B&W Clean Power Production Case Studies

WTE Boiler Upgrade With Water-Cooled Air Zones – Shetland Islands

B&W Renewable Service provided upgrade design, engineering and components for an energy from waste boiler which included new Inconel®-cladded water-cooled wear zones, air-cooling system, secondary air system, new feeding hopper, and combustion control system.

WTE Boiler and Furnace Upgrades - Eeklo, Belgium

B&W Renewable Service provided engineering, manufacturing, delivery, construction advisory services, commissioning, testing, operator training, and project management for new feeding systems, grates, riddlings and slag handling systems, water-cooled furnaces, combustion air system, support burners and hydraulic system for the plant’s two identical WtE lines.

Replacement of Economizers 1, 2, 3, and 4 - Odense, Denmark

B&W Renewable Service dismantled old and installed, tested and commissioned four new economizers on a waste-to-energy line at Fjernvarme Fyn.

Economizer Replacement, Line 3 - Högdalen, Sweden

Babcock & Wilcox Renewable Service provided detail design, engineering, procurement, manufacturing and replacement of the existing economizer at Högdalen waste-to-energy boiler in Stockholm, Sweden.

Panel Wall Replacement, Line 4 - Gärstad, Sweden

Babcock & Wilcox Renewable Service replaced the panel walls at Gärstadverket P4, Sweden. Scope of delivery included project management, engineering, design, purchasing, manufacturing, delivery, disassembly, assembly/installation, testing, commissioning, trial run and documentation. The scope of work was a comprehensive replacement of the boiler panel walls.

Furnace / Boiler Upgrade - Leirvik, Faroe Islands

Babcock & Wilcox Renewable Service upgraded the furnace and replaced the hot water boiler at Leirvik waste-to-energy plant in the Faroe Islands. The plant dates back to 1989 and was originally designed for 2.5 tons of waste per hour. The purpose of the plant upgrade was partly to increase the capacity of the plant and to extend the service life. The capacity was raised to 3.5 t/h, 12 bar and 140 °C and is expected to extend its useful life.

Panel Walls and Economizer Replacement - Uppsala, Sweden

The B&W Renewable Service delivery included project management, engineering, procurement, manufacturing and replacement of an economizer for a waste-to-energy boiler (Line 1) in Uppsala, Sweden. Also included in the project was to replace panel walls including cladding with Inconel® 625 on site.

Slag Conveyor - Holstebro, Denmark

B&W Renewable Service scope of supply for this project included project management, engineering, manufacturing, delivery, disassembly, installation, commissioning, testing and documentation for the replacement of the wet slag conveyor and grate siftings conveyor on both boiler lines 1 and 2 for the MEC waste-to-energy plant.

Onsite Inconel® Cladding and Combustion Air Upgrade - Sundsvall Energi AB

B&W Renewable Service won this project for onsite Inconel® cladding and combustion air upgrade at Korstaverket in Sundsvall, Sweden. The client also requested the possibility to increase the capacity of the boiler. We also performed a computational fluid dynamics (CFD) model and recalculated all boiler parameters.

Economizer and Boiler Wall Replacement - Karlskoga, Sweden

For this project, B&W Renewable Service replaced the front boiler wall and economizers 1 and 2, as well as installed a new rapping device system for cleaning of the heating surface on a waste-to-energy plant (Line 1) in Karlskoga, Sweden. Delivery included project management, construction, design, manufacture, delivery, dismantling, installation, commissioning, testing and documentation.

Onsite Inconel® Cladding - Linköping, Sweden

B&W Renewable Service scope of supply for this project included project management, engineering, design, purchasing, construction and documentation for onsite Inconel® cladding at boiler panel walls on an existing waste wood-fired boiler (Line 3) in Linköping, Sweden. The cladding was performed in the bottom portion of the first pass, including part of the rear, left, right and front walls.

AffaldPlus, line 4 - Næstved, Denmark

The DynaGrate® combustion system is the result of more than 40 years of development. The air-cooled grate is ideal for the incineration of both domestic and industrial waste because of the high efficiency combustion, excellent utilization of energy and good bottom ash quality.
