Steam Drum Section Replacement

In February of 1998 Troy Boiler Works began a complete circumferential replacement of a center section of the steam drum of a 100,000 #/hr Erie City water tube boiler. The boiler, with a design pressure of 922 PSIG (at 565 degrees F), supplied steam for an area paper plant.This replacement was necessary because of a heat stressing in a section of the original drum. A replacement boiler would have been much more costly, and would have taken many months to arrive at site.

Repairs of this type are one of a kind so many factors had to be considered in this critical work. This included bracing the original structure before cutting out the bad section, forming and machining the new section, properly beveling the new and old sections, rigging the new section into place, aligning the drum sections, properly welding the drum sections together, and heat-treating the weld areas in place.

When all was said and done, the steam drum was within 1/16" level along its 40' length and the customer's equipment was back on-line, safely running with a quality repair.
