It includes twenty-eight excellent studies prepared using state-of-art methodologies by professional researchers from different countries. The sections in the book comprise of the following titles: power transmission system, manufacturing processes and system analysis, thermo-fluid systems, simulations and computer applications, and new approaches in mechanical engineering education and organization systems | Part 3 Thermo-Fluid Systems 16 Waste Heat Recycling for Fuel Reforming Rong-Fang Horng1 and Ming-Pin Lai2 Department of Mechanical Engineering Kun Shan University Tainan City 2Department of Aeronautics and Astronautics National Cheng Kung University Tainan City Taiwan 1. Introduction At the current rate of consumption it is estimated that the crude oil reserves of the entire world will be depleted in less than 40 years. Due to an unstable international situation the price of crude oil keeps rising compelling the price of other fossil energies to soar. Because of its high dependency on imported energy Taiwan is deeply affected by the crude oil price. Additionally because of its low cost and high carbon number fossil fuel has been the major fuel used in Taiwan. The enormous number of vehicles and motorcycles in Taiwan emit excess amounts of carbon dioxide sulfur and nitrogen consequently the level of greenhouse gas emissions in Taiwan far exceeds that of other countries. Because coal natural gas and petroleum will still be the major sources of energy in the short to medium term future and since increasing energy efficiency is presently a globally acknowledged strategy the use of new energy technologies for the transformation of traditional fuels into clean fuels - such as clean coal fuel cells and fuel reforming - is being promoted all over the world. Combining all the factors described it has become necessary to quickly develop new energy and combustion techniques with existing equipment and resources to reduce air pollution produced by combustion. Plasma-assisted reforming of hydrogen production is a promising energy utilization technology and an increasing number of research units are conducting related experiments around the world. Plasma-assisted production of hydrogen is different from traditional hydrogen production approaches and the equipment involved in the plasma-assisted production of hydrogen is small easy to start and economical it can also increase .
