The main combustion parameter is the excess air ratio (ì) that describes the ratio between the locally available and the stoichiometric amount of combustion air. For typical biomass, the combustion reaction can then be (4) Nussbaumer, T. Schadstoffbildung bei der Verbrennung von Holz, Ph.D. Thesis 8838, ETH Zu¨rich, 1989.
Biomass combustion such as burning fuelwood to provide heat, power, or combined heat and power (CHP) is a link in the energy chai n from producing renewa ble biomass resources to providing sustainable services in the form of heat (or refrigeration), shaft power and
Figure 4.1 is an overview of the processes ending with the production of heat and power from the combustion of solid biomass fuel. Each of these processes has an effect on the condition and combustion properties of the biomass fuel or on the availability of the biomass and its effect on plant economics.
Direct combustion is the best established and most commonly used technology for converting biomass to heat. During combustion, biomass fuel is burnt in excess air to produce heat. The first stage of combustion involves the evolution of combustible vapours from the biomass, which burn as flames.
Combustion of biomass used to heat greenhouses. Fire, or combustion of biomass, is arguably the oldest known and most widely used controllable energy source on earth. In recent years, rising costs of fossil fuels and the development of advanced equipment have made biomass combustion an economical, efficient, and practical energy source.
Direct combustion is the most common way of converting biomass to energy - both heat and electricity- and worldwide it already provides over 90% of the energy generated from biomass. Direct combustion of solid biomass fuel is well understood, relatively straightforward, commercially available, and can be regarded as a proven technology.
Combustion is complete when 100 percent of the energy in the fuel has been extracted. It is important to strive for complete combustion to preserve fuel and improve the cost efficiency of the combustion process. There must be enough air in the combustion chamber for complete combustion to occur.
Is Biomass Combustion Right for Me? If you have access to suitable feedstock, along with a place to store it, biomass combustion systems can be an attractive option, saving you money compared to conventional fuel systems. However, keep in mind they require more maintenance and oversight.
Properties of biomass relevant to combustion are briefly reviewed. The compositions of biomass among fuel types are variable, especially with respect to inorganic constituents important to the critical problems of fouling and slagging.
