Accurate
knowledge of temperature is a critical factor in the fine tuning of coal
gasifiers and systems using integrated gasification combined cycle (IGCC) power
generation. At present, there are no
robust techniques available that can withstand the harsh operating conditions of
the gasifier. This project will
develop novel fiberoptic temperature measurement devices and systems based on
high-temperature refractory materials, which have been demonstrated to withstand
the environment of an IGCC system. In
Phase II, these devices will be developed into complete systems and integrated
into a suitable testbed reflective of IGCC conditions.
Phase I will consist of materials research, testing, and optical device
design appropriate to gasifier measurement.
The materials that are best suited to the IGCC environment will be
determined along with procedures for device preparation and for optically
interrogating the devices to determine temperature.
Commercial
Applications and Other Benefits
as described by the awardee: The
temperature measurement system should offer greater performance, reliability,
robustness, compatibility with gasification systems, integration with existing
and evolving control systems, ease of use and on-line replacement. Applications include not only the power generation industry but also
materials processing and military applications.
