Casey Industrial has been contracted to remove and replace existing scrubber booster fans (SBF) with four new Howden VARIAX Induced Draught Fans. SBF replacement work included auxiliary lube oil and seal air systems, insulation of SBF components, and start-up services. The SBF replacement was necessary to support SCR upgrades at Unit 2, a 430 MW coal-fired power station. Balance-of-Plant work included a SCR fire protection system (design, supply, installation, and start-up services), installation of multiple piping systems with heat tracing, an ash handling system, compressor equipment, ammonia storage equipment, ammonia sun shade steel structure, and service water booster pump skids.
