative products such as hydrotalcite is also discussed.

Durability of Industrial Composites

by Antonio Carvalho Filho

Durability of Industrial Composites offers numerical and quantitative solutions to long-term composite failures that are useful to practicing engineers, researchers, and students. All modes of laminate long-term failure are contemplated, with resin toughness and environmental conditions considered. The book develops a simple unified equation to compute the load-dependent durability of laminates under the simultaneous action of cyclic and static loads. The load-independent durability and residual life of equipment immersed in corrosive chemicals are also discussed. The book presents a full discussion of the elusive strain-corrosion mode of failure as well as a complete solution to the durability issue of underground sanitation pipes. The currently accepted durability parameters of HDB, Sb and Sc are discarded as incorrect and replaced with the appropriate threshold parameters. The entirely new concept of the "anomalous failure" is fully discussed and solved. The effects of overpressure and spike strains, as well as of the operating temperature and moisture, are quantitatively evaluated and illustrated in numerical examples.
