Dedicated energy crops are agricultural crops that are solely grown for use as biomass fuels, e.g., short-rotation woody crops like hard-wood trees and herbaceous crops like switchgrass. These crops have very fast growth rates and can therefore be used as a regular supply of fuel. Biomass fuels are one of the most important energy resources. Biomass constitutes 14% of the global primary energy, the fourth largest following coal, oil, and natural gas. Biomass is the most important source of energy in developing countries, providing about 35% of their energy demand. Biomass wood fired boiler is designed with new type of biomass fuel combustion technology in the Europe for a higher efficiency.
In general, any organic non-fossil fuel can be considered a biomass fuel. Biomass for grate-firing can be mainly grouped into waste products and dedicated energy crops. Waste products include wood materials (e.g., saw dust, wood chips, wood logs, and bark), crop residues (e.g., wheat straw, rice straw, corn husks), and municipal and industrial wastes of plant origin (e.g., MSW, refuse-derived fuel (RDF), manure).
Biomass waste fired boiler has been developed to be used as agrowaste fired boiler for a wide world biomass fuel application.
The potential, on a global basis, to supply biomass for the production of renewable energy is assessed and reviewed in. Biomass fuels are also considered environmentally friendly. Firstly, there is no net increase in CO2for combustion of biomass if it is replanted. Biomass consumes the same amount of CO2 from the atmosphere during growth as is released during combustion. Secondly, firing biomass brings additional greenhouse gas mitiga-tion, by avoiding CH4 release from the otherwise landfilled biomass. CH4 is 21 times more potent than CO2 in terms of global warming, based on mass and a 100-year period. Thirdly, most biomass fuels have very little or no sulphur and, therefore, net SO2 emissions can be reduced if high-sulphur coal is...
