International Energy Agency

The Fuel and energy complex is the foundation of modern society. From his work effectively depends largely on the welfare of society, the activities of all other sectors of the economy and the country’s position in global society. According to experts, it is expected that in the next 30 years worldwide will increase significantly the demand for energy of all kinds. At the same time on the conclusions of the International Energy Agency, oil and natural gas maintain its leading position. Click Gary Kelly to learn more. It is assumed that Russia’s position as the world’s leading exporter of energy to be reinforced. Fuel and energy complex combines the industry, which mines and produces primary energy, recycle them into other forms of energy, as well as different types of energy transported by specialized transport (pipelines, power lines, the thermal conductivity). From this derive the various structures, such as: the production pipeline components, construction of various oil and gas complexes, etc. Currently, oil and gas centers are concentrated in Western Siberia, Volga, Urals, North European part of Russia. For even more details, read what Verizon says on the issue.

Proved oil reserves in Russia are estimated at 25 billion tons and natural gas in 48 Trill. m3 – these are real opportunities for economic development and exports. The bulk of oil and associated gas produced in Western Siberia, here and concentrate most of the enterprises producing steel flanges, fittings, reducers, elbows, tees, etc., as in Western Siberia is the main part refining facilities. In second place is the Volga, Urals and on the North European part of Russia. Restore the previous value of oil refining, but still have problems with depth of processing. Achieved a level of depth of oil refining lags well behind the world’s best achievements, significantly affected the quality of produced light oil, and they still fall short of the already adopted in several countries of the world standards euro 3 and euro.

Reactive Power Compensation

Overview of the generation and consumption of reactive power in electrical networks all the processes in electrical systems, it is common to characterize using three parameters: voltage, current and power P. However, for convenience of calculation and accounting of electricity is also used, and other options, including an option as the reactive power Q, which is used to create electric and magnetic fields, without which the work converting devices (transformers, various types of transducers and other devices) by virtue of their physical properties is impossible. In this case, the inductance consumes reactive power and capacity of its generating. Full power in ac circuits is the product of current I on the voltage U, and for three-phase ac circuits, it is equal to 1,2: S = V3IU = V (P2 + Q2), where S, P and Q – a full, active and reactive power, respectively, p – shift angle between voltage and current; cos (p – power factor is an indicator of reactive power consumption and showing the ratio of active power P and the total power of 5 (sozf = P / 5); thp – ratio of reactive power. It note that only the active power P, due to the transformation of the energy of the primary engine derived from a natural source, into electricity, can perform work and converted into useful mechanical, heat, light and chemical energy. As for the reactive power Q, it is not connected with the performance of useful work, but only spent on the creation of electromagnetic fields in electric motors, transformers, induction furnaces, welding transformers, chokes and lighting.

Foam In The Russian Market

In this article we'll discuss the variety and quality of foam in the Russian market. Foam produced by the following method: foam filled in some form in the form of blocks, or any of various forms. Correct to speak polyurethane (PUR), since foam – a trade name. In Russia (USSR), manufacturer of polyurethane foam has begun since 1960. There are 2 main methods for production of flexible polyurethane foam is a continuous and periodic. Currently, the production of foam rubber in Russia is about 70 tons per year. Foam density 25 kg/m3 and below is about ninety percent of the total volume produced block of foam. Such foam professionals worldwide attributed to the category of packaging, rather than furniture type.

Only some brands of foam with a density of 25 kg/m3 and below are used in the manufacture of children's furniture and backs of upholstered furniture. We must remember that when packing for the transport of almost all of produced foam decreases by 5 times. And after losing heavily in the promotion of quality. For example, high-quality polyurethane foam after the promotion has stiffness 3.2 kPa, instead of 4 kPa and the poor quality – less than an order of magnitude. Loss in stiffness after the compression is strongly decrease with increasing density of the foam. However, to produce 'heavy' foam is much more complicated than the 'easy'. Thus, a paradoxical situation.

Firms that manufacture polyurethane foam, it is advantageous to produce lightweight foam, and furniture manufacturers to make of it cheap, but the 'disposable' products. At this moment in Russia, most companies have limited ability to produce different grades of foam rubber: the number of polyol flow does not exceed 3, the number of additional chemical components of not more than ten. This undoubtedly affects the range of Russian foam. Only when the company following conditions can be achieved consistently high quality foam: 1. Treatment of foam should be carried out at the plant, equipped with hi-tech modern equipment, 2. Using raw materials for production of high quality. 3. The company must be provided with highly qualified staff, capable of using all the potential of the equipment. 4. High quality manufactured products in the enterprise must be maintained certified quality management system. Unfortunately, few Russian producers can boast of having the company set all of the above criteria. It is therefore necessary carefully analyze the advantages and disadvantages of a company before starting cooperation.


The shape of the profile also depends on how much, if properly mounted on finished roof visible vertical joints of sheets. Horizontal joints on the quality of metal are practically invisible, because they are in the area shaded in a higher crest. Therefore, ask the seller show pictures of roofs covered with metal tile selected profile. Pay special attention to the 'solidity' of the roof, ie, apparent lack of transverse joints sheets. The service life of the roof depends largely on from the coating of metal. Optimal coverage is by far the 'Puranas', based on a combination of performance and price. If you want to provide the greatest stability of the coating, advisable to choose 'PVF2'. And probably reasonable in this case, buying the most famous brand in the maximum configuration.

For those who are important to a complete absence of light on the roof (although the tiles of clay, which mimics metal, glitter is present), there's Matt polyester. " If you do not have any high demands for reliability, fit 'Polyester'. When choosing colors for future design of the roof are taken into account at home, the surrounding landscape and then which color you prefer. However, it must be borne in mind that the surface of metal dark colors on a hot sunny day, very hot. When properly made ventilation underlay space in the attic of a house with dark roof will be hot and stuffy.

The bright metal pollution more visible. Once you have chosen a particular kind of metal roofing for your home or have decided to fully trust Specialist advice will need to choose a company where you buy stuff. The same (in the sense, produced by the same factory) metalocherepitsu can be purchased from various retailers. We advise to buy there, which is cheaper, if the level of consultation, service, transparency, respect for you as an individual, personal approach to your project fit your needs. In this case, you can be sure that working with a company focusing on the long and competitive performance in this market. The service life of your roofing system is designed for decades. Who else but the seller must be all this time, a guarantor of quality the roof of your house? Another very important point. You should know that the life of a roof depends on the quality of its installation. Therefore, it is essential to the existence of the firm of the seller's own roofing crews and licensed practice of assembling metal. Even if you do its builders, this practice does counseling, guidance and responsibility of the chosen firm's real.

Scrap Metal Recycling

In metallurgy, as a branch of industrial production, recycled ferrous, precious and nonferrous metals, is their concentration, casting and rolling, produced the necessary metal alloys. Then there is metal, which resulted in manufactured metal products, billets and parts. Learn more at this site: Scott Kahan. The result of this process becomes a lot of waste and waste metals. Isolation of metals from ore is 75% more energy-consuming than the process of recycling scrap metal. Lawrence Ellison is not frequently seen there. Not difficult to guess that today "extraction" of black and nonferrous metals from the waste metal production easier and more profitable than processing ores.

A natural question arises: how to organize the production of the scrap metal, and most importantly how to ensure his full-time employment. To begin, you must purchase the equipment for scrap metal recycling: balers, alligator shears, etc. How to deal with congestion points? Workload depends on the sort incoming scrap, to which at first glance, it's hard. But it turns out that solution to the problem lies on the surface: it is required at the stage of the production of alloys of different metals to classify and suitable label. After the production of parts or pieces alloys are not subject to high-temperature melting, thus marking stamp will remain on the surface as long as the product is out of operation and will not be sent for recycling. Such a system greatly simplifies sorting and receiving of scrap metal, and therefore facilitates the definition of the ratio weight / scrap / cost. Marking of metallic alloys are widely used in engineering and other heavy industries. Introduction mandatory labeling will cause some inconvenience in the early stages of implementation, it is to some extent increase the cost of production, but in what surely will significantly reduce costs and simplify sorting the process of recycling scrap metal. Much easier and more profitable use of the sources of the metal that is not in the bowels of the earth, and under the arm. Processing of recyclable materials is much cheaper. However, the question remains open is than one decade.

Steam Power Electrode Boilers

Steam boilers controlled electrode designed to produce the vapor pressure of 0,6 MPa (6 kg / cm 2) and used for heating in residential and industrial premises, as well as for process steam supply agricultural, industrial and household objects. Symbol boiler: numerator – power consumption, kW, the denominator – nominal supply voltage, kV. For example, the symbol CEPD-250 / 0,4 stands for: Electrode Steam Boiler adjustable power output of 250 kW, a rated voltage of 0.4 kV Mains. In a steam boiler heat released during the flow of electric current through water, represents the resistance goes to its heating and evaporation, thus electrode steam boilers produce saturated par.V cylindrical body of the boiler is installed coaxial cylindrical shell with two cameras – steam-generating and Displacement. In the steam-generating chamber is a package of flat electrodes, which in current-carrying studs through the bushing in the bottom of the voltage is 0.4 kV three-phase mains. The water that fills the interelectrode space, forms the active electrical resistance included in the scheme of 'triangle'. The ends of the plate package electrodes are insulated from the outside dielectric plates to avoid unbalanced loads on the phases of the (skew). In the case of boiler feed water with low resistivity electrode system made of three cylindrical rods instead of flat. Displacement and steam-generating chamber are reported on the water at the bottom of the boiler on a pair of two chambers connected only via the temperature controller. Boiler construction provides automatic control in a given mode electric power boiler and, consequently, its steam.

Sleeve Filter

More and more we talk about environmental pollution, environmental problems and global warming. One of the reasons that these problems are exacerbated, the industry, more emissions are allocated to factories. At this each time the plant has the exact maximum level of emissions that it can release into the atmosphere if the emissions do not meet the requirements, followed by fines and sanctions. To capture harmful and / or unnecessary dust installed filters, and very often this bag filters. Bag filters can be used for two purposes: 1) to prevent ingress of atmospheric emissions of the production process and 2) the collection of products and return it back into production. It was in these filtration systems, such as filter elements, filter bags installed.

Sleeve filter may have different sizes (diameter and length), different arrangements for strengthening them in the filter, and their various modifications are dictated by what a regeneration system is applied in a particular installation. For example, in systems with impulse blowing (the surface of the sleeves brush away from nozzle dust momentum of air), typically used for hose frame basis with a weight of 500-600 g/m2, which makes the sleeve extra strength and durability. In the Shakers used the sleeves of the materials of 350-400 g/m2 because of flexibility. It is also lighter and more flexible materials used in the sleeves for systems with backflushing, their weight is usually in the borders of 400-500 g/m2. What materials are used in the manufacture of filter bags? Usually it is woven punched material from various synthetic fibers. The choice of fiber is determined by the environment and the process temperature. For example, for dry environments where the temperature neprivyshaet about 140 degrees Celsius, are used sleeve of nonwoven webs of polyester fibers.

On the other hand, if the environment is very acidic and the temperature reaches 270 degrees Celsius the only thing that fits, it's the sleeve of polytetrafluoroethylene. Also differ and the ways longitudinal joint sleeves. Most-seam stitching way but also can use the method of heat sealing. Heat seal is only possible if the sleeve of a material which melts at certain temperature (polyimide and polytetrafluoroethylene welding is impossible). There are many manufacturers of filter bags but only some of them are knowledgeable and experienced producers. For best kachnstva vyberat checked bags. More details on the sleeves and species you can find on the website Andrew Webron Limited, which is a manufacturer of nonwoven fabrics and filter bags.

First Consumers

Power consumers of the first and second categories are provided with electricity by means of two independent power sources, and special group of consumers of the first category – even through three. For more information see this site: David Fowler. The first category is switched to backup power automatically, the second translated manually. According to sep, subject to specified requirements The first group of consumers will be immune from such situations, when the power interruption could lead to a 'danger to human life, a threat to state security, a significant material damage, impairment of complex technological process, disruption of critical elements of public utilities, communication facilities and television. " Disabling the same from electricity consumers the second category, in this case would 'only' to 'mass Shortage in production, massive outages workers, machinery and industrial transport, disruption of a significant number of urban and villagers'. In other words, global catastrophe does not threaten us, but what do ordinary consumer? Just think – houses belong to the third group of power consumers, a break in the power supply which according to sep, could be delayed for a day! The answer is simple and neoriginalen. To protect themselves from harm associated with the sudden power outage, you need to install a backup power source. He, incidentally, provide additional kilowatts of power, the probability of which is reduced to almost zero. Taxonomy of autonomous sources of energy can be divided into two large groups. The first group includes units that convert other forms of energy into electrical energy, while their work does not depend on the main power supply system.
