Due to its complexity, a high-fidelity model such as NETL's 1D/3D hybrid fire-side boiler model should be developed first based on a given geometry of the furnace. A surrogate model could then be generated from the results of multiple high-fidelity model simulations sampled in the input space of the high-fidelity model.
