How a Biomass Combustion Energy Plant Works
Biomass is a renewable fuel and is considered CO2-neutral. Our biomass technology helps to protect the earth and atmosphere from greenhouse gas emissions. What distinguishes biomass as a fuel type is that it was “recently alive.” Burning biomass is CO2-neutral in the sense that when it burns, it only releases the quantity of CO2 that the plant absorbed during growth.
Biomass can be derived from a variety of sources, and it’s essential to understand the properties and chemical composition of each one. Some biomass needs pre-treatment before the fuel is fed onto a combustion grate where it is burned. Fuels include:
In general, biomass fuels are evaluated on the basis of their physical properties (density, size distribution, humidity, foreign matter) and chemical properties (calorific value, proximate analyses, ultimate analyses, ash analyses, and ash-melting behavior).
The heat from the combustion is used to fire the boiler, which in turn generates hot water or steam. The steam turns a turbine that produces electricity. Today we can recover energy from biomass in highly efficient energy plants – generating heat, process steam, electricity, syngas, and/or bio-oil. Many of our biomass energy solutions are combined heat and power (CHP).
Readily available renewable energy with environmental benefits.
Biomass is a renewable, carbon-neutral, cost-effective and reliable fuel. Learn more about wood chips, wheat straw, bagasse and B&W's experience with a wide range of other unique fuels and environmentally sound technologies to ensure reliable and efficient energy utilization.
Technologies for the widely differing characteristics of opportunity fuels
Tomorrow's energy plants need to be ultra-flexible and our multi-fuel technology gives you the best flexibility and high thermal efficiency for your business case.
Service and Support
Our specialists provide a wide range of services, improvements and upgrades to maximize the useful lifetime of a waste-to-energy, biomass, multi-fuel or fossil fuel-fired plant.
PROJECTS & CASES
B&W Vølund supplied the ultra-supercritical straw-fired boiler, featuring an advanced straw feeding system for this revolutionary combined heat and power (CHP) plant in Denmark. The boiler is designed for 100 percent straw firing (approximately 150,000 tons per year), and is the world’s largest and most effective straw-fired boiler with ultra-supercritical steam parameters.
Babcock & Wilcox Vølund supplied the multi biofuel boiler for Strängnäs Energi AB. The energy produced by the boiler is to be used for high-efficiency electricity production, process steam for neighbouring industries and district heat heating for the town of Strängnäs. In order to benefit from green certificates for the initial 10 years’ operation of the plant, virgin wood (GROT) and waste wood chips are intended as the main fuel. The plant has also been designed to burn refuse-derived fuel (RDF) based on wood, paper and plastic and a fraction of peat.
