CONDENSATE RETURN SYSTEMS

When steam has performed its work in manufacturing processes, turbines, building heat, etc. it transfers heat and reverts back to a liquid phase called steam condensate.  However, not all the energy used in producing steam is lost when condensate is formed.  

As most condensate return is still relatively hot (130^OF to 225^OF) , it is very valuable as a source of feedwater.   

There is a significant fuel savings related to the heat required to raise the temperature of makeup water at (50^OF to 60^OF) to equal that of the return condensate, not to mention the additional cost in pretreating (softening) the makeup, as well as basic water cost itself.
