Double Stage Coal Gasifier

     The double  stage coal gasifier is also called the two-stage gasifier. It is named because the gasifier is composed of upper-stage gas and lower-stage gas. It is a system engineering, that is, the advantages of the two-stage furnace are inseparable from the various elements of the system, such as coal preparation, gasification, purification, pressurization, environmental protection control and public facilities. Its process flow is designed overall according to the different requirements and quality requirements of users for fuel.

     The two-stage coal gasifier equipment including carbonizing stage and gasifying stage, with 40-60mm bituminous coal for fuel. inthe upper stage, coal is carbonized. The carbonized coal becomes semi-cokes,then gets down to be gasified in lowerstage.Carbonization and gasification of coal are finished in same equipment. The carbonizing and gasifying gas, after optimized allocation,is disposed by dust-removing.tar-removing, cooling and sulfide-removing technology. The clean coal gas out of fumace is supplied to industrial kiln by gas pressure adding and transmission system. The whole system includes coal yard, slag yard, coal lifting system, light oil catcher and recycding system, phenol water disposal and incinerating system, autocontrol, coal gas storage, pressure adding and transmission system
