Introduction to biomass combustion systems

Combustion is an exothermic reaction that releases the chemical energy (HHV) of a fuel trans­forming it into heat that is transferred to the surrounding environment (combustion chamber) and to the combustion products (flue gases and ashes) (Obernberger, 1998). Combustion of a solid fuel is actually carried out as the exothermic release of the chemical energy contained in two different fuels: […]

Biomass gasification gas used for drying

Combustible components of biomass gases mainly contain hydrogen, carbon monoxide and methane. They could be used for combustion and providing heat for power plant or for driv­ing pyrolysis. Biomass gases can also be used for drying instead of flue gas (Yuan et al., 2005). Thus, it is a convenient method for self-sufficiency. When the biomass gases can be used for […]

OPERATING CONDITIONS OF IMPORTANCE FOR THE PRODUCT COMPOSITION

This section describes some important properties of significance for the product composition after gasification. 6.3.1 Fuel types and properties The performance and the selection of gasification technology are dependent on the characteristics of the fuel used. Therefore is a proper understanding of the characteristics of biomass and black liquor fuels important for a reliable selection and design of a gasifier. […]

CONCLUDING REMARKS

Biomass pyrolysis and gasification processes have been sufficiently developed to play a signifi­cant role in our sustainable energy future, especially as part of a biorefinery. While these processes can yield a number of gaseous and liquid fuels, this chapter provides a review of studies on the combustion and emission characteristics of syngas and biogas. There are notable differences between the […]
