This paper performs a three-dimensional flow analysis and flow-induced vibration evaluation of a tube bundle for the low-pressure feedwater heater of a nuclear power plant. Using a commercial computational fluid dynamics software, CFX-4, a detailed shell side flow analysis model is first developed and the near-field cross flow around different ...

In order to ensure the safe and economic operations of thermal power plants, heater water levels of high pressure (HP) and low pressure (LP) heaters are important process variables to be monitored in industrial alarm systems. This paper proposes multiple factors affecting heater water levels, and the ways performing the root cause analysis for ...

Results obtained from equipping the drain pumps of low-pressure heaters used in a T-250/300-23.8 turbine unit with a standard adjustable drive are presented. It is shown that the use of this drive allows the level in the high-pressure heater to be efficiently controlled in different modes of operation with smaller consumption of energy for station ...

Low pressure chemical vapour deposition was used to deposit different silicon and silicon dioxide structures for thin film thermal heater by varying the working gas composition and substrate temperature. Silane gas diluted with argon was used to deposit silicon layers on different temperatures between 600 ^oC and 900 ^oC.
