Abstract	Microturbine generators (MTGs) offer an attractive alternative for addressing future demand for electrical power. However, increasingly stringent emission regulations such as those found in California pose a major technical challenge that these devices must overcome if they are to make significant market penetrations. In the context of these regulations, the present study characterizes the exhaust emissions and mixing capability of a commercial MTG and assesses (1) the ability of this device to meet future emissions regulatory requirement and (2) the extent to which mixing can be used to reduce emissions. The results establish that, for this MTG, both NOx and CO are minimized for 80–100% load. Kinetics and CFD analysis illustrate how NOx emissions are affected by local equivalence ratios and how fuel staging and local quenching impact CO emissions. Measured injector premixing levels indicate a standard deviation of less than 4% relative to the mean. Subsequent analysis using a well-stirred reactor approach suggests a maximum of a 10% reduction in NOx could be achieved with further improved premixing.
