What is Biomass
Biomass—renewable energy from plants and animals. Biomass is organic material that comes from plants and animals, and it is a renewable source of energy. Biomass contains stored energy from the sun. Plants absorb the sun’s energy in a process called photosynthesis. When biomass is burned, the chemical energy in biomass is released as heat.
Examples of biomass and their uses for energy
- Wood and wood processing wastes—burned to heat buildings, to produce process heat in industry, and to generate electricity
- Agricultural crops and waste materials—burned as a fuel or converted to liquid biofuels
- Food, yard, and wood waste in garbage—burned to generate electricity in power plants or converted to biogas in landfills
- Animal manure and human sewage—converted to biogas, which can be burned as a fuel
Converting biomass to energy
Solid biomass, such as wood and garbage, can be burned directly to produce heat. Biomass can also be converted into a gas called biogas or into liquid biofuels such as ethanol and biodiesel. These fuels can then be burned for energy.
Biogas forms when paper, food scraps, and yard waste decompose in landfills, and it can be produced by processing sewage and animal manure in special vessels called digesters.
Ethanol is made from crops such as corn and sugar cane that are fermented to produce fuel ethanol for use in vehicles. Biodiesel is produced from vegetable oils and animal fats and can be used in vehicles and as heating oil.
How much biomass is used for fuel?
Biomass fuels provided about 5% of total primary energy use in the United States in 2017. Of that 5%, about 47% was from biofuels (mainly ethanol), 44% was from wood and wood-derived biomass, and 10% was from the biomass in municipal waste. (Sum of percentages is greater than 100% because of independent rounding) Researchers are trying to develop ways to use more biomass for fuel.
Features of Biomass Briquette Fuel
- Green energy, clean and environmental conservation: biomass briquette fuel is free of sulfur and phosphorus, smokeless and odorless, no sulfur and phosphorus release when burning, is a kind of green and environment friendly energy with so called good name of “green coal”.
- Low cost, high added value: high calorific value, long burning time, high stove temperature, free of sulfur, harmless to stove and boiler, so as to extending the life time for stove and boiler, the users will get more advantages thereon.
- High density, facilitating storage and transportation: featuring smaller sizes, high density, biomass fuel briquettes are easy to be stored, transported, and used consistently.
- High efficiency and energy saving, renewable material: high volatiles, less ash content, longer burning hoursd, less landfill, reducing discharging cost, but gaining profits by collecting quality organic potash fertilizers from recycled ash residues.
Application of Biomass Briquette Fuel
Biomass briquette fuel is used to offer steam and hot water for industries as textile, printing, paper, food, rubber, plastic, chemical, pharmacy, etc. and is able to be used for heating, air conditioning, and supplying hot water for people’s daily use. Also is widely used for generating electrical power.
Briquette feeds features
Briquette feeds, so called as animals’ popular favorite compressed cookies, having features as:
- high density (0.5-0.8g/cm3), 20-30 times higher than the original materials, extremely facilitating transportation and storage, stack up right after packing, advantageous to long distance transportation.
- Tasty to eat, 100% eaten up. Animals love to eat, due to the tasty burned smell of the feeds got by high temperature during production.
- Raw to “cooked”, good for digestion and assimilation
- High pressure and temperature, disinsection and sterilization, no additives, 100% green natural feeds, safe for feeding.
- Fire resistant, spoilage resistant, long term storage.
- Briquette sizing 32*32*20mm-80mm, meeting the animal’s fiber food demand, more rational.
- High adaptation to other feed materials, in wet or dry condition. Mostly convenient for large scale farms, isolated farms and places shortage of grass.
- Rich nutrition. There are corn, bean, groundnut straw, and alfalfa briquettes, etc available on the markets.
According to test results, the nutrition value of general corn straw is equivalent to that of north east china grass. Comparing to general straw, the cows will gain more weight of 15%, milk output will increase by 16.4%, saving raw feeding materials by 30%, overall cost will be decreased by 20%, by feeding briquetting feeds. It shows that the cows will gain more weight apparently of 24-39% by feeding briquetting feeds, comparing to fresh corn straws.
