Objective The conventional modelling of solid fuel devolalilisation fails in the case of biomass to depict its diversity from coal as well as between different types of biomass. To alleviate this problem, extensive, repetitive and most of all very expensive combustion trials for each single type of biomass must be performed at large and full industrial scale furnaces in order to characterise its combustion behaviour. An appealing alternative can be the use of CFD mathematical models; they are becoming increasingly popular while at the same time they receive the scepticism of the power generation and high temperature process industry. This scepticism is a result of the fact, among others, that each type of biomass fuel has a different and very complicated chemical structure thus its simulated behaviour by the relatively simple devolatilisation and combustion models currently in use by CFD codes is associated with a great degree of uncertainty. To address this problem, there are current trends to incorporate more elaborate sub-models into the codes for the thermal decomposition and combustion processes (devolatilisation, secondary cracking, soot formation etc.) for different types of coal or coal blends but they are cumbersome, and computationally uneconomical. Furthermore, biomass has been much less investigated due to the relatively recent interest in its industrial utilisation as a fuel. This project applies the newly emerging neural network technology to enable the more generalised prediction of biomass devolatilisation behaviour. The technology will be used to predict the volatile release rate from selected key biomass characterisation parameters and the local physical and thermal conditions in the near burner field. The new formulation will be tested against bench-top data and then incorporated in a reputed in-house CFD combustion model where it will be validated against data taken in a large scale furnace.
