Combined Heat & Power (CHP)

Furnace 1

The most recent addition to our Eco Park is the Combined Heat & Power Plant (CHP) at our Parley facility in Dorset.

The new plant is capable of burning 10,000 tonnes of oversized organic material which is taken from the established composting process on site.

The energy generated from the plant will be used to power the site, with any excess fed into the National Grid.

Our Process

Our Biomass CHP plant converts waste wood derived fuel into heat and power through a combustion process.

1. The process starts in the loading area where plates move back and forth (powered by hydraulic rams) to pull the wood fuel into the conveyor system.


2. At the top of the conveyor belt, the material drops into the feeder. Two cork screw mechanisms push the material forward from the feeder and into the furnace.     


3. Within the furnace, the material tumbles down the grate, burning as it goes. 


4. The gasses released from the combustion process rise to the top of the furnace and out through a controlled channel. At the same time, the ash from the material passes through the bottom of the furnace and drops onto a conveyor, which moves it out. 


5. The hot gasses travel through a large heat exchanger where it is passed up and down three times to extract as much heat from the gas, into the oil pipes.  


6. The hot oil then passes through an Organic Rankin Cycle (ORC) system which vaporises to turn a turbine and generate power.


7. The hot gasses then come out of the heat exchanger into the flue gas filtration system which is constantly monitored to ensure adherence to strict emission standards.


End Results

The CHP plant generates clean, green, renewable energy which is used to power equipment on site which, for years, had been run from fossil fuels.

The heat is also harnessed and used on site to help with processing organic wastes.

Additional Info


Biomass CHP Fact 1

The combustion gases must reach and maintain temperature above 900°C for 2 seconds - That's as hot as the surface temperature of the planet Venus!

Biomass CHP Fact 2

The thermal oil flows at a temperature of 315 degrees at its hottest!

Biomass CHP Fact 3

The 750kW of electricity produced is enough to power over 100homes a year!



Facts & Data

The Organic Rankine Cycle (ORC) is named for its use of an organic, high molecular mass fluid with a liquid-vapor phase change, or boiling point, occurring at a lower temperature than the thermal oil-steam phase change.
