By signing international declarations and conventions, Bosnia and Herzegovina undertook to promote the production of energy from renewable sources, including wind energy. Designing a wind turbine system at a location requires knowledge of information about wind characteristics and resources, including information about turbulence. A wind energy pot...
The development and use of thermal power plants today is characterized by great complexity. Any disruption of the operating regime of such a plant is reflected in the power system. Since in the energy industry of the Western Balkan countries, the entire system of tasks and direct paths for achieving optimal reliability of a certain plant during exp...
The quality of maintenance of industrial systems is a measure of the success of planning, monitoring and implementation of the maintenance process. Monitoring quality in maintenance means recording and eliminating all anomalies that lead to undesirable phenomena such as violations of the optimal technical condition of equipment, inadequate quality...
Maintenance in the industrial system aims to implement activities
related to ensuring the correct working condition of work tools (machines and
devices) but also the accompanying infrastructure, which also includes industrial
buildings (production halls, warehouses, administrative buildings, boiler rooms,
etc.). Adequate and functionally correct in...
Biomass, in addition to being used for heating purposes in households, is increasingly used for the production of electricity, as well as liquid fuels for motor vehicles. Similar to other renewable resources, the analysis of the possibility of using biomass (theoretical, technical and economic potential) should include a systematic analysis of avai...
Historically, the use of wood-based biomass as the primary and almost the only source of energy preceded the beginning of the use of fossil fuels. Developing countries still have biomass as a source of thermal energy, with the big question of its sustainability. Unlike countries in transition, developed countries produce a significant amount of the...
Given the expected energy shift in Europe toward renewable energy sources and cleaner technologies, the issue of efficiency of thermal power plants (especially condensing thermal power plants with coal as the main fuel within the power system), in addition to analyzing the potential for increased energy efficiency and operational flexibility, requi...

At the level of design of thermal power plants (TPP), when making decisions related to the choice of its macro location and micro location, disposition solution and equipment structure, the choice of the right decision method is of particular importance. Multi criteria analysis involves solving inadequately structured problems, while in practical t...
Maintaining energy systems by estimating their condition, as a more recent approach to the maintenance problem, involves making database-based decisions that contain a certain amount of uncertainty, then qualitative estimates and numerical data obtained. Such a demanding approach to maintenance determines the need for regular inspections and monito...
Direct research on large and complex systems, such as thermal power plants (TPPs), is generally difficult and sometimes impracticable, especially at the stage of their planning, design, and installation and commissioning. To facilitate the study of such systems, a modeling method is often used, whereby a real plant is replaced by its model and then...
Modern and market-oriented hygienic paper production systems require a high level of reliability and readiness of the technical plant.

The analysis and monitoring of reliability level, as a specific project task, are conducted through all stages of the life cycle of a steam turbine plant. Analysis of the reliability of components or the entire technical system requires the application of models, which can be graphical or mathematical. A mathematical model is required in order to b...
Determining the reliability of a thermal power plant as a whole or in its individual components often requires long and very expensive tests under special operating modes on a very large number of samples or gathering the required exploitation data, which is even more difficult because of the choice of a general mathematical method (different forms...

Economic development of a country requires the consumption of appropriate energy resources. Any deviation from the timing as a result may have the appearance of development restrictions in the other economic activities, so the development of energy consumption should be continuously monitored. On the other hand, energy consumption itself is linked...

Riječ energija nastala je od grčke riječi energos što znači aktivnost. Energija je karakteristika sistema kojom se opisuje njegova sposobnost tog da vrši neki rad. Prema međunarodnom SI-sistemu mjernih jedinica, u čast engleskog fizičara James Prescott Joule (1818÷1889. god.), mjerna jedinica za energiju nazvana je džul (J). Kao takva ona je aditiv...
Energija, kao svojstvo sistema predstavlja skalarnu fizikalnu veličinu mjerenu u džulima (1 J = 1 kgm/s 2). Kao takva ona je aditivna, a ukupna energija, pri čemu je zbir svih energija svih sistema u svemiru konstantna veličina. Veza čovječanstva i projekcija njegove sudbine u budućnosti povezana je sa energijom. Osnova koja definiše rast svakog dr...

Riječ geotermalna dolazi od grčkih riječi geo (zemlja) i therme (toplota). Pod pojmom geotermalna energija smatra se ona energija koja se može pridobiti iz Zemljine unutrašnjosti i koristiti u energetske svrhe. Po svojoj prirodi, geotermalnu energiju se može smatrati i obnovljivom i fosilnom energijom, jer nastaje polaganim prirodnim raspadom radio...
Energetski resursi su glavni pokretač i snaga razvoja ljudske civilizacije. Porast broja stanovnika u svijetu i povišenje nivoa konfora života ljudske populacije i razvoj tehnologije i potrošnje energije su međusobno zavisni. Potrebe za energijom u 19. vijeku bile su veoma skromne, prve kompanije u SAD za proizvodnju gasa i nafte formirane su 60-ih...
Energetske potrebe trenutno se uglavnom podmiruju iz konvencionalnih izvora energije (fosilna goriva: ugalj, nafta, prirodni gas, hidroenergija vodotoka-hidroelektrane, kao i nuklearna goriva za procese fisije). Kako fosilna i nuklearna goriva spadaju u grupu neobnovljivih izvora energije, samim tim i njihove rezerve su ograničene, pa je neophodno...
