Biomass Energy

Steam, Hot Water, and Air Systems

Biomass Energy Solutions use biofuels that provide clean, sustainable, and renewable energy for organizations. Organizations looking for sustainable development are using biomass energy systems to increase energy output, reduce emissions and decreasing energy costs. AFS is committed to creating a custom strategy using biomass & renewable energy technologies to meet your individual energy needs.


AFS Energy has designed, fabricated, and installed over 125 biomass energy systems in the US & Canada. In all, these systems are burning over 1,500,000 tons of renewable fuel yearly which produces over 50,000 bhp & 1,828,600,000 btu/hr. Biomass can be such an efficient and reliable solution that our clients often experience a payback of 2 to 3 years on their systems.



AFS Energy Systems has been in renewable and sustainable energy industry since 1990. Between the 3 founding members you will have access to over 120 years of combined engineering experience in the Biomass industry. 


Examples of biomass fuels are agricultural biomass, sawdust, wood, bark, pellets, oat hulls, rice husk, chicken manure, nuts, shells, husks, paper, & card/board products.


Your labor requirement should be reduced with an AFS biomass energy system as our systems require very minimal human intervention. The AFS Total Control System uses state-of-the art computer, Primary Logic Controller (P.L.C.) and Variable Frequency Drive (V.F.D.) technology and logic to automatically control your energy system.


If an issue arises, the system automatically contacts your Operator so constant oversight isn’t necessarily required. Bottom line – the average system administrator spends 2-4 hours per week caring for the biomass system!

Automatic Ash Removal Furnace

An automated ash removal increases the efficiency of the boiler by removing ash from the boiler.  Ash removal is fully automatically from the space under the burner in the boiler by means of a screw conveyor which empties the ash regularly into an external ash container.

Pneumatic Injector Stoker System

Advanced stokers are reliable and efficient and are
used to fire a variety of fuels, including wood residue, municipal solid waste, and agricultural materials. Improvements have been made regarding firing systems, fuel distribution systems, furnace design, efficiency and reliability.

Overfed Stoker System

Overfeed stokers employs a moving grate assembly where the fuel is fed into a hopper and then onto a continuous grate that conveys the coal into the furnace. As it moves through the furnace, it passes over several air zones for staged burning.
