Coal based power makes up about almost 41 % with the world's electricity generation. Coal fired power plants operate on the modified Rankine thermodynamic cycle.The efficiency is dictated by the parameters with this thermodynamic cycle. The overall coal plant efficiency ranges from 32 % to 42 %. This is mainly dictated through the Superheat and Reheat steam temperatures and Superheat pressures. Most in the large power plants operate at steam pressures of 170 bar and 570 ??C Superheat, and 570 ?? C reheat temperatures. The efficiencies of such plants range between 35 % to 38 %. Super critical power plants operating at 220 bar and 600/600 ??C is capable of efficiencies of 42 %. Ultra super critical pressure power plants at 300 bar and 600/600 ??C is capable of doing efficiencies inside the selection of 45% to 48 % efficiency.
China's first production country, gradually developed into the world tire industry has been built all kinds of complete series of products of complete industrial system, and obtain a series of original innovation characteristics of international frontier technology progress. China's heavy-duty meridian has reached the advanced level of the world through high speed and high load test. The radial tyre of the sedan has achieved no inner tube, wide section, flat and high speed. The safety, energy conservation and environmental tyre of the international trend have been steadily pushed into the international market and gained recognition
