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.
However, science and technology are two different social cultures, and the differences between them are obvious. The basic task of science is to know the world and find it, thus increasing the intellectual wealth of mankind. The basic task of technology is to discover the world and invent it to create the material wealth of mankind and enrich the spiritual and cultural life of human society. Science answers questions about "what" and "why"; The technology answers the question "what to do" and "how to do". Therefore, the results of science and technology are different in form. Scientific achievements are generally expressed as concepts, laws, papers and other forms. The technical results are usually in the form of process flow, design drawing, operation method and so on. Scientific products are generally not commercial and technological achievements can be commoditized. Modern technology has a strong utilitarian and commercial color.
