The solution of problems such as water hammer,hard to dispose the noncondensables,air lock and selection of steam trap were discussed to save energy,protect environment and lower the cost.

There were some problems existing in steam condensation water recovery system,such as equipment was expensive and low recovery rate,waste heat resource can t be recovered effectively,the reasonable allocation in trap and uncoagulate gas.

Influence of noncondensable gas in the gas space on natural circulation flow boiling;

Results show that severe accumulations of noncondensable gases in condensers do accur,which hamper flow and deteriorate heat transfer.

Analysis and evaluation of non-condensable gas for auxiliary equipment of power stations

The influence of non-condensable gas on heat transfer performance of the single-row tube heat exchanger is analyzed.

Membrane separation processes with condensable gas such as water vapor removing from industrial gases and organic vapor recovery or separation are being developed recently and have great potential.
