This month, I will continue to discuss the forgotten skills of steam system design. Last month, I touched on several topics, including high- and low-pressure steam, boilers, deaerators, boiler feed receiver/pump sets, condensate receiver/pump sets, vacuum pumps, schedule 40 and schedule 80 piping, 100% outside air unit steam components, and steam humidification.
This month, I’ll focus on equipment that design engineers used to draw upon back when steam heating systems were more common, such as steam-to-hot water heat exchangers. These shell-in-tube heat exchangers transferred steam heat to hot water supplies that would serve baseboard finned tube radiation, convectors, and unit heaters as well as fan coil units and unit ventilators.
