Webinar #2: Turbine Inlet Cooling Technologies and Applications for Optimizing Cogeneration/CHP Systems


Meeting Description:
Cogeneration and combined heat & power (CHP) systems can be the most efficient options for simultaneous production of electricity and thermal energy and are thus, good for minimizing fuel consumption and air emissions. Most large cogeneration/CHP systems use gas turbines. The capacities and other characteristics of all gas turbines are rated at the ambient air conditions of 59oF, 60% relative humidity at sea level. When the weather becomes hot, the demand for electric power increases, primarily because of the increased load of air conditioners. When the demand for electric power is high, the market price of electric energy for industrial, commercial and institutional also increases. Unfortunately, just when the electric power demand and electric energy prices are high, the electric power output of gas turbines could decrease by as much as 35 percent of the rated capacity. In addition, the energy efficiency of the gas turbine could also decrease by as much a 15 percent of the rated capacity.
 
Turbine inlet cooling (TIC) is used to minimize the detrimental impacts of hot weather on the performance of cogeneration/CHP systems that use gas turbines. Many TIC technologies are commercially available: wetted-media, fogging, chillers (mechanical and absorption), thermal energy storage and wet compression. This webinar will describe all of these technologies, their pros and cons, economics and applications for optimizing cogeneration systems.
 
WEBINAR SERIES: The Midwest Cogeneration Association (MCA) and the US DOE Midwest Clean Energy Application Center (RAC) are co-sponsoring a complimentary webinar series focused on bringing best practices and technical information to existing and potential users of CHP / Cogeneration systems that will assist users in determining and implementing effective efficiency and O&M strategies.
