Ash Handling. A huge quantity of ash is produced in the central station, sometimes as much as 10 to 20% of the total quantity of coal burnt in a day. Therefore hundreds of tonnes of ash may have to be handled every day in large power plants. Handling of ash includes: Its removal from the furnace.
The ash then settles to the bottom of the conveyor, and is efficiently conveyed to an inclined section of the system for dewatering, producing a manageable product. At the top of the incline, a discharge chute directs the ash into a storage bin or truck. The AllenShermanHoff SCC system is also ideal for handling mill rejects and economizer ash.
A dry bottom ashhandling system is probably more environmentally friendly and economic (from a capital cost as well as maintenance cost point of view). A short comparison of the dry system with the wet system is presented in Table II/
