Abstract: The present study focused on analysing the availability of the boiler furnace system for the thermal power plant with Markov-based simulation. The boiler furnace has a substantial impact on the efficiency of the plant. The system comprises four subsystems: Boiler drum, Superheater, Economiser and Reheater. The study focuses on establishing an inclusive understanding of the boiler furnace system, including its design, operational parameters and historic performance records. In the analysis, many factors affecting availability are considered, such as maintenance practices, equipment failure and operations interruptions. The study quantifies the system's availability which is recorded in matrix tabulation form. The outcomes of the present study reveal that the boiler drum subsystem has the greatest influence on system availability.

Keywords: availability analysis; Markov-based simulation; performance modelling; boiler furnace system.
