July 10, 2003 — ALSTOM has recently been awarded a contract by Voestalpine Stahl GmbH., Austria, for a total contract value in excess of 18 million euros.
The contract covers the rehabilitation of an existing 135 tonnes/hour boiler and the design and supply of a new 135 tonnes/hour boiler with a peak load of 157 tonnes/hour. The boilers are for a steel mill located in Linz, Austria.
Both boilers will be mainly fuelled by blast furnace gas, a by-product of the steel mill. The boilers will provide steam to drive turbines for the fresh air fans. These fans will supply air to a blast furnace. The older rehabilitated boiler will remain as standby in order to ensure an extremely high availability of the steam generator plant.
ALSTOM’s scope of work also includes the integration of the system and the controls and instrumentation (C&I) for both units.
The project schedule is designed to minimise any downtime of the existing facility. To ensure this, the new boiler will be assembled outside the boiler house while operating the old unit and shifted to its place in a short outage of the steel plant. The plant will be ready for commercial operation in October 2004.
