And Storage

Kosovo’s waters are unevenly distributed in time and space. Kosovo is water scarce, and it also has the low level of water resources development and storage. In particular Iber basin is water stressed, but in the next 20 years it is expected that all Kosovo’s basins will be water stressed [1]. This is due to population and general economic growth, and resource variability. The anticipated revitalization of the irrigation and mining sector and additional demands from the energy sector will increase pressure on new water demands [5]. For these reasons, the water quality of existing resources will become an ever-growing problem if not addressed now. The lignite-fired power plant “Kosovo B” is main the energy source in the country. The wastewater produced from its operation is discharged into Sitnica river with minimum treatment. With study of pollution level of wastewater discharges, this article sets several recommendations for treatment of wastewater in order that power plant meets national and EU operation requirements.

The paper evaluates the presence and content of traces of heavy metals Hg, Pb, Ni, Cd (total forms) from coal and solid combustion products, the degree of transfer and accessibility in the area of influence of a lignite power plant. The content of toxic heavy metals in residues are characterized by RE Meiji [ 1 (Pb and Hg) and REMeij �1 (Ni and Cd) for the filter ash. Pb and Ni content in the soil exceeds normal values, and Pb exceeds and alert value for sensitive soils around the residue deposit (70.20 mg.Kg-1). The degree of accessibility of the metals in plants (TF), reported at the Khan reference value (0.5), indicates a significant bioaccumulation level for the metals: Cd (1.9) and Hg (0.6) inside the deposit; Cd (0.39) at the base of the deposit, Hg (0.8) in the area of the thermal power plant. The trace levels of heavy metals analyzed by GFAAS and CVAAS (Hg), indicates a moderate risk potential for food safety and quality of life in the studied area.

Assurance System

The most critical component of a wind power plant is the transmission line, which carries two key tasks – the transpor-tation and distribution of electricity. The transmission line is also responsible for the various substations, wind power stations to contact to its safe and smooth operation. As the competition order of wind power projects is more chaotic, the quality of the project cannot be supervised and controlled by the whole process. The quality control of the project is not up to standard, and the overall quality of the transmission line will be affected. This paper focuses on two aspects of the elaboration, one is the wind turbine transmission line project common quality problems; the other is how to build wind power plant transmission line quality assurance system.

Main Motive

All companies are dependent on their raw material providers. The same applies in the case of thermal power plants. The major raw material for a thermal power plant is the coal. There are a lot of companies which in turn provide this coal to the thermal power plant. Some of these companies are international; some are local, whereas the others are localized. The thermal power plants look into all the aspects of the coal providing company, before settling down for a deal. Some people are specifically assigned to the task of managing the supply chain. The main motive is to optimize the whole process and achieve higher efficiency. There are a lot of things which a thermal power plant looks into before finalizing a deal, such as the price, quality of goods, etc. Thus, it is very important for the raw material providers to understand each and every aspect of the demands of the thermal power plant. A combination of three methods—Delphi, SWARA, and modified SWARA—has been applied to a list of factors, which has later been ranked according to the weight and other relevant calculations.

Time Of Year

The behaviour of 137Cs from the Chernobyl nuclear power plant accident in the Ukraine on 26 April 1986 was monitored during a 3-year period in the canopy of a young Scots pine (Pinussylvestris L.) stand in southern Finland. Needle samples were collected from the same whorls on 13 sample trees marked at the beginning of the study. The 137Cs activity of throughfall water was determined in summer 1986. The oldest needles at the time of the radioactive deposition (formed in 1983) had the highest l37Cs activity (20 000 Bq/kg) in June 1986, when the monitoring was started, 58 days after deposition. About 50% lower 137Cs activity was observed in the needles formed in 1984 and 1985, and an even lower activity of 3050 Bq/kg in the needles formed in 1986 following the incident. During the summer of 1986, the 137Cs activity of the whole canopy decreased from 106 000 to 42 500 kBq/ha, corresponding to a weathering half-life of 72 days. Washout by throughfall accounted for 79% of the decrease, while the rest was mainly due to the gradual shedding of the highly contaminated 1983 needles. The needles formed in the summers of 1987 and 1988 had rather high 137Cs activities of 2700 and 4800 Bq/kg, respectively. The reduction in the 137Cs activity of the canopy was considerably less in 1987 and 1988, with weathering half-lives of 435 and 242 days, respectively. The total 137Cs activity of the canopy was still 13 500 kBq/ha on 20 October 1988, which was 896 days after deposition. An increase in the 137Cs activity was observed in the autumns 1987 and 1988, and to a lesser degree in the autumn of 1986, a time of year when needle potassium concentrations normally tend to increase. It was concluded that the Chernobyl 137Cs had become mixed with the chemically analogous K, and was recirculated within the trees together with K.

Operational Tests

In order to evaluate the performance of new turbo gas power plants for putting in commercial operation, it was necessary to supervise, test and, if so the case, to approve the works of commissioning, operational and acceptance of all equipments and systems that constitute the power plant. All this was done with the aim of guaranteeing the satisfactory operation of these elements to accomplish the function for which they were developed. These activities were conducted at the request of the customer to confirm and observe that the evidence of the tests was carried out according to the specifications and international regulations. The putting into commercial operation activities were done in collaboration with the supplier and manufacturer of equipment, the client and the institution responsible for certification and approval of the plant. All this in a logical and chronological order for the sequence of commissioning tests, operation and acceptance. Commissioning tests were carried out on-site at normal operating conditions, according to the design and operation needs of each power plant of a group of 14. Once the commissioning tests were completely executed and in a satisfactory manner, operational tests of the plants were developed. This was done by considering that they must operate reliable, stable, safe and automatically, satisfying at least, one hundred hours of continuous operation at full load. After evaluating the operational capacity of the machine, it was necessary to determinate the quality of the plant by carrying out a performance test. Finally, it was verified if every unit fulfills the technical requirements established in terms of heat capacity of the machine, noise levels and emissions. As a result of this process, it is guaranteed to the customer that the turbo gas power plants, their systems and equipments, satisfy the requirements, specifications and conditions in agreement with the supplier and manufacturers referring to the putting into commercial operation of the plant.
