Auto Technology Turbocharges Biomass Generation

The BG25 CHP (Combined Heat and Power) unit generates 25 kW of power and recycles excess energy to save 212 tonnes of CO2 per year, says the UK-based firm.

“Our new turbocharged BG25 CHP generator uses readily available waste biomass in the form of wood chips or pellets to generate a consistent level of power, making it ideal for organizations in the wood working industry,” said managing director Paul Firth.

Hot air generated through a mile and a half of piping in a compact heat exchanger powers a Scania truck turbocharger. Heat energy is cycled back through the compressor to charge fresh incoming air and continue to drive the turbocharger.

Excess energy is captured by a second turbocharger that drives two alternators via a specially designed gearbox. The BG25 also provides local heating.

“The size of the CHP installation can power a hotel, large house, farm or modest industrial complex, but we are aiming to build units with significantly greater output, based on this technology. Nevertheless, we anticipate the market interest at this level will keep us pretty busy for the time being,” said Firth.

The new biomass generator was developed by Talbotts in conjunction with the bio-energy team at Harper Adams University College in Shropshire in the UK.
