Green’s combines quality and speed for Birmingham biomass building

The biomass plant in Tyseley, just outside Birmingham, provides around 72,000 MWhr of renewable electricity to the national grid annually; enough power for around 18,500 households. Power is raised by using advanced technology to gasify waste wood, raise steam and drive a steam turbine unit.

EPC contractor and ongoing operation and maintenance provider for this project, MWH, chose Green’s to design, manufacture and install a plain tube economiser that would provide optimum efficiency and reliability. Access doors were also added to the new design to ensure easy inspection and manual cleaning of the tubes in the future.

Green’s proposal involved removing the tube sheets and all 1,296 tubes, which were some 8km in total length, and replacing them with 36 triple-coil economiser elements. The system design enabled much of the required welding to be completed in Green’s factory and the non-destructive testing to be carried out in their in-house testing facilities to make site operations as effective as possible.

Daniel Francis, operations and maintenance manager at MWH says: “We were extremely impressed by Green’s performance. They fabricated the system in ten weeks and, by working round the clock, installed it in just 12 days to ensure it was completed before the outage end date.”
