EPOC® Load Hierarchy Management
In some plants, two or more boiler lines are operated in parallel. These boilers feed into the same high-pressure steam line. Parallel operation often leads to “swinging up” of the boilers and in extreme cases even to their failure. Traditionally, this problem is solved by a guide boiler. However, this results in efficiency losses because the other boiler(s) are not fully utilized. In contrast to the classic solution, EPOC® Load Hierarchy Management calculates all load setpoints in a superordinate manner so that boiler efficiencies are maximized.
In addition, the load setpoints react much faster to steam disturbances in a coordinated manner. EPOC® Load Hierarchy Management allows you to save fuel while maintaining performance, thus reducing your costs. Your plant achieves its optimal overall efficiency by optimising the energy use of different energy sources and by using energy buffers in your system. You also reduce the emission of greenhouse gases.

Sebastian Sturm is your expert when it comes to the EPOC® Suite!
The integration of the control of the peak load boilers ensures the optimal feeding of one or more peak load boilers. The feed-in times can be defined precisely, depending on the plant and supply criteria. In the event that several peak load boilers are available, their sequence during activation is also controlled. In addition, a “soft” feed is implemented to prevent the displacement of biogenic heat generators.
