Abstract：
 A high-temp solid material feeding-back value for the circulating fluidized-bed boiler is composed of descending tube, horizontal tube, ascending tube, feeding-back zone and aerating unit, and features that the geometric parameters of all parts are optimized, and the work state of whole valve is the aerating flow. Said aerating unit is positioned only in said horizontal tube. Its advantages are simple structure, high reliability, low pressure requirement, no coking problem and high regulation effect.
