Goonhilly Earth Station
315Kw wood pellet heating system
Goonhilly Earth Station in Cornwall is a space science centre, famous for its satellite communication, space educational resources and community engagement activities. The earth station sought t0 enhance its green credentials and reduce energy costs by switching from oil to biomass heating for their main building.
The main building is 3,500m2 in size, with an annual heat demand of approximately 420,000kWh.
Fuel supply and chip handling
In order to avoid additional construction costs and disruption, Dunster built a unique, containerised pellet store off-site, which was then easily installed. The steel store has been completely insulated and then finished internally with phenolic ply, helping to ensure the free flow of pellet. Being long and narrow we installed three pellet injection connections to ensure that maximum capacity can be used. Wood pellet is being purchased from a local supplier.
System design and installation
As mentioned, Dunster designed the biomass system and fuel store to fit within new ISO containers; this was built to match the original construction, with an added twist of colour to brighten up the site. The system was designed to take on 100% of the heat load for the main building. Three P4, 105kW boilers were installed in cascade with a 6,500Ltr Galu accumulator tank, providing excellent modulation and built-in backup.
The Fröling control system has been connected to the internet to enable remote monitoring and access, meaning even the most remote locations such as this one are visible at the touch of a button.
Compared to their previous oil heating system, the biomass scheme is much more efficient and has provided a cleaner, greener source of heating.
Biomass heating at Goonhilly Earth Station has allowed the organisation to reduce energy costs and CO₂ emissions.
