Hitachi Zosen Inova from Zurich relies on STAG technologies for their new WtE plant Rookery in England.

For the two boiler lines STAG plans and delivers the mechanical and pneumatic boiler ash removal system, using STAG impact mills to prepare the boiler ash for pneumatic conveying. The proven STAG rotary valves MVP and DVP are used for pneumatic conveying. For flue gas cleaning and recirculation, hydrated lime and activated carbon powder are used. Lime hydrate is fed by volumetric metering and PAC by four gravimetric feeders to the subsequent pneumatic dilute phase conveying system.
