Modeling and analysis of optimal performance of a coal-fired power plant based on exergy evaluation
Energy Reports, 2022 One of the ways to minimize fossil fuel consumption is to optimize the feedwater heaters of the power plants. The newly-built power plants work optimally at their design conditions; however, by aging, they often deviate from those conditions.

Transient Stress Analysis of High Pressure Heater During Feedwater Bypass Regulations
发电技术, 2019 The safety of equipment under flexible operation is an important issue in the deep peak shaving process of coal-fired power plants. As large-scale, high-temperature and pressure-bearing heat exchangers, high-pressure heaters play an important role in the

A Case Study of Feedwater Heater Life Management [PDF]
Journal of Pressure Vessel Technology, 1998 In the late nineteen eighties, electric utility companies, such as Kansas City Power and Light (KCPL), recognized the viability of extending the life of power plants by repairing or replacing major components instead of building entirely new facilities. As part of a strong life management program, a life evaluation can postpone the replacement of major
