In the operation of modern boiler plants enormous demands aremade in terms of the safety engineering and on the economic useof the fuel. With ServiceLab, the commissioning tool for SIMATICand SIPART DR, the process data can be recorded via the openand closed-loop controllers and their parameters optimized quicklyand easily.
The product range of STANDARDKESSEL, the leading constructor of industrial boilers, includes large volume boilerswith steam generating capacities of over 200 tons per hour, but also waste-heat boilers at every level of output that aremanufactured with or without additional firing mainly for industrial and combined-cycle power plants. While smallersystems are usually equipped with conventional contactor controllers, the larger systems such as those in industrialpower generation plants use SIMATIC S5 controllers. The often very complex relationships between fuel use, air volumeand load are optimally balanced with one another using SIPART DR 24 controllers.
The time spent commissioning such plants on site at the customer premises represents a cost factor that it is essentialto minimize. For this reason, the open and closed-loop controllers are preset prior to shipment of the components. Bysimulating and preconfiguring the control loops with ServiceLab, the system optimization work required on site is reducedto a minimum. The program permits the visualization of the processes and allows access to all essential system parameters.The recorded data can be stored in realtime and evaluated graphically. This enables unstable control loops or faults in thecontrol sequence to be readily detected, even at the simulation stage.
