After thermal upgrading, the coal is put through a deep bed stratifier cleaning process to separate the pyrite rich ash from the coal. When fed a typical low rank western coal, the SynCoal process can provide a product with a heating value of up to 12,000 BTU/lb with moisture and ash contents as low as 1% and %, respectively [ 100 ].

Abstract. The most commonly used wet ash handling system in which slurried ash is pumped to ash lagoons is compared with a relatively new dry ash handling system in which moistened fly ash and dewatered bottom ash are continuously transported to the disposal area and compacted. The proposed system for a typical 2,000 MW power plant features ...
