- Abstract
- Because of the complexity to describe and solve thermo-chemical processes occurring in a fuel bed in
grate-fired boiler, it is often necessary to simplify the process and use modeling techniques based on
overall mass, energy and species conservation. A comparison between two numerical models to
describe the thermo-chemical conversion process of a solid fuel bed in a grate-fired boiler is presented.
In this work both models consider the incoming solid fuel as subjected to drying, pyrolysis,
gasification and combustion. In the first approach the biomass bed is treated as a 0D system, but the
thermo-chemical processes are divided in two successive sections: drying and conversion (which
includes pyrolysis, gasification and combustion). The second model is an empirical 1D approach. The
two models need input data such as composition, temperature and feeding rate of biomass and primary
air. Temperature, species concentrations and velocity of the producer gas leaving the fuel bed
provided by the two models are compared. A sensitivity analysis with respect to mass flow rate of the
primary air is also performed, as well as a further comparison regarding the dependence of the
producer gas properties on the initial moisture content within the biomass. (literal)
