but). Recalculation of wood waste volumes [46].

Recalculation of volumes of wood waste from storage or bulk measure to dense.

Different types of wood waste, collected and laid in a certain order, occupy a large volume compared to the volume that the same waste occupied in a dense mass.

The ratio of the storage density of wood waste to the density of wood (with the same moisture content) is called the fill factor of the overall volume or the wood density coefficient. The coefficient of full wood (Кv) is given in table

The volume of wood waste in a dense mass, m3, is determined by the formula:

Vpl. = Vcl. • K

where: VCL. - the volume of waste measured in storage;

Vpl. - volume of waste, measured in dense mass.


Bulk weight and wood content of shredded wood materials [1, 46]

With a decrease in particle size from 200 to 40 microns, the bulk bulk density of dust increases from 100 to 250 kg / m3.

b) Recalculation of the mass of wood waste from the storage measure to dense:

where mskl. is determined by the table.


Mass of firewood by species [19, 45]

where: Рт.н.т. - amount of wood waste, expressed in tons of natural fuel;

- the bulk density of dense wood of the corresponding breed (kg), is determined by the table.


Bulk weight of wood of various species [1]

d). Determination of the load factor of the aspiration system.

The determination of the total amount of wood dust through the maximum concentration of the pollutant and the volume flow of the gas-air mixture per unit of time without taking into account the load factor of the aspiration systems leads to an overestimation of the results. Often, when drawing up reports on form 2 TP (air) this factor is not taken into account. Therefore, when determining the gross emission of wood dust, it is reasonable to take into account the load factor of aspiration systems. The usable volume of aspiration air is the one that is removed from the working body when crushed waste is released [1, 3].

For each aspiration system determine the load factor:

where: Qvi is the air flow rate for each suction of the process equipment connected to the system, m3 / hour;

T is the system operation time;

ti is the operation time of the equipment (each organ of the process equipment), hour.

Experimental studies conducted by Ivanovo VNIIOT have shown that the annual load factor of the aspiration systems is approximately equal to 0.4 - 0.5. Thus, on average 50% of air is sucked off by existing suction systems from woodworking workshops for a year, and air from all equipment is removed, regardless of the actual simultaneity of work.

Appendix 2.2.7.

The content of free phenol, formaldehyde, acetone in adhesive materials used in the production of particleboard, plywood furniture, joinery and construction products [9, 11, 12, 13, 14, 15, 21, 22, 23, 35, 40, 41, 47, 48, 53, 54]

  1. Develop an appropriate annotation approach
    In order to make the best use of your abilities for annotation, it is important from the outset to ensure that your mind map is composed of a clear structure throughout the annotation process. One of the best approaches to annotating books should be considered the method of organic learning through mind maps, described in detail by Tony Buzan in his book.
    OBJECTIVE OF THE EMPLOYMENT: To master the method of calculating and using the compliance criterion for determining the reliability of discrepancies between several compared groups of studied phenomena. METHOD OF CONDUCTING THE SCHOOL: Students independently prepare for practical work according to the recommended literature and perform individual homework. The teacher checks for 10 minutes
  3. Rule number 1. You need to dress in accordance with the type of your figure.
    Believe me: having applied eight simple rules to your wardrobe, make-up and hairstyle, you will enjoy your reflection in the mirror every day. There is a classification of types of figures based on the skeleton structure, distribution of muscles and adipose tissue, body proportions and its lines. And it does not matter at all whether your Rubenso forms are or you are more likely to look like the Twiggy mannequin. Can get better or
  4. “Compliance of the basic characteristics of certain types of elites in the modern Russian society with a theoretical model”
    The fifth chapter consists of three sections, which examine the main typologies of elites, reflected in the social sciences at the present stage, common and specific in the psychology of the political, business and cultural-intellectual elites, as well as the correspondence of the psychological characteristics of modern Russian elites to the theoretical model. There are several approaches to the typology of elites: 1)
  5. . Forced slaughter of animals in your farm (place and method of slaughter, causes and ways of selling meat, compare with the current rules and draw the appropriate conclusions).
    The village "Chartaly" is located in the Omsk region in Tyukalinsky district. In sec. Chartals is a slaughterhouse. Cattle slaughter and carcass cutting consist mainly of the following operations: stunning, bleeding animals, shooting the skin or freeing it from hair, separating the head and limbs, removing the insides, sawing and toilet of the carcass. In the village "Chartaly" of animals (large
  6. Organization of sections
    The book is divided into six main sections. 1. Natural architecture In this section you will get acquainted with the most up-to-date information about the human brain, its structure and functions. You will see that many of the great thinkers of the past (called in this book just as great brains) used abilities that, with the right approach to business, are available to each of us. Thereafter
  7. The main sections of psychology
    In this chapter we got a general idea of ​​the nature of psychology, having considered its subject, the main approaches and methods of research. Now we can expand our understanding and find out what professional tasks representatives of various sections of psychology solve. About half of specialists with degrees and degrees in psychology work in colleges and universities. Besides

    Treatment of specific dyslipidemia. Very high LDL cholesterol (~ 190 mg / dL). Persons with very high LDL cholesterol usually have genetically determined forms of hypercholesterolemia: monogenic familial hypercholesterolemia, a family defect of apolipoprotein B, and polygenic hypercholesterolemia. Early detection of these disorders in young people is necessary to prevent premature development.

  16. Conclusion to the section "Sexual Culture and Health"
    Of course, you noticed that in the second section, unlike the first, there were very few questions after the chapters. Why? Because the problem of intimate life to discuss aloud is not easy. The line between sexological concepts and everyday sex-related conversations is very thin and easy to cross. And such a transition can be offensive to some individuals. But
    Approximately 2/3 of the water is inside the cells (intracellular water space), 1/3 outside the cells (extracellular water space) (Table 19.1). Table 19.1.

    Article 55. International Treaties. If an international treaty of the USSR establishes other rules than those contained in the USSR legislation on health care, then the rules of the international treaty apply. The same procedure applies in case of discrepancy between the legislation of the Union Republic and the international agreement concluded by it.

    1. Atrial flutter, regular and irregular forms In the above example of atrial flutter, the functional atrioventricular block was constant 5: 1 and did not change when the ECG was recorded. Four waves of atrial flutter were blocked, and only the fifth wave of flutter overcame the atrioventricular junction, passed to the ventricles and aroused them. In reply
  20. Additional information to the section
    1. Varieties of atrial fibrillation Atrial fibrillation can be large- and small-wave depending on the amplitude of f-waves. Small wavelength flicker occurs with greater frequency (about 600 per minute) and wave amplitude of not more than 0.1 mV. With large-wave blinking, the pulse frequency is 450 per minute, and the wave amplitude is about 0.2 mV. Some authors highlight the mid-wave twinkling.
