Figure 9: Drum Water Quality Display Panel i. Dynamic Simulation for Worst-case and Best-case values for Drum Water Quality on pH value ii. Dynamic Simulation for Worst-case and Best-case values for drum water quality on Sodium Phosphate as PO4 On the dynamic simulation process of sodium phosphate as PO4, the user views boiler panel displaying 43ppm of PO4 as a worst-case value, verifying erratic value, and this turns boiler parameter indicator red. A popup request shows as user clicked on the indicator bar to enters best-case value of 32ppm, which turns the indicator of the PO4parametergreen, validating the boiler operating in healthy condition. The PO4systemdesign specification is between 29-32ppm. iii. Dynamic Simulations for Worst-case and Best- case values for Boiler Drum Water quality on SiO2 b) Dynamic Simulation for Operational Feed Water Quality Parameters A dynamic simulation with test value worst-case and best-cases on feed water quality for iron (Fe) ppm, pH value at 25DegC and total dissolved solid (TDS) ppm were carried out and parameters displayed on the panel as evaluated and verified by fourteen (14) fertilizer boiler domain practitioners. Steam Package Boiler Expert System for Control and Maintenance of Fertilizer Plants Using Rule-Base Fuzzy Logic Global Journal of Computer Science and Technology Volume XXII Issue II Version I 35 Year 2022 ( ) C © 2022 Global Journals Figure 10: Ph Value of 10 Figure 11: PO4 Simulation Result Figure 12: Silica Max Simulation Result The results of the dynamic simulation process of the parameter of pH value range of 10.8-11.4 with worst-case pH of 10. The system displaying this value, less than the designed setpoint (10.8), turns red the boiler parameter indicator bar and user clicking gives the system popup request to enter the right value to validate that the pH value of 10 is erratic. Also, the boiler panel displays green as the user enters best-case functional of pH value of 11.2 and this validates the system after evaluation. The parameter design range of Silica max (SiO2) value is 0.0-4.0 ppm. The boiler water quality must remain within its setpoint for the boiler to function effciently as per design specifications. The results of the simulation with a worst-case of 6ppm, shows erratic display, verifying that SiO2is high, showing red on the indicator bar. Its requires a user to right value, 2ppm of SiO2, was entered, which turns parameter indicator bar green, validating the steam boiler running normally.
