| Abstract: | The parameters as well as the operation philosophy of the vertical pipe of the Texaco coal gasifier were discussed. By using the CFD software, the cold-state simulation of the gas flow distribution of the vertical pipe under nor- mal operation conditions was performed, and performed also was the simulation under such abnormal conditions as partial plugging, symmetrical plugging, non-symmetrical plugging at the slag discharge end. The result showed that plugging at the slag discharge end causes bias gas flow in the vertical pipe. |
