This abbreviated Steam Table gives the boiling point of water at various pressures, and the available energy at those pressures. Steam in contact with water (saturated steam) will remain at this temperature as more heat is added. The added heat just produces more saturated steam. A boiler with no superheater will operate at the saturated steam temperature for the given operating pressure, with increased firing producing more pounds per hour of steam.

Saturated steam in a boiler can be separated from the water, then reintroduced into the boiler. This “dry steam” can then be raised above the saturated steam temperature, or superheated, often to 1000 Deg. F or more. The superheated steam contains much more energy than saturated steam at the same pressure, so superheaters are common features of larger industrial and utility boilers.

At the supercritical temperature and pressure, water and steam become a high energy plasma, with no distinction between water and steam. This plasma can also be superheated. A few very large utility boilers operate under supercritical conditions.

]]> http://www.heckmantube.com/?feed=rss2&p=139 0 Comparison of Standards http://www.heckmantube.com/?p=136 http://www.heckmantube.com/?p=136#comments Tue, 23 Mar 2010 12:58:23 +0000 admin http://www.heckmantube.com/?p=136 This table is intended to give a “quick and dirty” comparison of American, British, German, and Japanese Standards for common boiler tubing and boiler piping specifications. This table must not be used for design. There is seldom an exact match between specifications in two different Standards. Use this table only to find an approximate equivalent, then compare the details of the specifications to determine if substitution is permissable. The best source I have found (and it’s neither completely accurate nor easy to use) is the Handbook of Comparative World Steel Standards, published by ASTM. It’s a revision of a handbook originally done by the Japanese, and it’s still half in Japanese, but it seems to be about the only thing available, short of buying all of the individual Standards. You can buy it off the Web atwww.astm.org. Click on the Bookstore, then Technical Publications, then Steel. You may have to up the credit limit on your plastic.

The table is divided into tubing, (which is used inside the boiler setting, as in steam generating tubes, wall tubes, superheaters and economizers) and piping (which is used ouside the boiler setting, as in headers, steam piping, and feedwater lines). The German (DIN) Standards don’t appear to differentiate between the two. Heat exchanger tube specs are not included here. In general, the Japanese (JIS) specs match up pretty well with the American(ASME/ASTM), while the British (BS) and German specs are usually more difficult to find an equivalent in.

We welcome input on any poor choices, downright errors, or blank spots in the table. Please email your comments to steve@heckmantube.com.
