Abstract：Following the explanation on so called dead space in gasification system of fixed bed gasifier which have a great deal of negative influences on gasification, causing underutilization of added nitrogen-rich air in the phase of gas generating, higher content of carbon dioxide in the gas, more steam losses in up-and-down blowing phases and incomplete recovery of useful gas in the air-blow phase etc., the author presents some countermeasures based on analyzing in detail combined with practices in Hunan Zhicheng Chemical Co., Ltd.
