Coal Feed System for Atmospheric Fluidized Bed Combustion Boiler

Abstract

Atmospheric fluidized bed combustion (AFBC) boiler is one of the important break-through in the area of coal combustion technology, Recently a number of demonstration plants of AFBC boiler have been constcted by utility companies in the world.
The coal feed system of AFBC boilers plays an important role for successful operation of AFBC boilers. Employing the unerbed feed system, we have developed a feed system for AFBC boilers and carried out experimental study using a pilot plant. The developed feed system achieved stable transportation of dense coal-air mixture and uniform distribution with the multi-outlet distributor.
