EMISSION AND PERFORMANCE OF A LEAN-PREMIXED GAS FUEL INJECTION SYSTEM FOR AERODERIVATIVE GAS TURBINE ENGINES
ABSTRACT A dry-low-NOx, high-aimow-capacity fuel injection system for a leanpremixed combustor has been developed for a moderate pressure ratio (20:l) aeroderivative gas turbine engine. Engine requirements for cornbustor pressure drop, emissions, and operability have been met. Combustion performance was evaluated at high power conditions in a high-pressure, single-nozzle test facility which operates at full baseload conditions. Single digit NOx levels and high combustion efficiency were achieved A wide operability range with no signs of flashback, autoignition. or thermal problems was demonsuated. NOx sensitivities 10 pressure and residence time were found to be small at flame temperatures below 1850 K (2870 D. Above 1850 K some NOx sensitivity to pressure and residence Lime was observed and was associated with the increased role of the thermal NOx production mechanism at elevated flame temperatures

National Account Energy Alliance Final Report for the Ritz Carlton, San Francisco Combined Heat and Power Project
Under collaboration between DOE and the Gas Technology Institute (GTI), UTC Power partnered with Host Hotels and Resorts to install and operate a PureComfort 240M Cooling, Heating and Power (CHP) System at the Ritz-Carlton, San Francisco. This packaged CHP system integrated four microturbines, a double-effect absorption chiller, two fuel gas boosters, and the control hardware and software to ensure that the system operated predictably, reliably, and safely. The chiller, directly energized by the recycled hot exhaust from the microturbines, could be configured to provide either chilled or hot water. As installed, the system was capable of providing up to 227 kW of net electrical power and 142 RT of chilled water at a 59F ambient temperature
