Tens of thousands of gas turbine engines are used in the utility electric power market (utility companies) and the nonutility electric power market (industries of aluminum, chemicals, steel, wood and paper, agriculture, and others). Thousands of new gas turbine engines are to be installed to accommodate the worldwide increase in power needs during the next few years. Numerous pollutants are released into the atmosphere each year in the exhaust of these engines. This Phase I project will demonstrate the feasibility of an innovative emissions/performance and health monitor for improved tuning control of gas turbine engines. The in situ exhaust sensor will: (1) speciate and quantitate gas phase chemical species, (2) measure gas phase temperatures, and (3) monitor particulate loading and composition. The sensor will provide real-time information for facilitated tuning of engines as it monitors for environmental emissions levels, engine performance, and rapid malfunction detection in advance of catastrophic engine failures. The engine tuning control afforded by the sensor will reduce pollutants released into the atmosphere by tens of thousands of tons per year. A field test of the Phase I prototype is planned at an engine test cell of a major engine manufacturer.

Phases I and II of this project will result in an on-engine product that will benefit the environment as well as turbine engine manufacturers and engine end-users. Improved engine emissions/performance and health monitors are desired by the manufacturers of advanced turbine engines to facilitate test programs and bring engines to production sooner. Engine end-users also desire such monitors to indicate optimum performance as well as provide early warning of catastrophic engine failure. Significant savings are realized in fuel consumption, engine replacement parts, power generation downtime, and labor costs associated with repairs. Engine manufacturers project upwards of 500 advanced stationary turbine engine installations will be realized annually beginning in the year 2001 (end of Phase II of this project), and as stated above, tens of thousands of traditional gas turbine engines are already in service.
