Minimize Controllable Feedwater Heater Losses Through Heat Rate Awareness

A feedwater heater is a device used in a power plant to pre-heat water being delivered to a steam generating boiler. Preheating the feedwater prior to steam generation improves the thermodynamic efficiency of the system. Heat rate is a measure of how efficiently a power plant uses heat energy. You can measure heat rate by the number of BTUs the power plant requires to generate a kilowatt hour of energy. As your heat rate goes up, so do your fuel costs. Considering fuel expenditures account for 70 to 80 percent of production costs and millions of dollars per year, improving heat rate one percent could generate five hundred thousand dollars in annual savings for a 500 megawatt power plant.

To contain fuel costs, power plants must maximize the efficiency of their feedwater heaters. That's why many companies today are focusing on improving heat rate as a way to use their feedwater heaters more effectively and significantly reduce their fuel costs.
