Testing of a Pulsed L-Valve Feeder for Use in Fluidized-Bed Combustion and Sorbent Regeneration Units

摘要

A pulsed, L-valve solids feeder was tested at flow rates ranging from 2 to 50 kg/h. Particle size of the solids, pulse duration and pulsing-air flow rate were the main variables affecting the rate of solids flow through the feeder. Good reproducibility of flow rates was achieved. The potential of the feeder was also demonstrated using a rapid cycle time at the solids flow rates (up to 3.5 kg/h) required in ANL's fluidized-bed combustion and sorbent regeneration process development units.
