Jul 23, 2000 · A relief valve sized at not greater than 90% of the heat exchanger's maximum working pressure shall be installed on the water side of each steam/hot water heat exchanger and on both sides of water to water units. The relief valves must be installed at the heat exchanger

Condense Steam - an overview ScienceDirect Topics

The steam flow rate Fs is manipulated by a motor-driven valve whose position is controlled by an inner control loop. The steam condenses in the tubular heat exchanger W1 and the liquid condensate is pumped back to the steam generator. The water in the secondary circuit is heated by means of W1. How to Get the Most from a Condensate Recovery System Feb 12, 2020 · The removal of condensate from steam distribution mains is essential to maintain a safe and efficient central heating system. Allowing water to enter building mechanical rooms and get into the steam space of heat exchanger systems will reduce heat transfer and can lead to premature damage of flange gaskets, control valves and other components.

STEAM CONTROL AND CONDENSATE REMOVAL

enters the shell through a top vapor opening and surrounds the tubes inside of the shell. As the latent heat of steam is transferred to the medium inside of the tubes condensation occurs. The condensate then collects in the bottom of the heat exchanger shell and drains towards a bottom condensate Steam Control and Condensate Drainage for Heat The operation of the shell and tube heat exchanger is as follows. Steam enters the heat exchanger shell through the top vapor opening and surrounds the outside of the tubes. As energy is transferred through the tubes it heats the water inside the tubes. The heat transfer condenses steam inside the shell forming condensate that drops to the bottom of the heat exchanger shell. The condensate flows

Steam Control and Condensate Drainage for Heat

Jul 17, 2014 · The water-to-water heat exchanger design differs from a steam heat exchanger. The water-to-water heat exchanger has internal baffles to direct the water flow across the tubes to improve heat transfer. Water-to-water heat exchangers are externally distinguishable as the shell inlet and outlet tappings are the same size; steam heat exchangers have a large vapor opening in the top of the shell and a smaller condensate outlet in the bottom. The fluid in the condensate
