Renewables

The Civil Engineering Team at Woonton Building Contractors have been involved with many Biomass and Biogas installations over the past 12 months. WBC have built up a significant amount of experience whilst undertaking these projects and have been involved in the design, structural calulation and construction of these projects, using best practices and materials.

Biogas installations

Below is a time-lapse video following the construction of the biogas installation Woonton Building Constractors and civil engineers carried out recently in Lincolnshire. This video is over a period of approximately 18 months. For scale, the large digester tanks are approx 20 metre diameter and the silage clamp shown at the rear of the site, is approx 2 acres. The tank compound is fully bunded and totally incased in concrete. Click here for additional information.

Construction of Biogas installation in Lincolnshire by Woonton Building Contractors, Herefordshire.

WBC are currently constructing another biogas installation in Herefordshire. We started on site in February this year and the project is progressing well. We have about a months work before it is completed. The large round digester tanks are approx 25m diameter and the silage clamp is 80m by 50m.

This plant will have the capacity to generate 500kW of electricity from maize, grass silage, and whole crop silage. The AD system will digest approximately 9,500 – 10,000 tonnes of feedstock per annum. This would equate to approximately 3,000 tonnes of broiler chicken manure and some 6,500 tonnes of farm crops.

Biomass (Wood Chip)

Woonton Building Contractors have been involved with many biomass installations which have required a dedicated steel frame building to store the woodchip and the bank of boilers. The woodchip is housed in a concrete bunker, usually wood ply lined, with a central paddle system and agitator to transport the material with a screw conveyor to the boiler. The buildings usually have a mixture of precast concrete and mass concrete wall panels to contain the wood chip and also provide independent bays to house the bank of boilers.

 

The use of biomass in heating systems is beneficial because it uses agricultural, forest, urban and industrial residues and waste to produce heat and electricity with less effect on the environment than fossil fuels.
