Oxygen Transport Ceramic Membranes Quarterly Report

Description: In the present quarter, oxygen transport perovskite ceramic membranes are evaluated for strength and fracture in oxygen gradient conditions. Oxygen gradients are created in tubular membranes by insulating the inner surface from the reducing environment by platinum foils. Fracture in these test conditions is observed to have a gradient in trans and inter-granular fracture as opposed to pure trans-granular fracture observed in homogeneous conditions. Fracture gradients are reasoned to be due to o… more

COAL PARTICLE FLOW PATTERNS FOR O2 ENRICHED, LOW NOx BURNERS

Description: The year-end report summarizes the results of the series of experiments conducted to evaluate the effects of oxygen partial pressure on coal combustion. Specifically, the effects of oxygen partial pressure in the transport air stream on flame stability, flame standoff distance and overall NO{sub x} emissions were examined. A series of experiments were conducted to determine the effect of oxygen partial pressure in the transport air on flame stability and resultant NO{sub x} emissions. In summar… more
