Getting to the Root of the Problem
Today, CMS is the only company in the world that offers complete performance assessment, integrated corrosion assessment and repair services for tubular air preheaters. Our inspection and assessment programs provide an accurate and comprehensive picture of the entire air heater system, pinpointing all areas of tube damage and potential financial impacts.
Our experienced inspection specialists start the process using custom-designed tools to inspect your equipment and look for damage that affects your daily performance and sometimes leads to unscheduled downtime. In addition, we have developed a proprietary Air Leakage Calculator that uses your own operating data to determine precisely where your system performance is impacted and what you are losing in the process. Our unique approach of first determining the “root causes” of plant operating problems has saved our customers millions of dollars and helped them realize payback on repairs and rebuilds in as little as a few months. Let us show you how our air preheater inspection, repair and replacement services can save you big in the long run!
Is Your Operation Leaking Money?
Cascading Problems Corrode Your Operating Efficiency
Installing mechanical plugs to isolate damaged air heater tubes is one short-term strategy for regaining at least some of your fan and boiler capacity and slowing down and the development of new tube failures. However, it’s important to realize that something is causing tubes to fail and that the damage mechanisms will still be at work even after the plugs are installed. Those problems are often cascading in nature, causing hidden inefficiencies and other issues not just in your APH, but throughout the process.
Here are just a few facts about damaged air preheaters and how they might be costing you efficiency and corroding your profits:
The cumulative financial impact of air heater efficiency is rarely adequately measured or observed, but the results speak for themselves. By eliminating leakage in the system, plants can realize up to a 4% reduction in net fuel consumption.
Not only do improvements to your APH units cut overall energy consumption, but they should help reduce your maintenance and waste disposal costs. If the boiler is the heart of your operation, then the air preheaters are its lungs. Ultimately, repair should extend the APH units’ life and everything that they touch in your system, from fans to boilers to pollution control equipment.
In many cases, CMS customers have delayed repairs until operational impacts are already a significant problem. Often, by that time the rate of deterioration is so advanced that it can’t be ignored. Our calculator can determine this in advance before leakage balloons into a much bigger problem.
A damaged air preheater is a liability that can cost you more than system efficiency and bottom-line profits. By eliminating air leakage and returning the air preheater to ‘as built’ or better condition with improved materials for erosion and corrosion protection, Corrosion Monitoring Services has helped boiler operators across the United States achieve and exceed their environmental objectives and operate at MAXIMUM operational efficiency. CMS works to ensure that your APH performs as designed and helps keep you operating safely within applicable regulatory requirements.
The detrimental effects of a corroded air preheater can lead to environmental issues. Don’t let these potential problems compromise your operation:
On-site Inspection Services
CMS offers a complete range of inspection services that not only determine the exact extent of existing damage, but can also identify the root cause and its probable failure rate so that you can proactively plan your next steps for a longer-term solution.
Our inspectors use acoustic eye, pressure testing and other inspection equipment and techniques to isolate corrosion and erosion damage in electric utility, steel, refinery, chemical processing, pulp & paper, biomass and waste-to-energy operations throughout North America.
Comprehensive assessment programs conducted by the industry’s most experienced APH inspectors provide an accurate picture of air heaters and other critical equipment, pinpointing corrosion, fouling, and other damage that hampers operations, drains energy, and dilutes profits.
After we complete any air preheater inspection, all of our findings and recommendations are detailed in an Executive Summary Report. Depending on the type of inspection performed, the Executive Summary might include corrosion rate charts, ultra-sonic readings, failure rate metrics, detailed tubesheet maps, and maintenance recommendations.
The thoroughness of a CMS inspection helps identify where your equipment is damaged and is the first step toward ensuring that the condition of the air heater never compromises operational or pollution control objectives. Meeting those important objectives starts by hiring a contractor that has deciphered and solved nearly every air heater problem you can imagine – an experienced team member you can depend on.
High Angle Rope Inspection
CMS offers high angle rope access inspections to assess difficult-to-reach or inaccessible areas. During a high angle inspection, CMS provides a highly trained inspector, who has received 80+ hours of NFPA rope access training.Learn More
Acoustic Eye Inspection
CMS innovative acoustic eye inspection solution is designed specifically for detecting faults commonly found in industrial tube systems. These could include leaks, increases in internal diameter caused by wall loss, full or partial blockages, as well as other issues that negatively impact your operations.Learn More
Pressure testing is an effective tool that can be used to identify tube failures and determine the overall health of an air heater. During this procedure, a CMS inspector pressurizes each tube and records air leakage rates as they occur in damaged equipment.Learn More
Our highly trained and skilled inspectors significantly enhance quality control and help prevent costly outages on equipment by evaluating wear and internal degradation.Learn More
