Abstract:

With the continuous increase of heating load of the generator units in recent years,the water vapor quality of the units becomes worsened,higher than the standard values specified in GB/T 12145-2008. The structure,installa-tion and application situation of the degassing membrane device are introduced in the paper,providing solution schemes for the problems of vapor water quality in heat supply units with high capacity.

Key words: boiler make-up water, degassing membrane, oxygen removal, vacuum, sweeping
