PurposeThis paper deals with the optimization of coal handling system performability for a thermal power plant.Design/methodology/approachCoal handling system comprises of five subsystems, namely Wagon Tippler, Crusher, Bunker, Feeder and Coal Mill. The partial differential equations are derived on the behalf of transition diagram by using the Markov approach. These partial differential equations are further solved to obtain the performance model with the help of normalization condition. Numerous performability levels are achieved by putting the appropriate combinations of failure and repair rates (FRRs) in performance model. Performability optimization for coal handling system is obtained by varying the population and generation size.FindingsHighest performability level, that is, 93.33 at population size of 40 and 93.31 at generation size of 70, is observed.Originality/valueThe findings of this paper highlight the optimum value of performability level and FRRs for numerous subsystems. These findings are highly beneficial for plant administration to decide about the maintenance planning.

Abstract Coal handling system of Power plant(CHP) is easy to produce dust, which is the most serious place of coal dust pollution in thermal power plant. With the gradual improvement of national environmental protection requirements, the control of coal dust becomes more and more important. The author believes that we should not wait for the pollution caused by coal dust to be treated, but should take the initiative to attack, and should take the initiative to prevent dust, starting from the source of coal transportation. In the process of designing coal conveying of thermal power plant for many years, the author has carried out on-site investigation on many coal handling systems, summarized experience and obtained relevant data. Through further analysis, the main causes of coal dust are mastered, and the relevant measures of active dust control are put forward from the technical point of view, in order to provide help for the comprehensive control of coal dust in power industry.
