| Abstract;After the industrial revolution, the concentration of carbon dioxide (CO2) in atmosphere has risen steadily, but it has risen rapidly after the World War 2, and today it reaches above 370ppm, the highest level in more than 650,000 years. The global temperature has raised parallel to this CO2 concentration in the atmosphere. The main reason for this sharp rise in global temperatures since the 1850s is thought to be a steep increase in atmospheric CO2 from human use of fossil fuels. Strong government action is needed to combat this most urgent environmental problem, and primary energy consumption per GDP as target in 2008-2012 is definite promised for the countries pledged at the Kyoto Conference on World Climate Changes, or COP-3. The pledge was: amount of greenhouse gases to be released in the year 2008-2012 will be 6% for Japan, 7% for United States of America and 8% for European Union, less than the level released in 1990. We must works for environmental problems to realize the pledge of COP-3 without lowering its economic capabilities by reducing the emission of greenhouse gases. Large, LNG burning gas-steam combined cycle power plant whose thermal efficiency is about 30% higher than that of coal or oil burning thermal power plants, will be introduced in the stand point of view of high temperature technologies. To improve the efficiency of thermal equipment that consumes large amounts of electric energy is also very important. The high efficient turbo chiller whose COP (Coefficient of Performance) is 6.4 is attained by improving radial compressor aerodynamic performance, improving heat exchanger performance and adopting inverter controlled electric motor is introduced as a typical example of high efficient thermal equipment. In this paper, the contribution of the progress of energy and thermal power plants will be described. (author abst.) |
