Abstract

This study is focused on the steam boilers dynamics modelling used as a powerful instrument to predict the response of boilers to external inputs and transient operating conditions.

The article describes a mathematical simulation model that has been developed to study the stability of a steam boiler drum subjected to different initial operating conditions. The phenomenological study has been based on several simulations that have been done considering steam boilers characterized by different nominal values of both pressure and steam mass flowrate; the attention has been given mainly to the effect of different pumping characteristics and thermal flux values on the boilers stability. The article shows the main results of the simulations and lists all the boilers’ possible operating conditions, both stable and unstable.
