  • This paper describes basic characteristics of major production units from a pulp and paper manufacturing plant, focusing on major aspects of risk exposure experienced during construction and operation. Different types of pulp and paper manufacturing processes are presented with particular consideration of risks pertaining to the production stage and pertaining to new technology. Turbines and gas turbines are not handled in this paper due to the fact that these have been presented in earlier IMIA papers. The last chapter is dedicated to some interesting cases of loss.

  • In 1993, the U.S. Department of Energy (DOE) Office of Industrial Technology (OIT) established a group of seven industries designated as Industries of the Future (IOF). These industries were selected for their high energy use and large waste generation. The original IOF included the aluminum, chemicals, forest products, glass, metalcasting, petroleum refining, and steel industries. Each industry was asked to provide a future vision and a road map detailing the research required to realize its vision.

  • This book is concerned with the subject of Wind Energy, as a source of clean and renewable and free for all. The need for this type of book is very well documented, the current consumption of energy is unsustainable and humans have to change their habits and or utilise this source, but there is so much work before we can rely completely on renewable energy. This book aims to describe the fundamentals of wind energy and the pertinent parameters that control the amount of energy available from a given wind turbine. Coal fuelled the industrial revolution in the 18th and 19th century.

  • Today’s wind energy industry is at a crossroads. Global economic instability has threatened or eliminated many financial incentives that have been important to the development of specific markets. Such economic sponsorship of energy generation is not unique to renewables; fossil based sources are also subsidized in many different countries. However, for a technology like wind energy whose markets are still developing, incentives can be critical for industry growth.

  • The confluence of market demand for greatly improved compact power sources for portable electronics with the rapidly expanding capability of micromachining technology has made feasible the development of gas turbines in the millimeter-size range. With airfoil spans measured in 100’s of microns rather than meters, these “microengines” have about 1 millionth the air flow of large gas turbines and thus should produce about 1 millionth the power, 10-100 W.

  • A second source for private sector expenditure on R&D is the “EU Industrial R&D Investment Scoreboard”, which has been conducted by the Institute for Prospective Technological Studies (IPTS) that is part of the Joint Research Centre of the European Commission. The annual Scoreboard presents information on the world’s top 1400 companies ranked by their investments in R&D. It contains data drawn from companies’ accounts, most recently for the fiscal year 2009. 16 R&D indicators, such as R&D intensity, vary in line with the business cycle.

  • In an effort to assess the impact of recent trends that may have affected industry energy consumption since the CEF report was produced, we also examined reference case energy consumption projections for the pulp and paper industry produced in connection with EIA’s Annual Energy Outlook 2006 (AEO 2006), which also uses the NEMS model but incorporates more recent energy and economic data. However, AEO 2006 also projects production to grow (increasing at 1.

  • When unfired units are designed with higher steam conditions for combined cycle, multiple-pressure units are usually applied to increase exhaust heat recovery and enhance system performanc The intermediate level may be that required for steam injection fo NOx control and/or a process level. In applications using natural gas, a third pressure level will further enhance overall system performance. Typical design practice is that unfired HRSGs are convective heat exchangers that respond to the exhaust conditions of the gas turbine.

  • The late 1940s through the 1950s saw rapid technological advancement and the introduction of rotating equipment. Larger and higher horsepower equipment came into use. This brought about the need for more “power-dense” flexible couplings with greater misalignment, which had to be accommodated. Around this time the fully crowned gear spindle (Figure 1 S A ) was developed and introduced into the steel industry. Also during this period, the use of the gas turbine in industrial applications (generators, compressors) was becoming popular.
