摘要：

This work presents the simulation of a steam generator or water-tube boiler through the implementation in MATLAB(R) for a proposed mathematical model. Mass and energy balances for the three main components of the boiler-the drum, the riser and down-comer tubes-are presented. Three alternative solutions to the ordinary differential equation (ODE) were studied, based on Runge-Kutta 4th order method, Heun's method, and MATLAB function Ode45. The best results were obtained using MATLAB(R) function Ode45 based on the Runge-Kutta 4th Order Method. The error was less than 5% for the simulation of the steam pressure in the drum, the total volume of water in the boiler, and the mixture quality in relation to what was reported.
