A non mechanical, pneumatic feeding scheme for small scale combustion or gasification facilities fueled with rice hull is presented. The scheme was designed based on a modified traditional configuration of L valve feeding system specially for rice hull feeding. The delivery capacity, adjustable range and transportation efficiency of the feeder were experimentally studied. It proved that this developed feeder has large adjustment range with low gas solid ratio and can work well under low load. Compared with other mechanical feeding schemes, it's simple, reliable and low cost and can be used in various situations.
