摘要:

The advent of double effect absorption chillers has created new opportunities for gas cooling in regions where gas prices are relatively low compared to electric prices; however, consideration of fuel price, efficiency, maintenance, and first-cost may encumber the opportunity with only slight fluctuation.

摘要:

Utility deregulation and competition are advancing to a point where energy managers need to prepare themselves to take advantage of the changes to come. Many steps can be taken now—before the rules change—to maximize those benefits. Some of those efforts may even yield savings before deregulation occurs. They include: collecting and managing load information, experimenting with time-sensitive tariffs, analyzing and/or re-designing present loads, organizing other end users, negotiating with your utility, and issuing RFPs for market-based power.

摘要:

Energy usage has been the target of various conservation and cost control strategies for many years. Technologies have ranged from turning equipment off, to mystical black boxes that lower costs. Utilities have been instrumental in the support of customer energy conservation and development and implementation of efficiency improvements. Natural gas fuel cells are a direct energy conversion technology that has reached stages of development that will begin to supply electrical energy (and associated thermal energy) at comparable life cycle cost to those available from more conventional combustion based electrical generation systems. This article will briefly describe the basics of fuel cells and types of fuel cells. Recent advances in fuel cell technology and installations will be discussed. Finally an analysis will be presented to determine their future within grid, industrial, commercial, and/or residential applications.

摘要:

Asimulation model for evaluating use of spare batteries for forklift trucks is developed. User-provided inputs to the model include number and sizes of forklift trucks and batteries, probability function for usage, and interchangeability of forklift trucks. The simulation output can be used for estimating costs and payback period for purchase of spare batteries.

摘要:

U.S. manufacturing must extract the highest percentage of productive energy from each Btu of energy produced, especially since it has a high per capita consumption of energy in the industrial sector. This is necessary for competing in the “global” marketplace. This article describes the design and development of a computer based tool (ENERGEX) which aids the industrial user in developing energy conservation opportunities (ECOs) in plants. The software system is capable of recommending ECOs in areas such as lighting, boilers, motor selection, analysis of belt driven systems, destratification, insulation of heated surfaces, and air compressor operation. In addition, the system offers expert advice on all these areas including power factor improvement possibilities. The system has been designed so as to query the industrial user on aspects related to the plant, from which the most appropriate ECO list is generated and presented for further analysis.
