  • Kearl ConDex Flue Gas Heat and Water Recovery Project …

    This project will demonstrate ConDex boiler flue gas and water recovery technology at Imperial's Kearl Oil Sands mine. The ConDex technology is designed to reduce greenhouse gas (GHG) emissions by capturing and using exhaust heat otherwise lost to the atmosphere through the flue gas streams in oil sands mining operations.Learn More

  • Condensing boiler - Wikipedia

    Condensing boilers are water heaters fueled by gas or oil. They achieve high efficiency (typically greater than 90% on the higher heating value) by condensing water vapour in the exhaust gases and so recovering its latent heat of vaporisation, which would otherwise have been wasted. This condensed vapour leaves the system in liquid form, via a Learn More

  • RECOVERY OF WATER FROM BOILER FLUE GAS

    The results showed flue gas water vapor condensed in the low temperature region of the heat exchanger system, with water capture efficiencies depending strongly on flue gas moisture content, cooling water inlet temperature, heat exchanger design and flue gas and cooling water flow rates.Learn More
