    utilizing waste heat to produce electricity

    I work in pulp & paper industry. We loose a lot of energy (~150°F hot air and condensing steam), from dryers, through the roof vents. Could I use Kalina-cycle (ammonia/water) turbine or a Stirling engine to recover this heat and utilize it to produce electricity? Any suppliers of the equipment?

    GET RID OF LOW GRADE HEAT

    How about just injecting room temperature compressed air in water? The air will cool down water as it decompresses. And a bit of evaporation should help too.
