Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To effectively utilize biomass waste in a short processing time while suppressing apparatus cost and operating cost to a low level.SOLUTION: Biomass waste W is mixed with at least one of a calcined cement raw material, dust D obtained by dust collection of combustion gas extracted from a kiln exhaust gas flow path ranging from the kiln tail of a cement kiln to a lowermost cyclone, and quicklime, and the resulting mixture is used as fuel or/and raw material for cement production. In the mixture M, a low specific gravity powder component L can be used as fuel for cement production and a high specific gravity powder component H as raw material for cement production. Waste plastic is removed from the mixture and the removed plastic can be blown from a cement kiln burner after crushing to 5-50 mm. The biomass waste may include garbage or/and excrement discharged from ordinary homes.
