The pseudo bond graph technique is used to build a non-linear mathematical model of a large scale marine boiler. This paper describes in particular the modeling philosophy, the construction of constitutive laws for double bond C-fields in drum, risers, superheaters using several curve fitting methods, and the systematic formulation of system equations through the study of causality. Attention is paid in adjusting the system parameters so that a reasonable steady state and a satisfactory dynamic behavior of the model are obtained. Results of the simulations are presented, comparisons with those given by conventional modeling techniques are made.
