چکیده
In the face of threats related to energy supply and climate change, use biomass is gaining importance, particularly in distributed systems. Combustion biomass, including residue considered one routes increase share renewables generation. The modeling gaseous phase reactions remains crucial predicting combustion behavior pollutant emissions. However, their simulation becomes a challenging task due computational cost. This paper presents numerical analysis process gas mixture released during decomposition domestic 25 kW coil-type boiler. Three types biogenic fuels were taken into consideration. work aimed at examining available tools for burning, thus geometry system was limited only 2D case. thermodynamic equilibrium composition pyrolysis determined implemented Ansys simulate process. results showed potential detailed, but reduced, mechanisms CH4/CO/H2 mixtures main features. mechanism involving 85 appeared be more reliable compared that comprising 77 reactions, volatiles with higher H2 content, whilst offering an acceptable calculation time. burning characteristics obtained less CH4 are good agreement real operation conditions reported

CFD analysis of single-phase flows inside helically coiled tubes
It has been well established that heat transfer in a helical coil is higher than that in a corresponding straight pipe. However, the detailed characteristics of fluid flow and heat transfer inside helical coil is not available from the present literature. This paper brings out clearly the variation of local Nusselt number along the length and circumference at the wall of a helical pipe. Movemen...
متن کاملNumerical modeling of biomass combustion in a stoker boiler
Biomass fuel is considered a promising substitute for traditional fossil fuels. Amid a great variety of methods for converting the energy in biomass fuel into usable energy, direct combustion is still the dominant technology employed by industry. Because biomass fuel possess a much wider range of physical and chemical properties than fossil fuel, its combustion behavior is similarly diverse (an...
