O-25. Case study—Executing a 210 kW combined heat and power project

Presenter: Mark A. Linsberg, Enerfab, Cincinnati, OH

Combined heat and power (CHP) is an efficient and clean approach to generating electricity and useful thermal energy from a single source of fuel. CHP has been in use in the Unites States for more than 100 years and currently represents approximately 8% of all generating capacity or 82,000 MW, located at over 3,600 industrial and commercial facilities. Centralized electric power generation in the United States typically converts 34–35% of the fuel consumed into electricity, with the remainder of the energy lost in the form of waste heat. Installing a CHP system that uses thermal energy and electricity can result in 60–85% of the fuel energy being utilized. Breweries are great potential candidates for implementing CHP because electricity, steam, and hot water are all requirements of the brewing and packaging processes. Although there are several U.S. breweries that have installed CHP systems, the majority have not. We believe there is great opportunity for additional U.S. breweries to cost effectively implement CHP projects. Successful execution of a CHP project requires financial, legal, engineering, construction, and environmental expertise. The case study presented describes the process of developing a 210 kW CHP project from concept though start-up. The steps described in the study are applicable to most CHP projects no matter the size.
