Design Concept for Schack® Convection Banks

	ALSTOM Power Energy Recovery GmbH’s design concept has been developed and optimized since 1960: Tubes welded to horizontal headers Tubes can freely expand downward No tube sheets, only baffle and guiding plates Small tubes < 2” are used Maximum prefabrication extent Modular Design: Tube bundles are delivered already installed in a refractory lined casing

Schack® Convection Banks are of Modular Design

• Critical welds are manufactured at original workshop
• All tests including, hydrostatic tests are performed before delivery
• Refractory work at workshop, no scaffolding on site
• Optimized fit of coils to casing, no interface problems on site
• Low erection time and costs
