Boiler load allocation Boiler load allocation tries to divide the generation of the required steam between the boilers so that generation costs are minimum. From this point of view, two boiler types exist: process boilers whose production rate depends on the mill operation. They have a limited potential for energy management. Recovery boilers belong to
