In wet agglomeration, a liquid binder is added to two or more dry ingredients to cement the particles together, thus forming larger particles. Several types of liquid-solids blenders can be used for wet agglomeration. This article's first section discusses the basics of wet agglomeration.
Waste-derived fuels, such as solid recovered fuel (SRF), are increasingly being used in, e.g., the cement industry as a means to reduce cost. The inhomogeneous nature of SRF makes it difficult to combust, and many problems may arise within, e.g., combustion control, feeding of fuel, deposit formation, or accumulation of impurities. The combustion of polyethylene (PE), polypropylene (PP ...
