Rottary kiln methane consumption

Oct 30, 2017 2.3.1.3 Rotary Kiln Incinerators - Rotary kiln incinerators, like the other types, are designed with a primary chamber, where waste is heated and volatilized, and a secondary chamber, where combustion of the volatile fraction is completed. The primary chamber consists of a slightly inclined, rotating kiln in which waste materials
