文摘

The hollow-bottom and wall-style gasifier and pinnate-pattern boreholes have been used. Two injection points were used for controlling the moving of flame work face. Multicomponent oxygen-rich was used to produce high calorific value gas. The combustion situation with an “S” form or arch shape was detected by micro-seismic detection system.
