First whole log woody biomass power plant commissioned

Renewable energy company ElectraTherm, in partnership with Air Burners, is to develop a whole log wood waste burner utilising its Organic Rankine Cycle (ORC) power generating technology.

The product, called the PGFireBox, eliminates large amounts of wood waste without any pre-processing.

Air Burners, an air curtain burning system, utilises patented technology to dispose of vegetative waste without costly pre-processing requirements. The self-contained unit generates electricity from vegetative waste and is one of the fastest methods available today (6-8 tonnes per hour).

The PGFireBox is portable and can be deployed close to the location where the woody biomass is collected, applicable at sites such as landfills, forest maintenance, fire prevention, and natural disaster clean up.

ElectraTherm's Power + Generator feeds off the heat from the burner to generate up to 110kWe of fossil-fuel free electricity. Through the ORC process, hot water heats a working fluid into pressurised vapour. As the vapour expands, it drives ElectraTherm's patented twin screw power block, which spins an electric generator and produces power.
