Biomass Power Plant
Widnes,
Great Britain
The task
At the Widnes location in the United Kingdom the construction of a new biomass-fired power plant was planned. The power plant is part of the Stobart Park project for the extension of a transhipment terminal and is meant to supply all of the facilities with heat in the future and to additionally feed electricity into the public grid. Standardkessel Baumgarte was selected as the technology supplier in advance because of its technical know-how.
The solution
The plant is being constructed with the already frequently tried and proven Standardkessel Baumgarte firings system and boiler concept that is specially designed for the combustion of waste wood. The generously dimensioned furnace of the 4-pass boiler concept, as well as, the radiation pass arranged downstream ensure excellent burnout of the flue gases. The downstream convective passes house the heating surfaces of the superheaters, evaporators and economisers. The grate firing system is supplied with combustion air via separate primary air/secondary air systems. The primary air is fed in below the grate, the secondary air above the grate via secondary air nozzles systematically to combustion.
