The Role of Phosphate Brick in Lining of Fluidized Bed Gasifier

Aug 15,2017
Pressurized fluidized bed coal gasification technology in recent years with the rise of clean coal technology and the development of a new generation of large-scale, advanced coal gasification technology. High pressure, high temperature coal gasification reaction requires gasification reactor internal must be installed refractory lining, usually gasifier wall structure is divided into three layers: the innermost layer of refractory material, direct contact with high temperature reaction gas; the middle layer for the insulation Material; the outermost layer of stainless steel furnace wall. In addition to the key technologies such as reactor structure and ancillary equipment, the selection and baking of reactor lining materials are also the key technologies related to the success of the process due to the requirements of temperature, pressure and other reaction conditions. The life of the lining refractory is one of the main factors that affect the long-term stable operation of the gasifier.
