Environmental Protection of the project the main raw material for coke production and transportation process production division under objects, particles less than 5mm powder state the coke powder or weakly caking coal powder. The raw material is difficult to use, and direct fuel to give environment resulting in greater pollution, coke, coke powder or pulverized coal molding can substitute coke for the iron and steel smelting and casting industry. The project uses state-of-the-art closed kneading technology, equipment and production process is basically no "three wastes" production and rational use of surplus gas, heat generated in the production of formed coke. Added to the manufacturing process of the type coke Run-sheng adhesive strength can change the type of focus, so that the temperature does not Ye crack, played solid sulfur to reduce toxic gas emissions, improve fuel value of the type coke.
