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.
When talking about safety, you can't fully say a motorcycle rider is safer when compared to a car driver and the other way round. Both cars and motorcycle are motor-driven, and both of them are dangerous and risky you should definitely use properly. In other words, both cars and motorcycle are certainly not safe at all. But if we consider statistics, lots of road accidents are caused by motorcycles. Some of this accidents resulted to serious injuries and infrequently death. Since motorcycles are smaller than cars, they can move faster and may swerve in and out of lane which can be very dangerous. An irresponsible rider could find his demise when riding a motorcycle.
