Wall Colmonoy’s new ColWear Plates are reportedly well-suited for high-demand industrial fans due to their wear protection and resource and energy efficiencies. ColWear Plates are used in the manufacture and repair of industrial fans to avoid costly down time and replacement. ColWear Plates protect against the aggressive environments where industrial fans operate – a combination of abrasion, particle erosion, pitting/dusting corrosion, surface oxidation and intergranular corrosion at high temperatures – to achieve a longer lifetime in service.
Intense abrasion is a significant issue, especially in coal-fired plants, when particles in the airstream cause the wearing away of the fan surface by friction. This is particularly problematic in the fan blades and scroll housing.
ColWear Plates are lighter and more uniform than traditional wear-resistant construction materials. This can make the fan far more energy efficient and more balanced, particularly important for the impellers, as it reduces the amount of adjustment required. This can reduce energy expenditure, costs, maintenance and downtime.
ColWear Plates are manufactured with both mild and stainless-steel base materials and higher-grade nickel alloys. The materials allow the plates to withstand higher temperatures and higher rotational speeds, so that fan performance is enhanced.
