Flexibility — Microturbines may be a more viable option at smaller and older landfills where landfill gas quality and quantity would not support more traditional landfill gas electric power generation technologies. They may also be feasible at larger landfill gas projects that have excess unutilized gas,. Compact and Fewer Aloving Parts — Microturbines are approximately the size of a large refrigerator and require minimal operation and maintenance. The use of air bearings coupled with an air - cooled generator eliminates the need for lubrication and liquid cooling systems. Lower Pollutant Emissions — Microturbines burn cleaner than comparable r'ecipr'ocating engines For example, NOx emissions levels from microturbines are typically less than one -tenth those of the best performing reciprocating engines and lower than those from a landfill gas flare Capable of Conrbrr.sting Lower- Methane - Content Landfill Gas — Microturbines can operate on landfill gas with .35 percent methane content and perhaps as low as 30 percent. • Ability to Generate Heat and Hot Water — Most microturbine manufacturers offer a hot water generator as a standard option to produce hot water (up to 200 °F) from waste heat in the exhaust. This option can replace relatively expensive fuel, such as propane, needed to heat water in colder climates to meet space - heating requirements. The sale or use of tnicroturbine waste heat can significantly enhance project economics. Orange County 9 March 2006 Draft
