A previously‐described model of transient boiler operation is improved in its treatment of boiler controls and applied to the analysis of upsets in a special‐purpose boiler. The improved treatment of controls enables the model to more realistically predict the boiler response during upsets. Thus, the model is useful in indicating whether the boiler can be kept under control during particular upsets and whether the excursions of key operating variables can be held within allowable limits. The present paper describes the mathematical formulation used to model the boiler's control systems, the characteristic behaviour of these systems and the results of some specific analyses of upsets. It is concluded that the mathematical model of control systems, although simple, provides a useful representation of control‐system behaviour, and that incorporation of these techniques into the earlier‐reported model provides a significant enhancement of the model's ability to analyse boiler problems and performance.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
