Dynamic Model of a Boiler Adaptable to Green Fuels for a Heating System Daniel A. Morales Sandoval, Héctor Bastida, Muditha Abeysekera, Carlos E. Ugalde-Loo

Abstract

A mathematical model of a fuel combustion boiler suitable for system level studies of a heating system and adaptable to different combustible fuels is presented. The model considers the thermophysical properties of the flue gas and of the heat transfer fluid, mass flow rates and temperatures. To provide confidence into the modelling approach, the model was built in MATLAB/Simulink and simulation results were compared with results obtained with Apros. Results exhibited a good agreement between both software platforms under different mass flow rate conditions when methane and hydrogen were employed as fuels.
