Do all steam heat exchangers require the installation of steam traps, and what are the standard criteria for this? If multiple heat exchangers are connected in parallel, does each one require its own drain trap?
:Lol, there are definitely experts who will answer your question. What I want to say is: your profile picture is so cute.
It still depends on your process steam consumption. If too much steam is used, it is also possible to control it with a float instead of a steam trap. The steam consumption is relatively low, so installing a steam trap is a simple solution. When multiple heat exchangers are used in parallel, a drain valve needs to be installed on each one, in order to prevent steam from flowing between individual heat exchangers and resulting in inadequate heating.
As an additional note, the traps and blowout valves installed on each heat exchanger not only serve to drain water but also help in testing and checking the operating condition of the heat exchanger.
It has nothing to do with standards. Heat exchangers are required by the process requirements; it’s essential to meet the process’s needs regarding heat transfer. If the condensate water cannot be removed in a timely manner, it will affect the efficiency of heat exchange. Do you think it’s necessary to add one?
When multiple heat exchangers are connected in parallel, a drain valve must be installed on each one separately, as the pressure drop across each heat exchanger varies. Using a single drain valve may result in condensate not being able to be removed in time, thereby affecting the heat exchange efficiency. There’s no need for the poster to worry about saving a few steam traps; compared to the requirements of the equipment and the manufacturing process, the cost of steam traps is really insignificant
Mm-hmm, thank you. There’s one more thing I’m not quite sure about: aren’t traps generally used to remove liquids and non-condensable gases? For example, if a heat exchanger is heated by a medium at 260°C and by steam at 290°C, and the steam completes its heat exchange process normally, isn’t it non-flammable? Then, if a trap is installed at the outlet of the heat exchanger, wouldn’t that prevent further heat exchange?

Another question: does each parallel heat exchanger’s inlet fluid require its own separate set of steam control valves? ?
