A Baghouse Maintenance Success Story: High Efficiency Filter Bag Cleaning
Ever wondered what the Albarrie Filtration advantage is? Learn more about our services and process by reading the case study below.
The Customer
A southern-US coal and local petroleum coke-regulated electricity/utility company.
The Baghouse Unit
Two train dust collector baghouse unit with 12 compartments. Each train with 9,760 filter bags totalling 19,520 bags. Each filter bag was 26’ L x 6” dia made of PPS Membrane filtration fabric. Each train is 1.2 Million ACFM.
The Customer’s Problem
The power plant was experiencing an increase in delta pressure. This was causing power production losses due to an upset in the control of the NOx emissions.
The company thought the only solution to alleviate this problem was to replace all 19,520 PPS Membrane filter bags and cages — a $6-million capital expenditure.
The Albarrie Solution: High Efficiency Filter Bag Cleaning
A before and after look at the power of Albarrie's high efficiency filter bag cleaning process.
Upon discovering the predicament, Albarrie presented the customer with a solution — a High Efficiency Filter Bag Cleaning Service.
The customer was asked to send several filter bags to the Albarrie Laboratory for testing and evaluation. In an isolated chamber test, it was determined that the recovery level of the filter bags was achievable; the heavy dust cake was able to be removed using Albarrie’s High Efficiency Filter Bag Cleaning Equipment and flow recovery reading returned to positive values.
The customer decided to proceed with Albarrie’s recommendation and instead of replacing all 19,520 filter bags, Albarrie’s “in situ” HEC service was performed.
How Albarrie Achieved Filter Bag Success
• Examination of the current condition of filters bags and cages was conducted. Flow testing was performed inside the baghouse, and results reaffirmed initial chamber test’s positive results.
• All pulse pipes were removed.
• Albarrie’s highly experienced field technicians proceeded to clean all 19,520 filter bags, one by one, using AES’s proprietary HEC equipment.
• Once cleaning was completed, a leak detection test was performed to determine if any bags were faulty, any broken bags found were replaced.
• Additional services included vacuuming of all tube sheets using a vac truck, plus any minor repairs required to blow pipes and bolt down studs.
The Results
• Albarrie’s High Efficiency Filter Bag Cleaning Service postponed the customer’s need to spend $6-million on the purchase of 19,520 new PPS membrane filter bags and cages.
• After start up, power production returned to full capacity/load.
• Delta pressure decreased from 15” to 7”.
• Opacity returned to 2% (normal levels).
• The customer experienced increased permeability within the dust collector system.
