The bottom ash disposal device and its corresponding hydraulic ash handling system
mechanical wet ash handling system and mechanical dry ash handling system were introduced. The characteristics and development prospects of each system were compared. Taking a 2 ×660 MW project as an example
the technical and economic comparison between the air-cooling dry-type proposal and submerged scraper chain proposal were caaried out
The results showed that under the condition of same initial investment
dry type proposal had lower operating costs
less water conservation
higher energy efficiency
better utilization of ash and the obvious advantages. Therefore
