“…which is commonly considered in the freeboard of current domestic wood heating appliances [50,51,[123][124][125][126]. In some cases, the complexity of the homogeneous reaction model is further enhanced by also considering CO 2 dissociation [124].…”

“…has also been modeled in small-scale wood heating appliances [50,51,[124][125][126][127], since it is expected that hydrogen is one of the main compounds of the volatiles released during the devolatilization of a wood particle. The increasing importance of H 2 with respect to increasing temperature has been discussed earlier [19], and as such, it seems reasonable that a high temperature conversion processes, such as that occurring in e.g.…”

“…However, there are also other modeling approaches on how NO x prediction originating from fuelbound nitrogen can be modeled, without requiring a detailed reaction scheme. Huttunen et al [126] assumed that half the nitrogen in the permanent gas phase is NH 3 , which is a precursor for NO x , originating from fuel-bound nitrogen. The rest is assumed to be N 2 .…”

This paper reviews the current state of the art of numerical models used for thermochemical degradation and combustion of thermally thick woody biomass particles. The focus is on the theory of drying, devolatilization and char conversion with respect to their implementation in numerical simulation tools. An introduction to wood chemistry, as well as the physical characteristics of wood, is also given in order to facilitate the discussion of simplifying assumptions in current models. Current research on single, densified or non-compressed, wood particle modeling is presented, and modeling approaches are compared. The different modeling approaches are categorized by the dimensionality of the model (1D, 2D or 3D), and the one-dimensional models are separated into mesh-based and interface-based models. Additionally, the applicability of the models for wood stoves is discussed, and an overview of the existing literature on numerical simulations of small-scale wood stoves and domestic boilers is given. Furthermore, current bed modeling approaches in large-scale grate furnaces are presented and compared against single particle models.
