和文要約
英文要約Trypilska Unit-4 in Ukraine is a coal-fired unit of 300MW and started commercial operation at 1972. Although Trypilska Thermal Power Plant had got their maintenance work periodically and has been operated stably for around 40 years, the unit efficiency is not high because the unit itself is with outdated design. Therefore, the efficiency enhancement for the existing steam turbine was proposed by replacement of HP, IP and LP section using the latest steam path technologies.
The high efficiency and reliability derived from the latest technologies have sufficient sustainability and provide the heat rate enhancement on the same rated output with the reduction of Carbon Dioxide Emission as well as fuel consumption. And also, in the achievement, it is underlined that the required scope in this proposal is more economical than the construction of new plant, because the modification and/or design change for Boiler, Generator, Main Transformers, BOP (Balance of Plant) and so on are not requested in case their operating condition is sound.
In the project, the additional scope is included due to request by Ukraine side, such as overhaul for the reused components of the existing steam turbine, replacement of governing system with electrical hydraulic control, installation of new monitoring system for turbine vibration & operating parameters, replacement of boiler feed water control valves & spray water control valves, modernization for unit monitoring & control system and so on. They can contribute for improvement on the unit reliability & operational-ability.
This feasibility study is for the demonstration on the heat rate enhancement of this unit and the dissemination on the around 20 units of similar 300MW which are now operating in the similar condition in Ukraine and CIS countries.
