Heat preservation repairing technique for the tank by the vacuum powder heat insulation method in the air separation device is presented, and related notable matters and key points are expounded.

Non-Uniform Mixing Cause Analysis of the Emulsion in the Storage Tanks for VAE Products and Improvements;

The Discussion About The Failure Under External Pressure Of Inner Press Vessel In Cryogenic Vacuum Storage Tank With Powder Insulation;

Those problems include:(1) how to determine the value for the temperature differences between inside and outside surfaces of the wall,and the wall pressure from the coal storage;(2) the distribution of the resultant in the wall resulting from the temperature and the wall pressure;(3) the resultant in the piles caused by the coal stacking.

How to improve the utilization of space,reduce area and the amount of soil,saving the investment of equipment,reasonable and necessary optimization for coal storage system in engineering design,without reducing the reliability of coal handling system and the security of coal supply,is a practical problem to the design of coal storage field in modern power plant of domestic.
