Steam turbines have long been used at utilities and in industry to generate power. There are three basic types of steam turbines: condensing, letdown and extraction/condensing. • Letdown turbines reduce the pressure of ...

The recovery of waste heat energy is one element of a complete energy conservation plan. In addition to contributing to the goal of saving energy, utilization of waste heat is also an important source of cost savings. This ...

An extensive research project to derive guidelines for the design of a reliable bin-feeder system for biomass materials has been completed. The new system uses a converging mass flow hopper with a much smaller outlet ...

This paper outlines how to determine what transformer losses cost and how to evaluate transformer bids to optimize the investment.

Up until now, most of the literature on fuel cell cogeneration describes cogeneration at commercial sites. In this study, a PC25C phosphoric acid fuel cell cogeneration system was designed for an industrial facility and ...

In recent years, there has been renewed interest in energy efficiency in the semiconductor industry. The declining prices for semiconductor products has prompted semiconductor manufacturing plants to control costs so as ...

With today’s emphasis on efficient use and conservation of energy, selecting the correct pump for a given application requires not only a concise performance evaluation but also detailed economic analysis. A microcomputer ...

Not long ago, to evaluate the feasibility of a cogeneration project, a simple economic analysis, that considered capital required, operations and maintenance savings, was sufficient. However, under present economic ...

This report determines the conditions needed for an Organic Rankine Cycle to be economically attractive to recover heat going to air fins or cooling water. It includes discussion of some installations, and the impact ...

The variable energy characteristics of solid wastes, biomass and other low grade fuels, when utilized in cogeneration applications, introduce several additional plant design considerations. The effects of longer term ...
