1. A method for predicting a blowdown rate of one or more boilers, the method comprising:
generating, with a first model, output data specifying an empirical relationship between a plurality of input temperatures, a plurality of plant gas feed rates, and a plurality of outputs of the one or more boilers;
collecting an ambient operating temperature and a current steam demand of the one or more boilers;
comparing, with a second model, the ambient operating temperature and the current steam demand to the output data to determine a current required blowdown rate;
adjusting the blowdown rate of the one or more boilers according to the current required blowdown rate.
