Glen Avon Growers

Flexible system – for both straw and wood chips

In 2016 our British partner, Manco Energy, delivered two Linka biomass plants for Glen Avon Growers.

With two new systems, the English vegetable producer can heat up their glasshouses with cheap, CO2 neutral biofuel.

Background

Glen Avon Growers is a large producer of tomatoes and cucumbers based in the eastern part of England near Hull. The plants are grown in 42,000 m2 glasshouses, where a constant temperature is needed.

Due to the British Renewable Heat Incentive (RHI) Glen Avon decided to switch to using biomass as primary fuel.

Earlier the vegetable grower used gas as fuel, but by switching to biomass they are able so reduce heating costs, as biomass is significantly cheaper.

Manco Energy delivered two biomass plants for Glen Avon, a straw plant and a wood chips plant. The heat from the plants is used for heating up their glasshouses at two different sites.

The solution

The straw plant at Glen Avon consists of a Linka straw shredder installed with a 12 meter conveyor.  Particularly for this plant is the addition of a rubber belt and heightened sides on the conveyor. This way, the conveyor can be filled with wood chips (or other granulated fuel) as a supplement to straw.

The 995 kW Linka H boiler has a built-in step grate. Along with Linka’s patented combustion technology this ensures optimal use of the fuel. The ash is automatically transported outside the plant to a nearby ash pit. Due to its size, the pit can hold a large amount of ash and only needs to be emptied 1-3 times a year.

The straw system is also equipped with a bag filter, which cleans the flue gas and hereby reduces dust emissions.

A second plant was delivered for Glen Avon in the autumn of 2016. This too is a fully automated system with a 995 kW for wood chips. The plant is equipped with a PLC control system that monitors the plant and sends out alarms via internet and SMS.

The wood chips are stored on a 40 m2 walking floor. The fuel is automatically transported via augers to the boiler. The second boiler is also constructed with a step grate and Linka’s patented combustion technology, as well as automated ash transport to the separate ash container.
