摘要:

Compressed air is often the most expensive utility in an industrial facility, and cost-effective efficiency opportunities in both the production and use of compressed air are often ignored by facility operators. Leaks, inappropriate uses of compressed air, poor choice of compressors and ancillary equipment, pressure problems and poor attempts to solve them, and inefficient controls are among the many contributors to compressed air inefficiency in many industrial facilities.

摘要:

A long with the shortage of conventional energy sources, efforts have been sought to use energy in a rational manner. Whereas the biggest energy consumption is in the industrial sector, various techniques to reduce energy have been searched. For industries, this will result in the reduction of production cost. In industry where steam is utilized, the steam production and distribution system consumes a significant portion of energy. Therefore, optimization of steam systems is among the biggest energy saving potential in industry. The optimization measures can be categorized into two methods, i.e. (1) no cost/low cost that can be done through better maintenance and improvement of operating conditions, and (2) major improvement that requires a significant amount of investment, that includes the modification of process and major equipment. Since energy saving is an endless effort, new levels of energy efficiency standards are being set year after year. Therefore, repeated studies should be made to identify energy saving potential. Modern instruments allow the energy specialists to conduct an in-depth survey to identify energy performance.

摘要:

One of the most perplexing problems for industrial power plants committed to improving competitiveness is measuring variable cost performance over time. Because variable costs like fuel and electricity represent the overwhelming majority of power plant expenses, it is imperative to develop and deploy a tool that can help plants benchmark operating performance.

摘要:

This article presents a summary of the practical lessons learned to date from the U.S. Department of Energy's (DOE) Showcase Demonstration Projects. These projects are part of the DOE MotorChallenge Program, and are aimed at demonstrating increased electric motor system efficiency through the integration of a variety of technology and applications options. These include: energy efficient electric motors, adjustable speed drives, and motor-driven equipment (e.g., pumps, fans, and compressors) within industrial operations and processes. Each showcase project is made up of a team that consists of a host demonstration site and supporting partners (e.g. utilities, motor and process equipment suppliers, and contractors). Each team is expected to provide DOE with sufficient data to substantiate and document the energy and environmental performance of the project and the economic cost/benefit of the results. Additionally, teams provide appropriate information to DOE to allow DOE contractors to perform an independent performance validation report and to prepare a comprehensive case study document. DOE provides each showcase team access to technical experts who will assist on questions which may arise during the course of the project. DOE also sponsors workshops to allow Showcase teams to exchange information and discuss lessons learned. At the conclusion of each project DOE publishes and distributes a comprehensive case study document.

摘要:

Most plant steam systems are complex systems. Usually the fuel required to produce the steam represents a major expense for manufacturing facilities. By properly operating and maintaining the steam system and making minor improvements, significant savings can be realized.

摘要:

In reviewing hundreds of process improvement projects, the author has found that virtually all fall into at least one of six categories. By looking for places where one or more of these characteristics occur in existing (or proposed) processes, one can identify opportunities for projects that reduce energy consumption, decrease waste, improve yields, and in other ways cut costs.
