Industrial Boiler Optimization Toolkit - SlideShare

Boiler Optimization - With a boiler's firing rate held constant, feedwater pressure and flow affect boiler pressure. As electricity demands change, so do associated boiler loads. When more electricity needs to be generated, the boiler produces more steam, therefore feedwater flow must be increased to the boiler.
