A new condensate removal device that is saving the U.S. Navy at least $15 million per year in steam generation and maintenance costs can now be used to achieve substantial savings in commercial ship operations. The Flexitallic Drain Orifice, has proved effective as an energy saver in industrial steam lines from 1 to 2,500 psi and higher, although developed originally for 150 to 1,200 psi steam lines on U.S. Navy ships. The constant flow drain orifice has a stainless steel circular flat plate with a hole or orifice properly sized for operating conditions. The plate is held between spiral wound gaskets, one with an integral stainless steel strainer to prevent dirt and scale from eroding the orifice. The assembly is inserted between flanges in the steam line, and the flanges are bolted up. Application data is now provided so that any engineer can specify drain orifices for a steam system. The substantial steam losses that occur when a steam trap fails open, as it must for safety reasons, can now be avoided. A single steam trap that fails open at 5 psi wastes 117,500 pounds of steam per month. The same trap at 100 psi wastes 470,000 pounds per month. At a steam generation cost of $2 per 1,000 pounds, the fuel loss from this waste would be $235 to $940 per month. This new drain orifice cannot fail open and provides continuous stable condensate drainage.
