Abstract for: Dust and Ash Plant Maintenance in power plant dynamics

Dust and ash plant maintenance management of the power plant plays a crucial role in the minimization of the environmental effects of the boiler residues through the efficient and effective removal of the dust and ash from the boiler. The objective of the study was to explore the relationship between the operation and maintenance systems. Extensive literature review, interviews of the subject-matter-experts (mental models) and maintenance data analysis were used to lay foundation of the system dynamic (SD) model. Operation and maintenance modelling was done using Sterman’s system dynamics research methodology. SD tool was used to demonstrate the negative effects of the misaligned operation and maintenance. Sensitivity analysis provided various scenarios that maintenance and operation managers can adopt for improved plant performance. Relationship between plant health, operations and maintenance management cycles was shown through simulation of the misaligned cycles between operations and maintenance management. Output of this research was that maintenance and operation have to be fully aligned in order to sustain excellent power plant performance throughout the generation cycle.
