A major problem in the area of the city of Sarajevo is that during the winter period there is an increase in the concentration of harmful gases in the atmosphere (primarily CO2), as a result of the intensive use of fossil fuels. Constant growth of energy sources, then the increase in the price of electricity and the intensification of the effects of greenhouse gases is the main reason for the analysis of wind potential in the area of the city of Sarajevo. In this paper analyzes and processes wind velocity data for the period from 2001 to 2010 for the area of Sarajevo, obtained from the Federal Hydrometeorological Institute of Bosnia and Hezegovina. After analyzing and processing wind velocity, a more precise assessment of wind potential in the Sarajevo area was given and guidelines for further research.

The mixing equipment is made of two main elements: an upper premixer consisting of two bolted parts. This premixer is lined with melted basalt plates on all sides where the wall of the equipment the built-in cone-deflector and the support elements of the cone is in contact with the slurry. This conditioner tank is made of wear-resisting hardox plate. Basic characteristic of this technology is mixing water with fly ash and bottom ash in ratio 1:1 and like dense slurry, with high pressure pumps, transported by pipeline to the disposal area. The essential characteristic of this technology is that it makes maximal use of the intrinsic property of ash, which tends to solidify in contact with water forming a steady and stable completely ambient-neutral rock mass.

In this paper, wind energy potential in Sarajevo area, Bosnia and Herzegovina, was analyzed statistically. The analysis of wind energy potential was performed based on measured wind data in a one-year period from 1 January to 31 December 2019. Measured data were obtained on the basis of a meteorological station installed on the roof of the building of the Faculty of Mechanical Engineering in Sarajevo at 30 m height. Measured wind characteristics were statistically analyzed using the Weibull and Rayleigh distribution functions. The Weibull parameters were obtained using two methods, the energy pattern factor method and the maximum likelihood method, and both methods were used to find the Weibull parameters and the wind power density. The results of this investigation showed that the analyzed place falls under Class 1 of the international system of wind classification as the mean annual wind velocity recorded in the analyzed area was 1.215 m/s and the corresponding annual mean power density was estimated to be 6.7 W/m 2 at 30 m height. The results show that the available wind energy potential to generate electricity in Sarajevo is low and wind power cannot be used to meet the energy needs in that region.

Constant growth of energy sources, then the increase in the price of electricity and the intensification of the effects of greenhouse gases is the main reason for the analysis of wind potential in the area of the Canton Sarajevo. In this paper analysis wind velocity data for the period from 2000 to 2010 for Bjelasnica, obtained from the Federal Hydrometeorological Institute of Bosnia and Herzegovina. After analysis wind velocity, a more precise assessment of wind potential in the Bjelasnica area was given and guidelines for further research.
