Modelling of selected waste biomass downdraft gasification
Апстракт
Gasification of waste biomass has double benefit since it presents an efficient and environmentally
friendly procedure to produce energy. Modelling of gasification of demolition wood
and coffee waste, and their mixtures, in downdraft gasifier is investigated. Air is exclusively
used as a gasification agent. A model for waste biomass gasification has been developed using
“Engineering Equation Solver” (EES). The downdraft gasification model, prepared within
this study, is an analytical semi-empirical model that can be used as a tool to analyse the
general trends of biomass downdraft gasification. The main characteristic and advantage
of this model are that involves main gasification sub-processes (drying, pyrolysis, gasification).
Also, the model is capable of dealing with a wide variety of biomasses (based on elemental
and ultimate analysis) and to predict its behaviors during a gasification process (yield and
composition of the products - producer gas, charcoal, and tar). Dif...ferent gasification process
parameters (temperature, equivalence ratio, air preheating) are varied and discussed in
order to define the optimal (qualitative and quantitative) yield of producer gas for each biomass
and their mixture.
