The ANL High Temperature/Pressure Samplers Program develops, under guidance of the Morgantown Energy Technology Center (METC), samplers for installation at selected locations in coal-process PDU, pilot, and eventually, demonstration plants, to improve monitoring of plant performance. Two samplers have already been designed and procured, a Non-insertable, Isothermal Gas Sampler and an Insertable Pyrometer. The former component is designed to collect gas samples near the wall of a water-cooled coal process vessel, such as the METC low-Btu gasifier, and deliver the gas isothermally to an analyzer. The sampler line heaters and their control console, which controls the heaters at the gas sample stream inlet temperature, have already been tested at 1500/sup 0/F. Also, the pressure letdown system, which provides for a 300 psi drop from gasifier to analyzer, has been calibrated for use as a flowmeter. The Insertable Pyrometer is designed to penetrate into the interior of a pressurized coal-process vessel, such as the METC gasifier, and measure radial temperature distributions, to at least 2000/sup 0/F. The reference probe houses a quartz rod that transmits infrared signals from the vessel interior to a signal analyzer outside the vessel. The entire component has already operated satisfactorily away-from-vessel. In addition, an Insertable, Combined, High-Velocity Thermocouple and Isothermal Gas Sampler, that combines many features of the first two components, has been designed and is under procurement. Finally, the conceptual design of a Coring-Type Solids Sampler has been completed.
