Item Аналіз та оцінка впливу шкідливих викидів ТЕС України на навколишнє середовище(Видавництво Львівської політехніки, 2013) Коваленко, Тетяна; Коваленко, ПавлоThe development of science and technology continually affects the growth of human impact on the environment. Especially in our time, the problem of pollution of the atmosphere, lithosphere and hydrosphere and their negative impact on the biosphere, human life and health becomes more and more relevance in the world. Therefore, the analysis of current research and publications concerning the effects of emission of thermal power plants in Ukraine on the environment have been done in this work. The reasons that lead to the pollution of the biosphere were generalized and the ways to overcome this environmental problem were given. The main conclusions of the work were made according to the scientific research.Item Оцінка ефективності застосування загущеної присадками індустріальної оливи у вузлах тертя енергетичного устаткування(Видавництво Львівської політехніки, 2013) Коваленко, Тетяна; Івасик, ЯрославPolyfunctional lubricant performance properties indicates its significant impact on the longevity and efficiency of work of contact pairs. About 30% of the total energy produced is consumed to friction. The improvement of lubricant and efficiency of lubricating can reduce energy costs by 45%. Therefore, the correct choice of lubricant depends on energy consumption to overcome friction, wear of rubbing surfaces. The most economical way for the improvement of work of the friction units in different environmental conditions is the development of new lubricant compositions with the addition of an effective multifunctional additives as so base oils don't meet all of requirements put forward to them. The polymethacrylate additives with enhanced functionality were obtained in this work. The influence of the concentration of the additives on the viscosity-temperature, depressor and anti-wear properties of industrial oil I-20A were studied. Found that received additives improve the performance properties of oil-20A, respectively, contribute the reliable lubrication of the friction units in power plants at different natural conditions.Item Застосування в енергетичних установках загущеної присадками індустріальної оливи(Видавництво Львівської політехніки, 2011) Коваленко, Тетяна; Гарасим, АндрійОдержано багатофункціональні поліметакрилатні присадки та досліджено експлуатаційні властивості мастильної композиції загущеної оливи І-20А.
