The Canadian pulp and paper industry has lately begun to shift its environmental focus. Having met or bettered their commitments regarding effluent discharge, many mills are now turning their attention to airborne particulate emissions and odor control.
cogeneration componentsSandwell’s turnkey cogeneration project for Finlay Forest Industries Inc. in Mackenzie, British Columbia is an example of the commercial advantage to be found in meeting environmentally driven technical requirements. The 14 MW cogeneration plant provides an alternative to beehive burners as a method of sawmill residue disposal, and a source of power to augment the high electrical requirements of the CTMP plant. The steam generated satisfies the mill’s entire process and utility steam requirements.
The project’s centerpiece is the ABB woodwaste-fired bubbling fluidized bed boiler, capable of producing 228,000 lb/hour of steam at 950 psig/900° F. The boiler’s unique characteristics make it ideally suited to handle the high moisture content typical of sawmill residues and secondary effluent treatment sludge.
