Best Practices - Combined Heat and Power
The principle of Combined Heat and Power (CHP) goes by a number of acronyms, each capturing a slight variation on the basic concept. In CHP systems, waste heat from power generation equipment is recovered for operating equipment for cooling, heating, or controlling humidity in buildings, plant facilities or for process applications.
The presentation and workshop materials developed as part of the Illinois IOF program compliment ongoing efforts at the Energy Resources Center through the Midwest CHP Application Center. This U.S. DOE sponsored activity is a partnership between UIC/ERC and the Gas Technology Institute (GTI), providing application assistance, technology information, and educational support in the eight Midwest states of Illinois, Indiana, Iowa, Michigan, Minnesota, Missouri, Ohio, and Wisconsin. The Midwest Application Center is primarily focused on commercial building and institutional applications, so the Illinois IOF program adapted this information for the industrial market.
In today’s economy, uncertain energy prices for both electricity and natural gas confuse the economics of traditional CHP applications. However, industrial facilities should always investigate the potential of recycled energy. Recycled energy uses the energy content of flared gases, wasted exhaust heat or unused gas pressure drop to generate electricity. Used extensively in the steel industry, this concept is increasing popular with chemical companies and other locations with high temperature waste streams or exothermic reactions.
CHP is widely applied in the industrial, commercial and industrial markets. One notable installation is at the University of Illinois at Chicago’s East Campus. This application is featured by the U.S. Department of Energy’s Distributed Energy Program website along with several other case studies and technical resources.
