Abstract

Higher fuel prices make it possible to minimize the unit costs of generating electricity. One way to reduce the cost is to reduce the cost of electricity produced and increase efficiency. This can be achieved through the introduction of combined cycle plants. The implementation of combined-cycle plants is carried out by combining the gas turbine and steam turbine parts with a common technological cycle. Thus, the gases leaving the steam turbine are a source of heat for the steam cycle. In this paper, a 110 MW CCGT unit is considered. The waste-heat recovery boiler as a connecting link is an important part of the power unit. Therefore, the study of its characteristics may affect the operating modes of other equipment. The aim of this work is to study changes in flow rate, pressure, high and low pressure temperature depending on the load of a gas turbine. Based on a computational study, an analysis of changes in the characteristics of the waste heat boiler under variable operating conditions is presented.

燃气轮机变工况对余热回收锅炉特性的影响研究

较高的燃料价格使发电的单位成本最小化成为可能。降低成本的一种方法是降低发电成本，提高效率。这可以通过引进联合循环装置来实现。联合循环装置的实施是通过将燃气轮机和蒸汽轮机部件结合在一个共同的工艺循环中来实现的。因此，离开汽轮机的气体是蒸汽循环的热源。本文以一台110mw的CCGT机组为研究对象。余热回收锅炉作为连接环节，是发电机组的重要组成部分。因此，对其特性的研究可能会影响到其他设备的工作方式。本工作的目的是研究流量、压力、高压和低压温度随燃气轮机负荷的变化。在计算研究的基础上，分析了不同工况下余热锅炉特性的变化。
