Isokinetic sampling of reduction gas - using sampling pipe applied during coal pressure gasification from channel flow of pipe line

摘要

Isokinetic sampling of reduction gas during coal pressure gasification from channel flow of pipe line has sampling pipe which is inserted in opening of pipe line. The gas-tight sampling pipe is taken out through one end of the housing of a cut-off device. The housing is mounted on a short connection of the pipe line. The sampling pipe is provided with a threaded spindle, a hand wheel and an axial groove which secures it against distortion. The axial groove interacts with a guide in a bushing where the sampling pipe is seated. The channel float is formed in a pipe.
