Abstract: Diesel generators that operate at partial power can experience wet stacking, low efficiency, and poor exhaust emissions. These problems create excessive maintenance, reduced lifetime, high fuel consumption, and poor air quality. Although exhaust treatment systems can improve air quality, most technologies are impeded and/or damaged by high sulfur fuels used in some areas. The costs associated with these deficiencies are significant. As a result, we propose to develop simple, cost-effective techniques to address these shortfalls. Specifically, we plan to modify existing generator designs to include turbochargers and Electrically Buffered Control Systems (EBCSs). This work will leverage Creare's extensive experience with turbomachines and thermodynamic systems, and their electronic controls. Our approach utilizes a large number of commercially-available components to minimize cost. We expect savings from reduced maintenance and fuel consumption to exceed the cost of implementing our technology. During Phase I, we will optimize our approach for a specific military generator, quantify its impacts, and estimate implementation costs. We will retrofit several generators with our design features during Phase II and conduct laboratory and field tests.
Benefits: Our proposed approach will provide a reliable, cost-effective method to eliminate wet-stacking, increase fuel efficiency, reduce exhaust emissions, and improve power quality. The solution is scalable and adaptable for all generator sizes, and it is not impaired and/or damaged by high sulfur fuels. Our features can be incorporated easily into military and civilian generator designs, and existing systems can be retrofit to include them.
