Journal Title: Сучасний стан наукових досліджень та технологій в промисловості - Year 2017, Vol 2, Issue 2
Abstract
The subject matter of the study is the economic efficiency of modernizing equipment for thermal power plants (TPP). The goal of the study is to identify the economic efficiency of modernizing the equipment of the TPP basing on new technology and taking into account cost minimization and environmental requirements. The subject of the study is the theoretical and practical aspects of the economic efficiency of equipment modernization. To find a solution of this problem, the feasibility analysis was used to determine the current state of TPP equipment and the indicators of the parameters of old and new equipment as well as to introduce new equipment, which enables burning low-grade and waste coal in a circulating fluidized bed (CFB). The issues of energy as the industry that covers energy resources, extraction, transformation, transfer and use of various types of energy are considered. The features of an electric power station, as a set of installations, equipment and tools which are used directly for producing electric energy are highlighted as well as the necessary facilities that are located on a designated area. The features of the structure of the technology of thermal power plants are illustrated. The place of thermal power plants in the structure of power engineering is considered. The available problems of thermal power plants are revealed. The solution of problems of low efficiency, the deterioration and ageing of thermal power plants equipment is suggested. The indicators of the equipment of thermal power plants are given. The advantages and disadvantages of the old technologies used in thermal power plants of Ukraine are studied. The disadvantages of outdated equipment such as damage and constant need for reconstruction are regarded. The mechanism of introducing the new technology of the circulating fluidized bed (CFB) in comparison with the traditional flaring at domestic and foreign thermal power plants is analyzed. The advantages and disadvantages of the CFB technology in comparison with traditional flaring are considered. The results of the feasibility study are presented; these results provide the basis for determining the most promising objects for the implementation of this technology while retooling power plants. The effect of modernizing the equipment of thermal power plants is proved. Solutions for improving the cost-effectiveness of thermal power plants are suggested. The results of the obtained decision within this study are illustrated.
