Currently, over 80% of our country's electricity supply still comes from fossil-fueled power plants. Although many aging units have been gradually decommissioned and updated in recent years, there are still many units in the mid-term of their lifespan. Therefore, maintaining or improving the efficiencies of existing fossil-fueled power units are crucial for current carbon reduction efforts.
NARI has developed the thermal performance analysis technology. The customized performance analysis models of key equipment/components (ex. steam turbine, feedwater heater, condenser) and system (steam turbine cycle) are constructed, and the utility’s operation data, design data, maintenance data, fuel prices, equipment upgrade prices, and other information are utilized to assess the efficiency loss and increased carbon emissions caused by equipment aging or deviation of the operating conditions. The analysis results provide valuable information which can help the decision making of the investment of the equipment and find out the potential operational issues. This aids in enhancing the power generation efficiency of fossil-fueled power plants and reducing their CO2 emissions.
