study realisation improvement has recently undergone extensive renovation and reconstruction work. Among ÅF’s most significant contributions to this work are the upgrade and improvement of the control system by implementing Balance+ in one of the gas boilers. Anticipated benefits include energy savings and simpler operation of the boiler. Balance+ helps guarantee stable boiler operation, and the control system is also capable of reacting to fast load changes, thus providing optimised steam production and energy generation. Saving resources, cutting costs Balance+ leads to savings in both resources and costs, mostly by helping to reduce the number of boiler trips and increasing operating hours, but also by improving boiler efficiency. The simplicity of the system and the reduction in operational disturbances also improve the working environment. The Balance+ control package developed by ÅF has been implemented at the Stora Enso pulp and paper mill in Hylte, Sweden.
