BARRETT BURSTON MALTING KILN MODIFICATION PROJECT

Barrett Burston Malting is a major supplier of malt to Australia’s domestic and international brewing industry.

The company’s upgrade converted the facility from existing low-efficiency, high-emission NOx burners to a modern system of NOx-free high-performance Varinox heaters and Glass Tube Heat Exchanger units supplied by the Swiss company Flucorrex.

This involved:

• Laser point cloud surveys of the existing site to accurately model the existing site and provide the basis for 3D models of the final structure and full fabrication drawings
• Fabrication of over 110 tonnes of structural steelwork, comprising large welded beams and multi-story access stairs and platforms spread across two kilns
• Fabrication of large, fully-sealed stainless-steel ducts to enable air processes on both kilns
• Installation of proprietary equipment including three large air heaters (5m (W) x 4m (H) x 8m (L)) and 44 packs of extremely delicate bundles of Glass Tube Heat Exchanger units at heights up to 25m
• Construction during production periods before a shutdown period of four days, where the new process was introduced
• Coordination of multiple trades, including electricians, plumbers, heater technicians, cladders, sheet metal workers, riggers, and crane operators.
