Project Description
The Third Generation Of Two Stage Coal Gasifier
The Third Generation Of Two Stage Coal Gasifier
.Dry distillation section for refractory cross partition, wet ash discharge The advantages of this kind of furnace type: in the center of the dry distillation section to change the original stainless steel tube structure, replace stainless steel with refractory material, make a cross wall arch structure, retain the advant-ages of good effect of carbonization of dry distillation section, vent on the cross partition distribution, and to further improve, gas production can reach 6500-7000 m ³/h.Maintenance time from originalstainless steel tube structure of 1-2 years extended to5-8 years
