The container-packed biomass CHP-plant produces, for example, enough electricity and heat for the annual needs of a farm or an entire small housing estate.

CHP - three main stages:

Gasification of dry wood chips. Gasification reactor is fully automatic and it generates tar-free SynGas.

Gas purification and cleaning. All mineral dust particles are removed by fabric filter. Heat is recovered by heat exchangers and can be used for heation.

CHP unit. Wood gas is fed to a combustion engine. Heat is collected from engine cooling fluid and exhaust fumes. The engine runs a generator that produces clean domestic green electricity. Frequency can be 50 or 60 Hz. Electric power is 28 kW or 40 kW (netto).

Fuel feding and gasification

• Fuel is fed from the siloor larger biomassstorage by screw and chain conveyors

• Rotating feeder preventsfrom free air flow to thereactor. It also protectsfrom back fire

• Fuel is fed from the siloby screw and chain conveyors

Gas cooling and filtering

1. Cooling before the filtering phase (heat recovering)2. Dry filtering system (3. Washing the gas (for dust particles)4. Cooling to the final product gas temperature (heat recovering) 5. Cooled and filtered gas to the motor

“I have done gasification research and development at VTT since 1981, Volter´s gasifier is the first ideal working downdraft gasifier that I have come across. Congratulations!

1 x Volter 30 kWe1x Volter 40 kWe (will be installed in February 2014)

Page 25: Volter CHP biomass heat and power Cogeneration

The project at Quarry Farm is situated just outside of Stamford. The main concept of this project was to create a wood supply chain for the local area that is in the right specification for gasification. We are going about this by installing a 30 KWe unit (as seen in picture) and also a second 40 kWe unit will be installed in February. Both of these units combined will generate 165Kwth which will be dispersed into a drying floor to dry the woodchip to the required moisture content. As the unit is a combined heat and power generator, as the power is produced we will either be using the it onsite or selling it back through the grid. One of the major benefits for this technology is the revenue stream that it unlocks through government incentives these come through RHI (Renewable Heat Incentive) and ROCS (Renewable Obligation Certificate).
