In an overall sense, FBC acid gas emissions are dramatically lower than those from other combustion system such as chain grate stoker, underfeed stoker, pulverized coal spreader etc.,(without external flue gas treatment).
Sa kabuuan, ang emisyon ng asidong gas ng FBC ay mas mababa kumpara sa ibangg sistema ng kombustyon gaya ng “stoker” na may kadenang pangkayod, “underfeed stoker,” taga-kalat ng dinurog na coal, etc (hindi gumagamit ng panlunas sa gas na “external flue”).
