OSTI ID:5228891
A flue gas cleaning system now being used on two 360 Mw coal-fired boilers in Montana features a wet scrubbing system used for removing 99.5% of the particulates and 70-75% of the sulfur dioxide (the captured ash provides alkalinity for removing the sulfur dioxide, replacing about 22,000 tons/yr of lime for the two units) and a closed loop water system. This equipment also lacks a flue gas bypass around the scrubbers. Designed to meet federal new source performance emissions standards, this system has operated successfully for approximately two years at the Colstrip Station of the Montana Power Co. and the Puget Sound Power and Light Co. The system supplier for the scrubber installation was Combustion Equipment Associates Inc. The development, operation, and performance of the Colstrip flue gas cleaning system are described in some detail.
