This paper shows the development of a model for an integrated gasifier and boiler unit. The feed to the gasifier is subject to composition changes that can disturb the entire operation of the system. As boilers need fuel feed with controlled composition, it is very important to develop a simulator for the system so that the operation can be investigated and a control system be further proposed. A simulator was developed based on models from the literature. Tests were performed in the system, first considering each unit separately and then integrated. The results provide a description of the behavior of the output variables of the boiler considering the presence the disturbances in the gasifier.
