Biomass Systems

Biomass Heat Recovery

Biomass is one of Earth’s most abundant organic sources of energy. Boilers have been used for over a century to dispose of vegetable waste and wood by-products while providing usable thermal for heating and power applications. Boilers are also extensively used alongside anaerobic digestors in the production of biogas – providing heating solutions to the site. However during these processes a substantial amount of energy is lost as waste heat.

By utilizing ElectraTherm’s Organic Rankine Cycle (ORC) heat to power system, the heat produced from these boilers can be further utilized to generate emission-free power that can be used to offset grid costs or sold back to utility, provide district heating as a CHP unit, or even eliminate flaring at biogas applications.

Typical Fuel Sources

Typical Applications

//  Sawmill residues

//  Forestry by-products (hog fuel)

//  Wood chips, pellets

//  Various wood waste

//  Animal waste

//  Food waste (husks, shells, etc.)

//  Agricultural waste

//  Sewage sludge

//  Combined heat and power

//  District heating

//  Sawmills, wood products

//  Biomass plants

//  Biogas plants

//  Agriculture

//  Landfills

//  Wastewater treatment

Combined Heat and Power

By incorporating a Power+ Generator or Active Cooler into your existing boiler system you can further take advantage of the heat produced to generate power as well as usable thermal.

The benefit boiler applications have is that most of the equipment needed for our system is already in place (i.e. the boiler), which offsets costs and improves your return on investment. Additionally, by simply producing more hot water you are able to maximize the output of the ORC system.

Combined Heat and Power

Quincy, California – A Power+ Generator will see extended use as a biomass CHP unit to heat a local 53,000 square foot health services building while generating additional electricity and supporting forest restoration of the surrounding landscape.

The boiler used to fuel the Power+ Generator is modeled to consume 200-300 tons of woody biomass (hog fuel) a year – disposing of a considerable amount of undergrowth in this fire-prone landscape. The CEC estimates annual savings over $42,000 from the increased heating efficiency alone before the offset grid supply is taken into account.
