STEAM TRAP
EDUCATION CENTER

In this coal fired power plant, soot blower drains are used to remove condensate from the soot blower steam system. This steam main is a high pressure / high temperature line in the plant. The steam soot blowing system is installed on each side of the boiler. The steam traps are installed at either intermediate stages on the side of the boiler, or at the bottom of the boiler. Soot blower drains are situated on this line to remove start-up loads, hot running loads, and cool-down loads.

On soot blower drain applications, the best steam trap design in the marketplace is the Velan Multi-Segmented Bimetallic Steam Trap. The soot blower drain application will have a “large” start-up curve, followed by a “moderate” hot running load. The only other load that will be encountered will be a “large” cool-down load when the line is de-energized.

Due to the fact that soot blower drains can be very high in pressure and temperature, customers weld these applications. Velan offers steam traps and “Piping Kings” in for soot blower drains in A105 Carbon Steel.

Velan will offer the “N” Series or “SPF” Series steam traps for soot blower drain applications.
