Study of Different Alternatives for Dynamic Simulation of a Steam Generator Using MATLAB

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