Industrial Waste Heat Recovery and the Potential for Emissions Reduction. Volume 1. Main Report

摘要

This report examines the applicability of conservation equipment to various industrial sectors, determines the net costs involved, and assesses the potential for conservation as a means of air pollution control. Predictions of the amount of waste heat available from U.S. industrial sources were made and a waste heat inventory was established. The inventory is segmented by industrial group, industry, process, and flue gas temperature. The waste heat recovery equipment analysis determined the costs and applications of a variety of waste heat recovery equipment. The analysis examined five major equipment types and their limitations. Cost functions were developed which used furnace flue gas flow rate and temperature, and air preheat temperature as inputs. A discussion of the major factors to be considered for the development of heat recovery equipment also is included. A discussion on the availability and development of high temperature burners and the effects of high preheat temperature on ancillary equipment is included. High preheat temperatures result in higher flame temperatures and correspondingly higher NOx emissions. This issue also has been addressed in this report. Volume 1 describes study methodology and findings. Volumes 2 through 10 tabulate stack gas waste heat inventories for all the industrial processes studied.
