PERFORMANCE REPORT™

This performance report was prepared for the diagnosing of and preventing problems that cause you to experience low performance or baghouse failure.

We also offer a more in-depth DETAIL-PERFORMANCE REPORT which requires input from the customer. (This helps in pin-pointing the problem.)

The following performance report is normally done on all of the bags that you have sent in. This report covers all conventional baghouse and processing collector. All bags that are returned to you have been tested and are 100% reconditioned (unless stated otherwise). If a bag has failed we will correct the damaged area free of charge for minor repairs. If the bag is not repairable we will reject the bag.

GLOSSARY OF TERMS

  • BAFFLES

  • A device consisting of a plate or a series of plates which evenly distributes airflow and dust within a dust collector, to protect filter bags from direct impingement of dust which will damage bag filters.
  • BLEED-THROUGH

  • Particulate migration through the bag filter fabric.
  • BLINDING

  • Fabric blockage by dust or fume, or liquid not being discharged by the cleaning mechanism, resulting in an increased pressure drop across the media and decreased air flow.
  • BLOWPIPE

  • Used to direct the air down through the venturi during cleaning and should always be considered an integral component when troubleshooting a baghouse. Blowpipe misalignment and deterioration due to improper holes alignment and ineffective mounting, always look for plugged or partially plugged holes.
  • CUSTOMER INPUT

  • The more input from our customer the more beneficial the reports will be.
  • DETAIL PERFORMANCE REPORT

  • This report is to help pinpoint problems or low performance in your baghouse. This requires input from our customers before the bags are taken out of the baghouse. You will need to fill out a bag failure chart as you are changing out the bags and answer some questions.
  • DUST CAKE

  • Desired dust buildup on the fabric to filter incoming gases and keep particulate on fabric surface.
  • FAILURE

  • If the bags have failed our testing, the bags were not performing to new bag specifications.
  • GRAIN LOADING

  • The amount of particulate by weight in a given volume of air.
  • PERFORMANCE REPORT

  • This report will give an overview of problems or low performance in your baghouse. For a more detailed analysis see DETAIL PERFORMANCE REPORT.
  • REJECTS

  • The bag is not to be put in the baghouse and the bags will be disposed of at our facility. * If rejects exceed 50% of the entire order there will be a charge for the handling of the disposal.
  • STEREOPTIC VIDEO ANALYZER

  • Frisbie's Filter Service, Inc. lab testing machine which can perform over 100 performance tests on your baghouse system.
  • TECHNICAL DATA REPORT

  • Our report tells the condition of bag filters. According to O.E.M. specifications. This insures you that reconditioned bags will perform just like new. This report has already been done on your bags as a standard procedure here at Frisbie's Filter Service, Inc.
  • WEIGHT DIFFERENTIAL

  • The amount of grain-loading on the surface of the fabric at any given time.

AREA 2. BAG FAILURE DUE TO OUTSIDE SOURCE
2A. SUBSTANCE & MATTER ENVIRONMENTAL FAILURE - 194 failed
2B. STRUCTURAL FAILURE - none failed

PROBLEM AREA
COMMON OCCURRENCE (HIGH RESTRICTIONS) (DAMAGED BAGS) (LEAKAGE) SUBSTANCE, MATTER, ENVIRONMENTAL AND STRUCTURE TESTING. THIS TEST DEALS WITH OBJECTS AND THE STRUCTURE THAT DESTROY AND GIVE YOU UNNECESSARY WEAR ON YOUR BAGS. THESE DAMAGE BAG FILTERS FROM THE OUT SIDE OF YOUR BAGS. THIS IS DIRT SIDE OF THE BAGHOUSE. THIS WILL NORMALLY MAKE UP 50% OF THE FAILURES WE SEE AND TEST FOR, SUBSTANCE & MATTER TEST WE PERFORM ARE THERMAL, MOISTURE, GRAIN LOADING, WEIGHT DIFFERENTIAL, CHEMICAL, AIRFLOW, DUST-CAKE AND GASES. STRUCTURE FAILURE INDICATES HOUSING PROBLEMS, DEFECTIVE PARTS AND TUBE SHEETS THAT ARE WEARING OUT YOUR BAGS.

SOLUTION
FOR SUBSTANCE, MATTER, ENVIRONMENTAL AND STRUCTURE FAILURE, CHECK FOR THESE FOLLOWING PROBLEMS:
EXCESSIVE HEAT IN BAGHOUSE, MOISTURE ENTERING BAGHOUSE, PRODUCT FILLING HOPPER, BROKEN AUGER SYSTEM, PRODUCT ENTER BAGHOUSE AND HITTING THE BAGS DIRECTLY, CHEMICAL ENTERING BAGHOUSE, AIRFLOW SUCH AS BLOWER PIPE FAILURE. WORN OR NO BAFFLES AND EXCESSIVE GASES IN AIR STREAM, HIGH ALSO FOR GRAIN LOADING STRUCTURE CHECK FOR RUSTED TUBE SHEETS, DEFECTIVE PARTS, AND PIPING THAT HAS BROKEN OR LOST HOUSING PARTS.

RESULTS
THE PAY OFF CAN BE VERY LARGE, IF YOU TAKE TIME TO SOLVE THESE SORT OF FAILURES; STRUCTURAL, SUBSTANCE AND MATTER. ALSO IN SOME CASES WE HAVE FOUND THAT SWITCHING THE TYPES OF BAGS YOU ARE USING OR GOING TO A DIFFERENT FINISH ON YOUR BAGS CAN REDUCE SOME EFFECTS ON YOUR BAGS. IN ORDER FOR US TO HELP ISOLATE THE EXACT CAUSES OF THE PROBLEM WE WILL NEED TO PERFORM A DETAILED PERFORMANCE REPORT. TO HELP US WITH THIS REPORT WE WILL NEED MORE INPUT FROM YOU. FRISBIE'S FILTERS LAB CAN PERFORM THIS TEST FOR YOU AT NO CHARGE.

AREA 5. FAILURE ON REMOVAL
5A. DEGRADATION FAILURE - 1 FAILED
5B. ENGINEERED FAILURE
5C. SUBSTANCE, MATTER, ENVIRONMENTAL

PROBLEM AREA - COMMON OCCURRENCE (REMOVAL FAILURE)
DAMAGES DURING REMOVAL WILL INCREASE YOUR BAG FILTER COST AND MAY DAMAGE CAGES. IF THE BAGS ARE DAMAGED TOO BAD, WE WILL NOT BE ABLE TO RECONDITION THEM AND THEY WILL HAVE TO BE REPLACED. IF YOUR PERSONNEL ARE DAMAGING BAGS ON REMOVAL, THEY COULD ALSO BE DAMAGING THEM ON INSTALLATION. THIS IS NORMALLY A TRAINING PROBLEM, BUT NOT IN ALL CASES. THERE MAY UNDERLINING PROBLEMS WHY YOUR BAGS ARE NOT COMING OFF; THERMAL FAILURE, ENGINEERED FAILURE, WORN OUT PARTS, ETC.

SOLUTION
TRAINING YOUR PEOPLE ON THE REMOVAL OF BAG FILTERS. PROBING INTO WHY THEY DID NOT COME OFF YOUR BAGHOUSE PROPERLY. FIXING OR FINDING OUT WHY COULD INCREASE YOUR OVERALL PERFORMANCE AND SAVE YOU MONEY IN THE LONG RUN.

RESULTS
WHEN BAGS WILL NOT COME OFF YOUR CAGES OR OUT OF YOUR BAGHOUSE PROPERLY OR IN A TIMELY MANNER, THIS WILL GREATLY INCREASE YOUR LABOR COST. WE STRONGLY RECOMMEND YOU TO TAKE THE TIME TO SEE WHY THIS PROBLEM IS OCCURRING. WE CAN HELP YOU DO THAT, WITH OUR PERFORMANCE REPORT, PREFORMING TEST AND OUR STEREOPTIC VIDEO ANALYZER
