5.1.1  Heat rejected


Equating the total heat per kilogram of steam leaving the boiler h, with subsequent heat losses hr, hb, hg, and the heat equivalent of turbine-generator work output hw, then the heat at the turbine exhaust he can be represented by the equation:

The heat flow rate rejected to the cooling water ะค, is found from the equation:

Added to this is any heat rejected by drains from feedheaters, etc., which may be discharged within the condenser.
