Experimental Study on Flooding Rate in Inclined Reciprocating Condensers

摘要

The flooding rate may directly influence the condenser's efficiency and safe operation, so it's of great significance to study it in condensers. We built a experimental setup to study the flooding rate in the condensing tubes with different inclinations. Based on large experimental data and calculation, we put forward formulae of flooding rate, modified the flooding rate formulae proposed by the Pre-Soviet scholar Alekseev, pointed out the factors that affect the flooding rate and the way to increase the flooding rate. The experimental results show that: the flooding rate in the reciprocating condensers is relevant to the physical parameters of the gas and liquid phase mediums, the section size and shape of the condensing tube and the inclination of the condensing tube; with the section of the condensing tube is ellipse or rectangle, and the major axis is vertical to the ground, the flooding rate is larger than the rotundity shape; when the condensing tube is inclined, the flooding rate is lager than the case when the condensing tube is vertical. According to the medium and section of the condensing tube, the flooding rate is maximal when the condensing tube is inclined at an angle between 45 and 65 degree; when the steam medium is certain, the flooding rate may apparently increased with the changing of the section of the condensing tube and the inclination to the ground.
