Project description
In December 2018 Babcock & Wilcox Renewable Service won an order for the replacement of 4 economizers on a waste-to-energy line (Line 13) at Fjernvarme Fyn.
Scope of delivery included project management, design, engineering, procurement, manufacturing, delivery, dismantling of the existing
economizers, installation, testing, commissioning and documentation. A different material was selected for economizer 1 due to corrosion problems, but apart from that, the economizers were replaced one-toone with same geometry and heating surfaces. A new feedwater shunt pump was included to provide a higher inlet temperature by mixing of cold and hot feedwater.
Tube Material for Economizer 1:
Ø33.7 x 3.6 mm, ASTM213/TP347HFG
Tube Material for Economizers 2, 3, and 4:
Ø38.0 x 4.0 mm, St. 35.8 /15 Mo3 – III DIN 17175
Scope of supply
- New economizers 1, 2, 3 and 4
- Shunt pump system, including valves and instrumentation
- Thermal insulation and cladding
- Necessary scaffolding and crane assistance
- Opening and closing of the boiler roof
- Delivery of basic spare parts
- Cleaning and blasting of components
- NDT
