Electricity generation based on fossil fuels is taking a Iead position in the world. According to prognosis by the World Energy Council (WEC) fossil fuels, with a share of 77 % in 1997, will also contribute with 65 to 75 % to the power generation in the year 2020. With a current share of 40 % coal is the most important energy source worldwide.

Environmental aspects as well as the efficient application of fossil fired power plants in die liberated European energy market require further development and improvement of existing plant technology. During the past years intensified investigations were carried out to raise the efficiency of fossil fired power plants. The results show the potential that in some cases the efficiency could be raised by several percentage points.

Within the scope of the VGB Research Project KOMET 650 investigations were carried out to increase the efficiency of fossil fired power plants through elevated temperatures and pressures of the steam process.
