What is the thermal efficiency of a coal-fired power plant (CFPP)?
The cycle thermal efficiency of 44.41% and exergy efficiency of 39.85% for this coupled system are higher than those of a conventional coal-fired power plant (CFPP), enhancing the unit's thermal performance and flexibility.
Can thermal energy storage enlarge the load-cycling range of coal-fired power plants?
The operational flexibility of coal-fired power plants (CFPPs) should be effectively enhanced to accommodate large-scale photovoltaic and wind power within the power grid. The integration of thermal energy storage (TES) systems is a potential way to enlarge the load-cycling range of CFPPs.
How to improve peaking performance of coal-fired power plant?
Energy, exergy and economic analyses are deeply evaluated. The peak range of CFPP is from 18.39 % THA to 106.35 % THA. In order to improve the peaking performance of the coal-fired power plant (CFPP), this paper proposes a scheme, which integrates a CFPP with the high-temperature and low-temperature molten salt thermal storage.
How do you evaluate a coal-fired power plant project?
The process included evaluation of the following criteria for each coal-fired power plant project: Examination of the proposed coal-fired power plant construction program. For a plant to be designed to be ‘capture-ready’, the decision must be made at plant site selection stage.
Are coal-fired plants 'capture-ready' in developing APEC economies?
The primary objective of the project is to develop guidelines for planning and cost assessment in relation to making future coal-fired plants in developing APEC economies ‘capture-ready’ as an aid to capacity building on carbon capture and storage in these economies. 2. Carbon Dioxide Capture and Storage
Can molten salt thermal storage improve peaking performance of coal-fired power plant?
It can be seen that the multiparameter molten salt thermal storage can effectively improve the peaking performance of the coal-fired power plant. Based on the results of the exergy analysis, the exergy efficiency of the integrated system is 37.43 %, which is a decrease of 1.58 % compared to the 39.01 % of the reference coal-fired power plant.
