Reduced baghouse maintenance with LPHV pulse cleaning technology

More than thirty years ago, the industrial gas cleaning industry began to explore low-pressure-pulse cleaning filtration as a means to improve baghouse installations in various process industries from the standpoint of simplicity, maintenance, and safety. “Low-Pressure High-Volume” cleaning pulse has come to be referred to as LPHV pulse-jet baghouse technology. Early introductions were in the metallurgical and power industries beginning in the late-seventies and early-eighties. By the second-half of the nineties, LPHV baghouses were being installed on cement kilns and clinker coolers. And by 2005 cement kiln ESPs were being converted to LPHV pulse-jet baghouses. Lower maintenance and operating costs have been significant factors in selection of this technology approach. Details of operation and maintenance with LPHV pulse cleaning are presented in this paper.
