“…19 The positive effect of vibration on condensation has also been reported elsewhere. 23,24 A common feature of the above reports is they are limited to a specific frequency strongly related to the drop size. This is due to the low damping effect from reduced adhesion force between a hydrophobic surface and droplets.…”

A mass-spring-damper theoretical model with a phenomenological equation is established to clarify the underlying physics of the dynamics of droplets on a vertical surface driven by vibration. It is found experimentally and theoretically that the phase shift between droplet and plate appears and peaks at a lower frequency for a larger droplet. At a certain frequency, two droplets could move in the opposite direction. Based on the phase shift mechanism, we propose a strategy aimed at promoting droplet coalescence. Compared to the necessity of precise control of frequency for resonance-induced events, the strategy accepts a higher tolerance for frequency, at which opposite-motion-induced droplet coalescence could occur. The optimal frequency where there is a maximum phase shift between two droplets is derived, and a large-bandwidth frequency range, which allows at least 90% maximum phase shift, is defined. The good agreement between the experimental and theoretical results collectively shows that the motion of the larger droplet is in the opposite direction to that of the smaller one only at large-bandwidth frequency range and the two droplets coalesce with high enough amplitude. Our findings are helpful for the utilization of vibrating surfaces for droplet removal.

“…The separated secondary steam condensate recovery system represents a condensate recovery system that uses a secondary evaporator to separate the secondary steam so that there is no steam in the condensate pipe. The non-separated secondary steam condensate recovery system represents the condensate recovery system that does not separate the secondary steam, and there is a condensate recovery system in which steam and water flow together in the condensate pipe [6]. Finally, it should be pointed out that the actual condensate recovery system in steam heating projects is often not a single type of system, but a composite recovery system composed of multiple types.…”

The paper starts with calculating the share of heat of condensate in thermal power plants in the total heat of steam, expounds the purpose, significance, and principle requirements of condensate recovery. Introduces the composition and classification of condensate recovery system, proposes technical and economic indicators for condensate recovery, and derives them a simple algorithm for the benefit of condensate recovery is presented. Finally, two calculation examples are used to illustrate the considerable benefits of condensate recovery.
