The steam/nitrogen mixture condensates and released the heat to the cooling water in the test section. The condensate water and un-condensed steam/nitrogen mixture at the outlet of test section enter a separator to separate the un-condensed steam/nitrogen mixture from the condensate water.
Condensate removal from plant. Often, the condensate which forms will drain easily out of the plant through a steam trap. The condensate enters the condensate drainage system. If it is contaminated, it will probably be sent to drain. If not, the valuable heat energy it contains can be retained by returning it to the boiler feedtank.
The reason is that at low inlet pressure, the steam mass flux provided by the electronic boiler is low. Under the same mass flow rate of cooling water, the steam at low pressure may get complete condensation in a certain location, where the condensation heat …

Summary: The following article is a part of the National Board Technical Series. This article was originally published in the Winter 1999 National Board BULLETIN. (4 printed pages) This article covers the four most common ways to "destroy a boiler," including fuel explosions, low-water conditions, poor water treatment, and improper warm-up.
What is Condensate? Condensate is the liquid formed when steam passes from the vapor to the liquid state. In a heating process, condensate is the result of steam transferring a portion of its heat energy, known as latent heat, to the product, line, or equipment being heated.

The steam released by the flashing process is as useful as steam released from a steam boiler. As an example, when steam is taken from a boiler and the boiler pressure drops, some of the water content of the boiler will flash off to supplement the "live" steam produced by the heat from the boiler fuel.
Carbonic acid can be found in small quantities in steam condensate, but shouldn't be a problem in most installations. It can be a problem if distilled water is used as the boiler fill. In that situation, as distinct from the flue gas situation, it comes from the natural solution of the carbon dioxide in the air in the pipes dissolving in the ...
