A DEVICE FOR REMOVAL AND DISPOSAL OF COARSE ASH FROM PRESSURIZED FLUIDIZED BED GASIFIER

摘要

The present invention relates to a Device for Removal and Disposal of Coarse Ash from Pressurized Fluidized Bed Gasifier and this arrangement is capable of removing and disposing the coarse ash from the pressurized fluidized bed gasifier, reducing the gasifier total structural height by eliminating ash receiver and ash hopper vessels and ash extraction at an elevated height from the distributor of gasifier, and also conserving energy by using the available pressure energy in the system for transporting coarse ash which otherwise is wasted by venting it to atmosphere or flare.
