Identifying Savings Opportunities
MetadataShow full item record
In this paper, guidelines for identifying energy savings opportunities in industrial plants are discussed. The analytical approach used in this discussion stems from the fundamental principle that the total energy into and out of any process is constant. The starting point for identifying energy saving opportunities is to balance the equation INPUT = OUTPUT + LOSSES. Subsequent steps are devoted to identifying the causes for losses, and the means to reduce losses. The ultimate goal is to increase the ratio of output to input energy. Though the primary goal in this exercise is often energy conservation, there are many instances where substantial productivity gains result. Thus, the paper will also discuss other process benefits and possible disadvantages. The basic concept to remember in the whole exercise is that any energy using processes can be expressed in terms the following end-uses: • Motive Power Applications • Heat Transfer Applications • Electrolysis (Ion Exchange) Applications • Lighting Applications.
