Quantum Consulting Engineers provided structural engineering for the boiler superheater upgrade project at the Burnaby MSW Plant in British Columbia. Montenay Inc. operates a municipal solid waste incinerator plant. The goal of the project was to improve the plant’s energy efficiency by raising the steam temperature of their three boilers to an efficient level for the plant’s new steam turbine-generator. This required process and design engineering for the new superheater and boiler pressure part modifications.

One of the structural design challenges involved supporting the new 100,000-pound superheater’s gravity and seismic loads from the top of the existing boilers’ upper sidewall headers. This was required to accommodate the upward expansion of the 50-foot tall bottom supported boilers. Dual purpose transportation and lifting cradles were also designed by Quantum to support the 40-foot long superheater sections during shipping and erection by overhead crane down through the roof of the building.
