Flow is usually controlled by a steam trap or a solenoid valve, but bleed holes are sometimes used, often in conjunction with a solenoid valve.

The report said that excess sealant, previously used to repair a leaking joint, migrated to two steam trap valves used to drain excess condensed water, clogging them.

The simplest form of steam trap is a disc or short solid pipe nipple with a small hole drilled through it installed at the lowest point of the equipment.

The typical industrial facility can reduce this energy usage 20 percent ( according to the US Department of Energy ) by insulating steam and condensate return lines, stopping steam leakage, and maintaining steam traps.

At each outlet, however, there is a what is known as a steam trap, which, when it is working properly, allows air and water to pass into the return lines while keeping steam out of those lines.

However, Gifford said, steam traps often fail, allowing the steam to enter the return lines, where it then prevents the venting of air from radiators in nearby apartments, thereby making it impossible for steam to enter those radiators and heat them as it should.
