“…The number of tubes (n) and their length (L) are constant and equal to design data (Tables 1 and 2). The heat transfer area is given by Equation (11). A constant length of the condenser was assumed, since it is defined by the length of the LP part of the turbine.…”

Abstract:The diameter and configuration of tubes are important design parameters of power condensers. If a proper tube diameter is applied during the design of a power unit, a high energy efficiency of the condenser itself can be achieved and the performance of the whole power generation unit can be improved. If a tube assembly is to be replaced, one should verify whether the chosen condenser tube diameter is correct. Using a diameter that is too large increases the heat transfer area, leading to over-dimensioning and higher costs of building the condenser. On the other hand, if the diameter is too small, water flows faster through the tubes, which results in larger flow resistance and larger pumping power of the cooling-water pump. Both simple and complex methods can be applied to determine the condenser tube diameter. The paper proposes a method of technical and economic optimisation taking into account the performance of a condenser, the low-pressure (LP) part of a turbine, and a cooling-water pump as well as the profit from electric power generation and costs of building the condenser and pumping cooling water. The results obtained by this method were compared with those provided by the following simpler methods: minimization of the entropy generation rate per unit length of a condenser tube (considering entropy generation due to heat transfer and resistance of cooling-water flow), minimization of the total entropy generation rate (considering entropy generation for the system comprising the LP part of the turbine, the condenser, and the cooling-water pump), and maximization of the power unit's output. The proposed methods were used to verify diameters of tubes in power condensers in a200-MW and a 500-MW power units.

“…The results indicate that the sensitivities of energy and exergy values and the results of energy and exergy analyses to reasonable variations in dead-state properties are sufficiently small. Erdem et al [14] analyze comparatively the performance of nine thermal power plants under control governmental bodies in Turkey, from energetic and exergetic viewpoint. The considered power plants are mostly conventional reheat steam power plant fed by low quality coal.…”

Abstract-Power industry is one of our basic industries, the development of the national economy and national security as well as energy has a very close relationship, and with the continuous development and progress of society, the status of the power industry is becoming increasingly important. However, in the power industry in the production process, there is an important and very worth considering is the production of security management. As we all know, to achieve the maximum benefit of the enterprise foundation is safety, if a security incident, it will have to reduce external power supply, increase the variety of expenses, the result is to make the rising cost of doing business, economic decline, and the personal safety of enterprise workers have to less than reliable guarantee, therefore, the power companies, strengthen safety management work is necessary. In this paper, the concept of power production from its scope, analyzes the common problems of electricity production and performance, build power production safety management, and discuss measures to strengthen the new power production safety situation management.
