  • Feedwater Preheaters | Cain Industries

    Feedwater Preheaters. A feedwater preheater raises the temperature of water before it enters a boiler for steam production. Boilers typically waste 18 to 22% of fuel combustion through exhaust stream gases. This waste heat is an excellent source of energy to preheat feedwater. Cain Industries' exhaust heat exchangers recover an amazing 30 to 50
