Protective systems for high temperature applications (EFC 57) PDF

The Kyoto Protocol, which came into force in 2005, aims to reduce worldwide emissions of greenhouse gases (GHG). Fossil fuel fi red power plants are among the largest and most concentrated producers of CO2 emissions. Additionally, a rapidly growing demand for electricity is projected over the next 30 years [1], especially in highly populated and fast-growing countries such as China and India.

The main strategies to reduce CO2 emissions in the power sector are increased effi ciency, and carbon capture and sequestration (CCS). Increased effi ciency corresponds to producing more energy for the same amount of fuel, hence effectively reducing CO2 emissions. This can be achieved by worldwide implementation of stateof-the-art power plant technology for new installations and the replacement of old inefficient power plants. The efficiency of conventional power plants can still be increased by further development of the technology, e.g. 700 °C steam power plant.

The long-term strategy for the reduction of CO2 emissions is the recovery and sequestration of CO2 produced during power production. To achieve this goal, several new power plant concepts have been developed in recent years, which are currently under investigation from both engineering and economic points of view.
