Our customer a major UK based producer of Biomass Boilers for local government buildings and schools have asked us to provide a containerised Boiler House and integrated wood chip store of 60m3.
The project consists of 3 x 20′ containers. The first unit houses the actual Biomass Boiler. It has now been delivered to the customer for the installation of the boiler unit. The remaining 2 units (currently under production) will be joined together form the Fuel Store. The fuel is waste wood in either wooden pellet or wood chip form. The fuel is then fed from the Fuel Store into the Boiler Room via augers which connect through aperatures in the container walls. The process which is computer controlled ensures just the right amount of fuel is fed into the boiler to enable efficient heating with minimum amount of emissions. Hot water and heating is then linked to the existing distribution systems. The annual need is 400 tonnes of wood, which is hoped to save 165 carbon tonnes per year.
The Boiler House is manufactured from a new 20 foot long high cube container (9 feet 6 inches high) has additional double doors added to 1 side for access, which have in turn been fitted large louvered vents. These doors allow access for servicing the boiler once on site as well as ventilation.
To enable the wood chip to be delivered efficiently using an tipper lorry, we have incorporated our sliding roof deign into the Fuel Store. A 10 foot section of the container roof is mounted on rollers to allow it to be slid aside. Once the wood chip has been tipped directly from the delivery lorry into the Fuel Store the roof section is simply slid back and locked into place. As the fuel needs to be maintained in a dry condition the sliding roof is designed to remain watertight. The Fuel Store is also lined with marine ply, with a removable section adjacent to the original container doors allowing access for maintenance of the augers and stirrer.
Housing the Boiler installation in a containerised unit means a significant saving in cost over a more traditional building in terms of production time, ground works, and production time.
