Sewage Plant Boiler and Sludge Dryer Applications Gatineau Sewage Treatment Plant, Gatineau, Quebec, 1989

• 1989 – CHR-FLUE™ Dual Fuel NG/Methane Sewage Gas Boiler System. Heat recovered is utilized for continuous heating of sludge entering the anaerobic digesters.
• Achieved 30% to 40% annual NG savings
• Financial payback was 3.5 years (in 1989); however, based on today’s 2.5 x higher NG costs, it would be < 2 Years payback
