Boiler Generation Project Examples
Summary
Evergreen has completed thousands of projects, ranging from numerous custom retrofits in existing industrial
facilities to complete greenfield manufacturing plants. Of these projects many have included boiler systems
and related thermal and piping systems. In several instances, the boiler burners had to have the flexibility to
operate with alternative fuels, e.g., natural gas, propane, oil, wood, etc. A few projects that illustrate our
relevant experience are summarized below.
Thompson River Co-Gen, LLC – Thompson Falls, Montana
For this 17 MW coal fired cogeneration project, Evergreen provided the design for the turbine island piping
including extraction steam, hot well, feedwater heaters, cooling tower, condensate, lube oil, and other
systems. We also provided civil structural design of the cooling tower basin, utility tunnels, and various
service platforms. In addition, we provided all the power distribution including the primary substation and
over land transmission line to tie-in to the utility grid.
Wah Chang – Albany, Oregon
At a rare metals production facility, Evergreen provided electrical engineering and design for six 2.8 MW
gas reciprocating engine generators with heat recovery steam generators (HRSG). Evergreen provided
engineering and design of the HRSG and steam system.
Weyerhaeuser – Springfield, Oregon
250,000 pph package boiler, 650 psig/700ºF, natural gas, with all auxiliary systems. New installation of
power boiler at existing paper mill, tied-in to existing steam systems to provide supplementary steam power.
Evergreen provided all engineering design and documentation, including design, drawings, specifications, bid
packages, etc., as well as field technical supervision during construction.
Evergreen also provided engineering design and documentation for burner conversion on a power boiler and
prepared P&IDs for steam and condensate systems including four steam turbine generators.
Georgia-Pacific – Monticello, Georgia
Greenfield medium density fiberboard plant. Evergreen provided all engineering, including specification,
selection, and design for installation of a 50,000 pph/300 psig package boiler to provide process steam and
thermal energy for the plant.
Evergreen provided all engineering design and documentation, including design, drawings, specifications, bid
packages, etc., as well as field technical supervision during construction.
Murphy Plywood – Sutherlin, Oregon
Major retrofit projects for a 35,000 pph/250 psig boiler and ancillary systems. Projects included steam and
condensate system modifications, burner replacement (gas and sander dust), piping, etc.
Morgan Products – Springfield, Oregon
Provided all engineering, including design, equipment selection, and site installation support for temporary
package boiler installation at an existing door manufacturing plant.
University of Oregon – Eugene, Oregon
Provided civil/structural and piping design support to Systems West Engineers for multiple boiler and turbine
installation at the University of Oregon in Eugene, Oregon. New 70,000 pph boiler installed in existing power
plant and tied into power generation systems.
Trus Joist – Stayton, Eugene, and Junction City, Oregon
Provided all engineering support for new thermal oil systems for process heat at three plants. Involved
burner, piping, pumps, instrumentation, heat exchangers, etc.
