AbstractOne of the key requirements to efficiently and safely operate advanced power generation systems is to have knowledge of the process conditions. In addition to physical measurements (e.g., pressure, temperature), real-time knowledge of gas compositions at critical locations enables optimizing operational conditions. The goal of this project is to develop an integrated package to enable operation of MEMS sensors in the harsh environments associated with advanced power systems. This standard package will enable placement of a variety of chemical sensors in the process, and to quickly adjust for process variations (e.g. feedstock energy content, intake air humidity, etc.). In Phase I, Makel Engineering developed two integral probe designs for harsh environments, meeting the requirements for a wide range of applications within advanced power generation. The T-Style integral packaging was developed for installation in stationary turbines. The R- Style was developed for installation in refractory lined walls. Probes were fabricated and tested in simulated environments. Phase II will focus on testing chemical sensors in turbine and gasifier systems at a wide range of end user facilities that include DOE coal-fired facilities as well as facilities operated by Sacramento Municipal Utility District (SMUD) and turbine manufactures. This will demonstrate how advanced sensors can play an important role in characterizing the physical and chemical environments within gas turbines and other components present in emerging clean coal technology power systems. Advanced stationary gas turbines is the primary application for the technology, requiring. Measurement of species such as NOx, CO and O2 at elevated temperatures to optimize operational conditions. On a related application, temperature is the primary limiting factor in the placement of chemical sensor in aircraft engines.
