Structure and also structure of biomass molding fuel
Biomass molding fuel is composed of combustible issue, not natural issue and water. It has carbon (C), hydrogen (H), oxygen (O), a percentage of nitrogen (N), sulfur (S) and also other elements. It also includes ash as well as dampness.
C: Biomass molding fuel contains less carbon (concerning 40-45%), particularly set carbon, which is easy to shed.
H: Biomass molding fuel has high hydrogen web content (regarding 8-10%) as well as high volatile content (concerning 75%).
S: The sulfur web content of biomass molding fuel is less than 0.02%. There is no demand to mount a flue gas desulfurization gadget when burning, which lowers the expense of desulfurization as well as is beneficial to environmental protection.
N: Nitrogen material in biomass molding fuel is less than 0.15%, as well as NOX discharge depends on the requirement.
Ash: Biomass molding fuel makes use of top quality timber biomass as basic material, with extremely reduced ash web content, just regarding 3-5%.
Physicochemical indices of biomass molding fuel.
Density: 700-1300 kg/m3
Ash: 3-20%.
Moisture Web content: 15%.
Calorific Value: 3500-4500 kcal/ kg.
Burning Price: 96%.
Thermal Efficiency: 81%.
Smoke Blackness: <1.
Released Dirt Consistence: 80mg/m3.
The calorific value of biomass molding fuel obstructs differs with the type of basic materials. Take corn straw as an example: the calorific value is about 0.8-0.95 times that of coal, that is, 1.1 t of corn straw molding fuel amounts the calorific value of 1 t of coal. The burning efficiency of corn straw molding fuel is 1.3-1.5 times that of coal-fired central heating boiler, so the calorific effectiveness of 1 t of corn straw molding fuel amounts that of 1 t of coal.
Features of biomass molding fuel (BMF).
Biomass fuels can accomplish eco-zero emission of greenhouse gas carbon dioxide. The energy of BMF comes from the solar power fixed on plants by natural photosynthesis. Co2 released during burning originates from the absorption of all-natural carbon dioxide during its development.
Biomass fuel is a kind of low-carbon energy.diy feed pellet machineburning of BMF is generally unpredictable, and its fixed carbon web content is only about 15%, so it is a typical low-carbon fuel.
Lowering SO2 emission. BMF has much less sulfur than diesel, only 0.05%. Sulfur dioxide emission can be decreased without desulfurization gadget.
BMF ash web content is 1.8%, which is about 1/10 of coal-based fuel. A basic dust elimination tool can accomplish dust discharge requirements.
BMF has reduced nitrogen material as well as high oxygen material. It can properly decrease air demand as well as lower the development of nitrogen oxides when burning.
BMF is derived from farming and also forestry wastes, with an incineration price of 96%, and also the staying 4% ash can be recycled as potassium fertilizer, hence realizing a reliable cycle of "straw, fuel, plant food".
BMF has high density, tiny volume, strong developing, sealed packaging, secure and hassle-free transportation as well as storage.
The biomass molding fuel has the advantages of high volatility, easy rainfall, great carbon activity, flammability, much less ash, rapid ignition, more fuel saving and lower usage price.
