to Amit (2012), the impurities found in boiler water depend on the untreated feed water quality, the treatment process used and the boiler operating procedures. a) Expert System Theory Generally, the higher the boiler operating pressure, the greater will be the sensitivity to impurities. Therefore, the American Trainco, Inc. (2006), states operators (users) are responsible for control and maintaining the boiler in a safe and efficient manner with sound engineering practices and manufacturer’s specified maintenance procedures. Mrudula (2013) describes different types of expert systems. They are rule-based expert system, fuzzy expert system, frame based expert system, and hybrid expert systems, many expert systems are in real use and in the future one is likely to see more expert systems packaged with domain knowledge being sold. Amit (2012) added that boiler devices comprise of feed water system, steam system and fuel system, and that industries worldwide are going through an increasing and stiff competition and increased automation of plants, like the Ovation expert system. Seán et al., (2014) suggested in their paper that an expert system performance could discover excessive levels of blow down in steam package boilers, and diagnose the reason, which could be related to feed water conductivity, or component issues, which becomes necessary and in line with the main area were this dissertation is providing solutions. b) Expert System Research on Maintenance Edgar et al., (2010), contributed by developing an expert system for fault diagnostics in condition- based maintenance and that the goal of the system is provided to the non-experts in industrial maintenance with a list of possible failure modes, decisions to be adopted. Affirmed by Nwaibu & Adeyanjo (2012), is the development of user centered design approach to situation awareness which if applied to system will certainly aid the operation of the system. Cucu et al., (2009) examining the causes of equipment failure and malfunction been a central application field of expert systems or of data bases, in general, Chee et al.,(2016), exploits the enhancement of expert systems in engineering, and therefore, an expert system implies into the engineering and manufacturing process can provide greatest assistance for operational workers during performances and deal with critical and important tasks. Bretz (1990) discussed on a comprehensive expert system that assists in power plant boiler failure analysis and the maintenance planning subsystem automatically prepares daily repair schedules, a work estimation plan, and work specifications. Konstantin, et al., (2020) discussed that ES are very advantageous for steam turbine unit (STU) diagnosis. c) Expert System Research on Control Emerson Process Management Power and Water Solution Inc (2011), Ovation expert system was designed to help you achieve operational excellence and create a sustainable competitive advantage, with standard hardware platforms, operating systems, and network architectures. Krishan (2016), proposed a fuzzy expert system, using fuzzy control design a simulation system of fuzzy logic controller for water tank level control by using simulation package which is Fuzzy Logic Toolbox and Simulink in MATLAB. Anabik & Denis (2012), on boiler temperature and water control, designing an expert system, using fuzzy logic on FLC based boiler control, the proposed method consists of two sections. first section is to develop a steam temperature monitoring and control system and the second section consists of water level control. For both sections Fuzzy Logic Control will be used. Celin et al., (2016) proposed modeling and control of a 200 MW power plant using the embedded fuzzy approach. The embedded fuzzy based boiler control consists of models, and the output of the network is the interpolation of the models’ using memberships. In line with power evaluation and control, a fuzzy based expert system named Nuclear Power Plant Operator Evaluation Expert System (NPPOEX) is one of the latest expert systems which shows the use of expert system techniques in the personal evaluation process, Yangping et al., (2011). Harald & Georg (2015) proposed Expert Systems (ES)– Smart Solutions for Power Plants that can support operators and engineers in different areas. Monitoring systems like SR::EPOS enable continuous gathering and analyzing of data and thus can help to detect various problems very fast to avoid a reduction of efficiency or damages Marco et al., (2003) and Tavira-Mondragón et al.,(2011) agreed that Control remaining the center of operations in the industries, Seán et al., (2014) said operator expertise is generally capable of reacting to faults and performing corrective measures, guidance using expert systems will improve operation and reduce downtime. III. M ethodology According to Anne (2013), when conducting research or degree projects, methods and methodologies are essential to plan and steer the work to achieve proper, correct, and well-founded results, and on disciplines within computer sciences, the focus is often on the work with the research rather than methods. To produce a good system that will meet functionality and performance for users in boiler control and maintenance for fertilizer plants, the researcher 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 26 Year 2022 ( ) C © 2022 Global Journals
