Application of Vibrating Stop Plank in Soft Soil Improvement of Backfilled Foundation;

Directing against problems of large hot air leakage and high temperature inside the coal pulverizer after its shutdown,a retrofit scheme of additionally installing pneumatic slide plate gate into air-mixing duct at inlet of the coal pulverizer has been put forward,to use the pressure difference between hot and cold air at the inlet of coal pulverizer for sealing the hot air.

The gasholdup of gasliguidsolid three phase concurrent upflow in a reciprocating sieve plate column was investigated.
