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
// 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
// Wastewater treatment
Combined Heat and Power
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.

What Our Customers Are Saying
Power+ Generator as a CHP Solution
From generating clean electricity and offsetting grid costs to drying biomass for profit and providing a district heating solution for the complex…
“The addition of the Power+ Generator to the Garden Centre increases overall site efficiency, reduces our use of fossil fuels and their ever increasing costs, ORC technology is critical to maximizing the site’s operations, and ElectraTherm is the most proven, robust ORC technology available.”
– Sam Ainscow, Summerseat & Bradley Ford Garden Centre
Taking Advantage of Wood Waste
Integrated Biomass Resources (IBR) teams up with Wallowa Resources Community Solutions, Inc. (WRCSI) to commission two Power+ Generators at a wood products mill in Oregon…
“The Power+ was easy to incorporate into our system and the installation and commissioning process went smoothly. The added electrical generation capacity allows IBR to offset a greater portion of the electrical demand at the mill, which displaces the retail cost of power.”
– Matt King, WRCSI
