Montenay Inc. operates a municipal solid waste (MSW) incinerator
plant located in Burnaby, British Columbia. The facility operates three
essentially identical boilers that were designed to generate slightly
superheated steam at 248°C (478°F) and 3,140 kPa (455 psig).
The plant was originally sized to supply process steam for export to
an adjacent industrial plant. The fraction of steam that was exported
decreased in recent years to about 35% of the production with the remainder
being condensed. This has caused Montenay Inc. to initiate a power generation
project with the goal to improve the plants energy efficiency and generate
additional revenues by purchasing and operating a steam turbine generator.
A superheater upgrade was required to raise the final steam temperature
to a level that was suitable for use in an efficient steam turbine-generator.
Jansen Combustion and Boiler Technologies Inc. (JANSEN) was contracted
to perform the process and design engineering for the required boiler
The project work included defining target process conditions, deriving
conceptual design options, sizing the new superheater, deciding on material
selection, preparing equipment specifications, and supplying the fabrication
and installation drawings.
The boiler modifications has been implemented in all three units in
spring 2003. Power production will start in early summer 2003.
