Case Study: Powerhouse Duct Conversion Hayes Mechanical installed new ductwork to reverse the flow of gases going through an existing electrostatic precipitator utilizing air chain hoists, trolleys, MODULIFT® modular spreader beams and rigging supplied by Lifting Gear Hire. THE SITUATION In 2014, Hayes Mechanical was contracted by a Midwest power generation company to execute the “Hot to Cold Duct Conversion” project. The project involved changing the flow of gases going through the precipitator in order to reduce the operating temperatures, which would in turn allow the mercury emissions to be reduced. According to Bill Bluis, the Vice President of Industrial Construction at Hayes Mechanical, the boiler flu gas duct modification project required the removal of over 625 linear feet of exi
