Abstract

An important scientific and technical problem of increasing the efficiency of CHP steam turbine units through the optimization of their operation modes and the creation of new highly efficient flow parts of cogenerating turbines is solved. Solutions to the problem of rational distribution of heat loads between the network heaters of cogeneration turbines during the heating period are presented. The calculations were performed using the software package SCAT which was developed in IPMach NAS of Ukraine. The carrying out of calculations of three-dimensional turbulent flows in flow parts of turbines using modern software systems is an effective direction of increased efficiency of power equipment. For the numerical research of three-dimensional currents, steam in the flow part of the steam turbine software package IPMFlow which is developed in IPMach NAS of Ukraine is used. With the use of software package IPMFlow, the researches of three-dimensional currents steam in the flow part of the medium pressure cylinder of the steam turbine of series T-100-130 are carried, which showed the feasibility of optimizing the geometry of the flow part in order to improve gas-dynamic characteristics of blades apparatuses.

热电联产发电厂大型机组热电联产汽轮机供热方式及设计优化

解决了通过优化热电联产汽轮机组运行方式和创造新型高效热电联产机组流动部件来提高热电联产机组效率的重要科技问题。提出了热电联产机组供热期热负荷合理分配问题的解决方法。利用乌克兰IPMach NAS开发的SCAT软件包进行计算。利用现代软件系统进行涡轮流动部件的三维湍流计算是提高动力设备效率的有效方向。对于三维流的数值研究，使用的是乌克兰IPMach NAS公司开发的汽轮机软件包IPMFlow中流动部分的蒸汽。利用IPMFlow软件包对T-100-130系列汽轮机中压缸流动部分的三维电流蒸汽进行了研究，证明了优化流动部分几何形状以改善叶片装置气动特性的可行性。
