It is constantly be generated, increased and be detached from formation agitation in heat transfer wall for bubble, the liquid on heating wall is made constantly to be replaced, it can
To accelerate the rate of heat transfer of heat transfer wall, ratio of heat transfer coefficient greatly increases when not generating boiling.But if the bubble being detached from is too
Sheet of membrane mostly is formed in heating wall, heat transfer zone is covered by steam blanket, has obstructed contact of the water further with heat-transfer surface, and meeting
Influence heat transfer efficiency.Heat is only by the conduction of air film and radiant heat transfer, and heat transfer efficiency can substantially reduce, this phenomenon is known as film
Shape boils.The heat transfer coefficient of bubble boiling will be high times compared with film boiling, therefore controls the steam of boiling process generation
It takes away in time, avoids the occurrence of film boiling, to ensureing taking away in time for reaction heat, improve the combined coefficient of synthetic tower to closing weight
It wants.
