Prevent Corrosion in Cooling Towers: Finding the Optimum Amount of Makeup Water and the Outlet Water Stream, Experimentally

European Journal of Technology and Design, 2015, Vol.(7), Is. 1, pp. 4-11.
DOI: 10.13187/ejtd.2015.7.4CrossRef

In this work, problems related to the corrosion and sedimentation in cooling tower and the decrease in the amount of evaporation rate are investigated experimentally, using loop test which is similar to the cooling tower system. The input and output water stream in the loop test are analyzed in different time intervals, different amount of evaporation, different amount of the outlet water and make up water stream. The first analyzes indicate on the increase in the amount of dissolved material, concentration cycle and also the increase in the amount of evaporation rate and consequent corrosion problems and sedimentation. However, adjusting the amount of makeup water and the water outlet provides the acceptable results. Changes in conditions due to each analyze are illustrated in curves.

Parametric Study of Basic Items in the Solar Still

European Journal of Technology and Design, 2015, Vol.(7), Is. 1, pp. 12-15.
DOI: 10.13187/ejtd.2015.7.12CrossRef

Fortunately, in regions of greater potable and drinking water shortage like Middle East, renewable energies such as solar energy is more abundant during the year. The desalination method in this solar desalination still is evaporation distillation. Basically this solar desalination still is a batch stage for every day operation with saline wastewater. This paper describes the solar desalination still, discusses the used method for distillation and represents the experimental results, finally. The results show the feasibility of using the solar still.

Automation Systems Inlet air of Laboratory Campus

European Journal of Technology and Design, 2015, Vol.(7), Is. 1, pp. 16-26.
DOI: 10.13187/ejtd.2015.7.16CrossRef

In the work there were reconstructed the HVAC system of laboratory campus on Tchaikovsky. There was proposed an automated system management through ventilation systems, which enables savings energy-resources, protect the motor from overheating and heat exchangers from freezing. The calculations showed that the introduction of automation annual economic benefit of 150,854.62 rubles.

Modeling of Combustion of Watered Gasoline

European Journal of Technology and Design, 2015, Vol.(7), Is. 1, pp. 27-35.
DOI: 10.13187/ejtd.2015.7.27CrossRef

With helping of soft "Thermodynamic" there was numerical researching of the thermodynamic combustion's parameters of watered gasoline for conditions of carbureted engine as function of coefficients of oxidizer's surplus and water ballast. It is shown that the water ballast of about 5 % can be useful, as it gives a stoichiometric combustion of nearly 10 percent increase in RT while reducing the CO by 42 %.

Primary Hydrocarbons on the Power Plants for Oil's and Gas's Production

European Journal of Technology and Design, 2015, Vol.(7), Is. 1, pp. 36-48.
DOI: 10.13187/ejtd.2015.7.36CrossRef

This paper presents an informative review of power plants in oil's and gas's production, construction and the main characteristics are discussed. There were analyzed, and there were produced the comparison and the selection of the optimum parameters of the power plant. The work can be used for create a prototype of power plant using purified APG.
