Innovative New Chimney Design for Wet Flue Gas

NACE Portland / April 2008 – Paul Nederlof, Hadek Protective Systems


For removal of a large number of flue gas components, wet air pollution control (APC) equipment is often chosen as the best available technology. Low flue gas temperatures produced by these systems warrant the need for consideration of corrosion control in the flue gas systems, downstream of the wet APC-systems.

This paper will present an innovative New Chimney Design. The design consists of a concrete shell and a borosilicate glass block lining without an internal flue reducing the outside chimney dimensions and time to build the chimney considerably. Cost of the different options will be discussed, taking into consideration construction schedules, manpower requirements, and local design restrictions to provide a realistic comparison basis for the respective design options.
