  • State-of-the-Art Steam Tracing

    QMax FTS: High Performance, Low Cost

    QMax FTS (Fluid Tracing System) combines performance comparable to jacketed pipe with the flexibility and low cost of standard steam tracing.

    QMax FTS is a patented, highly conductive aluminum channel that fits over standard stainless or copper tubing to maximize heat transfer from the heating medium to the process pipe. Installation is quick and simple. It effectively increases process temperatures, yet is also energy efficient because it does not continue to add unnecessary heat energy into the process once operating temperatures are achieved.

    Compared to fully-jacketed pipe, which also has high performance but required a high capital investment, QMax is a highly efficient solution as a great value. To learn more contact the team at Campbell-Seveyor or QMax_FTS_-_State-of-the-Art_Steam_Tracing.

  • The RYDER CUP! What a blast!!!

    What a week at Hazeltine! An incredible event like the Ryder Cup coming to Minnesota is in itself amazing, but when it happens to be at Campbell-Sevey CEO Brian Ross' home course, that's incredible. The Ryder Cup began in 1927 with Walter Hagan as the captain. The U.S. won then just like it did this year, but this year it was done in spectacular fashion. The event, held at Hazeltine National Golf Club in Chaska, MN, featured amazing golf by players on both teams with 122 birdies and 3 eagles made in the 202 holes played. In the end, the U.S. won by their largest margin since 1981. The team at Campbell-Sevey had a great time throughout the week. It was incredible to hear the roars from the crowd and chants of U-S-A. An unforgettable event to experience!
  • Increase System Efficiency with Steam Trap Surveys and SAGE

    Steam trap performance can significantly impact safety and overall plant efficiency, however they also tend to be neglected for long periods of time. This can be costly - as much as $300 - $3000 per trap in energy losses alone (see chart below for potential losses based on leak size). Campbell-Sevey's steam trap surveys have proven to significantly reduce failure rates. For example, here are results of a project we did for Flint Hills Resource:
    • 18,185 operating steam traps in its system
    • Annual steam trap survey for the last 15 years
    • Annual steam trap failure rate reduced to 2%
    Armstrong Launches SAGE - Smart Utility Monitoring, Measuring and Reporting To also improve efficiency, Armstrong has launched a powerful software tool - SAGE™ - that uses their patented algorithm as it analyzes data to track behavior and performance for the most advanced steam and hot water system management available today. Instead of guesswork and costly surprises, SAGE™ gives you regular updates and alerts you if an issue arises so you can take immediate action. Click to see more details about SAGE and the unique features it offers.. For more information on the best options for you to improve your system performance through better steam trap management, contact the team at Campbell-Sevey.
  • How Important is Correct Slope and Condensate Drainage on Atmospheric Steam Dispersion Piping

    When using an Atmospheric Humidifier it is important to manage the condensate in the dispersion piping properly. If condensate in the dispersion run is not drained sufficiently, back pressure can be created, leading to problems with the operation of the humidifier.

    For all Armstrong Humidifiers, such as the Armstrong HC-6000 series, EHU-800, CS-10 or GFH, the slope of the dispersion piping should be 1" per 12". The illustration shows the importance of dispersion pipe slope. If the condensate is not removed efficiently, condensate could build up creating a reduced cross section of pipe for the opposing steam to flow which can cause back pressure at the humidifier.

    Even on a system with correct slope there can still be a build up of condensate for dispersion runs that are longer than 20 equivalent feet. In these instances, it is recommend a drain be added in the middle of the dispersion run to eliminate excessive condensate.

    Symptoms of back pressure are often level control related. Too much pressure on the outlet of the humidifier causes a pressure difference between the level control measurement canister and the main steam generation tank. Sometimes this can be fixed by the addition of a fill cup extension kit, but often times, the dispersion piping issues need to be corrected. On some humidifiers there may be an issue with back pressure forcing water down the overflow into the drain.

    If you have questions about proper installation of Armstrong Humidifiers or other steam equipment, contact Campbell-Sevey. (Information from Armstrong International)

  • Test Your Knowledge: Which Device Is It?

    Which of the following helps minimize water hammer, helps drains condensate, and minimizes temperature swings?
    1. 1. Inverted Bucket Steam Trap
    2. 2. Vacuum Breaker
    3. 3. Fluid Air Coil
    4. 4. Mechanical Condensate Pump
    5. 5. Pilot Operated Regulating Valve
    And the answer is... 2. Vacuum Breaker A Vacuum Breaker is a simple, reliable device that allows air to enter a steam piping system when a vacuum is induced. When a steam system shuts down, the remaining steam condenses into water, which takes up a much smaller volume than the original steam. This creates a vacuum, which can lead to water hammer and tube damage if not relieved of in a timely way. Check out this video which shows the proper use of a vacuum breaker in a steam system. Here are our top 4 reasons for including a vacuum breaker in your system:
    1. It helps allow for complete condensate drainage under all operating conditions: on/off or modulating applications. 
    2. It helps minimize water hammer. 
    3. It helps minimize temperature swings and uneven temperatures. 
    4. It helps minimize product waste.
    All heat transfer components, whether shell-and-tube exchanger, plate-and-frame exchanger, air heating coil or any other device, require vacuum breakers. As the video shows, because the condensate piping after our coil is clear glass, you can watch condensate backing up into the coil without a vacuum breaker.  Once the vacuum breaker is allowed to operate, the coil can remain free of condensate under all operating conditions, which eliminates many issues that can shorten equipment service life and/or cause operation problems. The footage for that video was taken in our Steam Training Room located in Minnetonka, Minnesota, where we have regular training classes.  We utilize a steam boiler, glass piping, and functional glass-bodied steam traps to describe and demonstrate a variety of steam basics and advanced concepts in the 4 main areas of a steam system: Generation, Distribution, Utilization, and Condensate Return. Contact us for more information on the proper use of vacuum breakers or sign up for our Steam Energy Conservation seminars to learn more.

  • How Expansion Joints Prevent Catastrophic Failures

    To avoid catastrophic failutres a critical requirement in any steam system is accounting for pipe expansion. As pipes heat up with high pressure steam, pipes can grow up to 8 inches for every 100 feet. That growth can exert forces that break loose pipe guides and cause catastrophic failures. In order to avoid that two highly effective ways to accommodate thermal expansion is with slip and ball type expansion joints. Check out the video above which illustrates how both types of joints work. Slip Type Expansion Joints Advanced Thermal Systems (ATS) offers packed slip type expansion joints that provide an economical, safe, and reliable method of absorbing large amounts of axial pipe expansion and are ideal for systems with long straight pipe runs. Special configurations are available to accommodate as much as 24" of expansion in both single and double (48" total) expansion joints for service conditions to 1000 psig at 750°F.  Flexible Ball Type Expansion Joints ATS packed ball type expansion joints provide an economical, safe, and reliable method of absorbing large amounts of single and multiple plane displacements including rotation. Ball joints are ideal for systems with vertical pipe runs and/or natural offsets. These joints are designed to accommodate 15° to 33° of angular flex and 360° of rotation. Standard ball and slip joints include such special features as:
    • A high performance injectable packing which is suitable for operation at temperatures up to 1000°F.
    • Packing cylinder designs that allow in service packing of the joint and uninterrupted process at pressures up to 1000 psig.
    • Low friction nonmetallic internal and external guides to offer further protection of the hard chrome plated sliding slip.
    Because expansion joints’ internal and external guides must be concentric it's important to have the most reliable joint possible. For recommendations on the right slip or ball type expansion joints for your system, contact the team at Campbell-Sevey.
  • Steam Tip 26: Consider Installing a Condensing Economizer

    The key to a successful waste heat recovery project is optimizing the use of the recovered energy. By installing a condensing economizer, companies can improve overall heat recovery and steam system efficiency by up to 10%. Many boiler applications can benefit from this additional heat recovery, such as:
    • district heating systems
    • wallboard production facilities
    • greenhouses
    • food processing plants
    • pulp and paper mills
    • textile plants
    • hospitals
    Condensing economizers require site-specific engineering and design, and a thorough understanding of the effect they will have on the existing steam system and water chemistry. Use this tip sheet and its companion, Considerations When Selecting a Condensing Economizer, to learn about these efficiency improvements or contact the team at Campbell-Sevey for help. A conventional feedwater economizer reduces steam boiler fuel requirements by transferring heat from the flue gas to the boiler feedwater. For natural gas-fired boilers, the lowest temperature to which flue gas can be cooled is about 250°F to prevent condensation and possible stack or stack liner corrosion. The condensing economizer improves waste heat recovery by cooling the flue gas below its dew point, which is about 135°F for products of combustion of natural gas. The economizer reclaims both sensible heat from the flue gas and latent heat by condensing flue gas water vapor (see Table 1). All hydrocarbon fuels release significant quantities of water vapor as a combustion byproduct. The equation below shows the reactants and combustion products for the stoichiometric combustion in air of methane (CH4), the primary constituent of natural gas. When one molecule of methane is burned, it produces two molecules of water vapor. When moles are converted to pound/mole, we find that every pound of methane fuel combusted produces 2.25 lb. of water vapor, which is about 12%of the total exhaust by weight. Since the higher heating value of methane is 23,861 Btu per pound (Btu/lb), 41.9 lb of methane is required to provide one million Btu (MMBtu) of energy, resulting in 94.3 lb of high temperature water vapor. The latent heat of vaporization of water under atmospheric pressure is 970.3 Btu/lb. When one MMBtu of methane is combusted, 91,495 Btu of water vapor heat of evaporation (94.3 lb x 970.3 Btu/lb )is released up the boiler stack. This latent heat represents approximately 9% of the initial fuel energy content. The bulk of this latent heat can be recovered by cooling the exhaust gas below its dew point using a direct contact or indirect condensing economizer. It is possible to heat water to about 200°F with an indirect economizer or 140°F with a direct contact economizer. Energy Savings Potential The available heat in a boiler’s exhaust gases is dependent upon the hydrogen content of the fuel, the fuel firing rate, the percent of excess oxygen in the flue gases, and the stack gas temperature. Consider a natural gas-fired boiler that produces 100,000 lb/hr of 100-psig saturated steam. At 83% efficiency, the boiler firing rate is about 116 MMBtu/hr. At its full firing rate, the boiler consumes over 4,860 lb of natural gas each hour while exhausting 10,938 lb of high temperature water vapor each hour. The water vapor in the flue gas contains over 10.6 MMBtu/hr of latent heat. As shown in Table 2, the total heat actually available for recovery is strongly dependent upon the stack gas temperature at the condensing economizer outlet. Assume that an indirect contact condensing economizer is retrofitted onto this 100,000 lb/hr steam boiler to heat 50% of the makeup water from 55°F to 200°F and flue gases are cooled to 100°F. At these conditions, 12.75MMBtu/hr of total energy is available in the exhaust, of which 7.55 MMBtu/hr will be recovered to heat makeup water in the condensing economizer. More energy could be recovered if additional heat sinks are available. Given 8,000 hours per year of boiler operation, and a fuel cost of $8.00/MMBtu, the annual energy recovered is valued at: Annual Savings = 7.55MMBtu/hr x 8,000 hrs/yr x $8.00/MMBtu/0.83 = $582,170 Examples District Heating System A food processing plant installed an indirect contact condensing economizer on a 20,000-lb/hr boiler. The condensing economizer reduced the flue gas temperature from 300°F to 120°F, while capturing 2.0 MMBtu/hr of sensible and latent heat. Energy recovered by the condensing economizer heated makeup water, reducing deaerator steam requirements from 5,000 lb/hr to 1,500 lb/hr.
