STEEL BELT CONVEYORS FOR SEVERE CONDITIONS since 1929

STEAG State Power Inc.

THE CHALLENGE

On the northern coast of the island of Mindanao in the Philippines, the German IPP STEAG and a local partner developed a 2x116 MW bituminous coal-fired power plant. Kawasaki Heavy Industries (KHI), as general contractor, constructed both power plant blocks.
This power plant covers the growing energy needs of the  island of Mindanao and thus significantly contributes to the development of its infrastructure. The project challenge was to meet all local statutory environment requirements and the standards of the World Bank: including a dry bottom ash handling system with the aim to save water and improve the boiler efficiency.
The installation of the MAC® (Magaldi Ash Cooler) system for the bottom ash handling contributed to achieve those targets, especially in terms of water saving, reduction of ash pond space requirements and improvement of the boiler efficiency.

 

THE CUSTOMER

STEAG State Power Inc. (SPI) is a leader in advanced coal power generation technology. Its strengths are efficiency, reliability, safety, innovativeness and social responsibility. It was established in 1995 as a special-purpose company created to own, finance, construct, operate and maintain the first coal-fired power plant on the island of Mindanao. SPI is majority owned by Steag GmbH which is Germany’s 5th largest electricity producer and a pioneer of highly efficient generation technology using hard coal.

 

THE SOLUTION

Magaldi Power, together with KHI, designed a simple configuration of the MAC® with the use of a single steel belt conveyor able to ensure the high standards imposed by the End User in terms of reliability and safety during operations.
The MAC® dry bottom ash handling system is comprised of a mechanical seal, a transition chute and then the MAC® extractor. Downstream the MAC® there are a crusher, a double flap valve and a mixer unloader to discharge the bottom ash onto open trucks. With reference to the Mindanao project, STAEG was fully satisfied with this environmentally friendly and highly efficient dry ash removal system after their positive experiences with the Magaldi products installed at Termopaipa PP (1x165 MW) in Columbia and Iskenderun PP (2x605 MW) in Turkey.
