Project Description

In 2020, Babcock & Wilcox Renewable Service won the project for an upgrade of a hot water boiler at Lerwick Energy Recovery Plant, including the installation of water-cooled wear zones.

The aging waste-to-energy plant was experiencing excessive slag accumulation on the furnace walls, resulting in loss of capacity and increased downtime to remove slag from the furnace.

Project Scope

The delivery included engineering, manufacturing, mechanical disassembly and assembly, electrical installation, programming, commissioning, testing, operator training and project management for new water-cooled wear zones with patented air-cooling system. A new secondary air system, a new feeding hopper and a combustion control system upgrade were also included in the delivery.

A computational fluid dynamics (CFD) analysis formed the basis for the design of the secondary air system and the water-cooled wear zones, while determining the expected temperature distribution. The CFD analysis also confirmed that the revamped waste-to-energy plant would meet the requirement for retention time during operation.
