Steam Traps Conventional Condensate Receiver Tank Distribution System

Conventional Steam Traps

The above picture is an example of what usually happens to a steam distribution system with conventional steam traps over a period of time.

The problems and symptoms can range from mild to severe in a very short time depending on a host of variables such as:

A. Brand of steam traps.
B. Type of steam traps.
C. Usage.
D. Installation.

E. Maintenance.
F. Piping configuration.
G. Operating pressures.
H. Other variables

Starting in the boiler room (basement) note that the condensate receiver tank is venting an excessive amount of steam. In this particular example the condensate return lines appear to be full of condensate (water) although the temperature would be at elevated levels.

The reason for this is that steam is leaking past traps # 1, 2 & 3 but there is no room for flashing to occur, therefore the flash will occur at the condensate tank escaping out the vent to atmosphere. Usually caused by failed steam traps.

Note that traps # 4, 5, 8 & 9 are actually backing up condensate. Efficiency of individual heating units will be degraded depending upon the extent of condensate backing up usually caused by:

A. Improper trap style.
B. Excessive back pressure.
C. System anomalies.

Note that traps # 6 & 7 are functioning as designed, holding back the majority of steam while letting the majority of condensate out in a somewhat timely (although inefficient) manner. (Actual efficiency is dependent on brand and type of trap).

The overall end result is a steam system that is inefficient with uncontrollable temperatures and uneven heating throughout the facility. Caused by:

A. Overheated condensate return lines.
B. Control valves not always synchronized with associated trap.
C. Inefficient heating units caused by water logging.
D. Excessive back pressure caused by failed steam traps.

One way to keep a steam system from degrading is to continually monitor and repair or replace steam traps as they fail. (Very time consuming and expensive over the life of the steam distribution system, requiring skilled and knowledgeable personnel).

The best way to keep a steam system from degrading is to retrofit the entire steam distribution system with The Steamloc^® System. (Virtually maintenance free).

removal equipment (steam traps) one last time.
