  • Having issues with Pipe Expansion? Install Expansion Joints

    A critical requirement in any steam system is accounting for pipe expansion as the lines are heated. With high temperature steam, pipes can grow up to 8 inches for every 100 feet.

    Without specifically engineered equipment to take these expansions into account, the pipe growth can exert forces that break loose pipe guides and cause catastrophic failures.

    Two highly effective and safe ways to accommodate for the thermal expansion is with slip and ball type expansion joints. Check out the video above which illustrates how both types of joints work. 

  • CS Insight: Command Performance at Carnegie Hall

    The story of Carnegie Hall begins in the middle of the Atlantic and ends with an unforgettable trip by Campbell-Sevey’s Charlie Thomas.

    In the spring of 1887, Andrew Carnegie (the rich industrialist) and his newlywed wife were on board a ship traveling to Carnegie’s native Scotland for their honeymoon. Over the course of the voyage, the couple developed a friendship with Walter Damrosch, the 25-year-old conductor and musical director of the Symphony Society of New York who shared his vision for a new concert hall in New York City. It was there that the idea of Carnegie Hall was born.

    From this germ of an idea grew a legendary concert hall that has drawn the world’s greatest artists to its stages. Those artists now include Charlie Thomas from Campbell-Sevey.

    Charlie has been a member of the Metropolitan Men’s Choir for 21 years and the choir recently had the opportunity to join many other men’s choirs from across the country and sing at Carnegie Hall. About 275 male voices, including 20 of Charlie’s fellow choir members and an alumni choir from West Point, were joined by an orchestra made up of members from the New York Philharmonic.

    “The concert began with performances by the Rochester Philharmonic Youth Orchestra, followed by the Distinguished Concerts Orchestra and Distinguished Concerts Singers International, a mixed of men and women. Both were fantastic,” said Charlie. “When they were done and our choir started filing in, and 9 rows of risers filled the stage from wall to wall, and then the orchestra took the stage, the sold out audience knew they were in for something special.”

    And special it was. “We started singing and the auditorium filled with a powerful male sound, the walls resonated with power.” Charlie added.

    The joint choir performed Testament to Freedom written by Randall Thompson. The work is based on writings of Thomas Jefferson from 1775-1776 as our nation was being created. The piece starts and ends with the powerful lyrics “The God who gave us life, gave us liberty at the same time: the hand of force may destroy, but cannot disjoin them”, speaking to the unity that was being created here during that time.

    “Singing those powerful words about the birth of our nation, in Carnegie Hall, and on Presidents’ Day weekend, was awe inspiring,” Charlie said. “The work brought our minds back to what it must have been like back then, in a divided nation much like we have now, to forge this country. It was an incredibly emotional experience.”

    At the last cut off of the 25-minute voice and orchestral work, Charlie shared that “tears streamed down my cheeks as the audience rose to their feet with thunderous applause.”

    Before leaving New York, Charlie and the other members of the Metropolitan Men’s Choir, along with their family and friends, visited the 9/11 memorial where the choir was able to give one final performance as their gift to the fallen.

    Andrew Carnegie proclaimed that Carnegie Hall “is built to stand for ages”. For Charlie Thomas, it is a memory that will last for ages.






  • Steam Tip 10: Recover Heat from Boiler Blowdown

    Heat can be recovered from boiler blowdown by using a heat exchanger to preheat boiler makeup water. Any boiler with continuous blowdown exceeding 5% of the steam rate is a good candidate for the introduction of blowdown waste heat recovery. Larger energy savings occur with high-pressure boilers. The following table shows the potential for heat recovery from boiler blowdown. 

    Example: In a plant where the fuel cost is $8.00 per million Btu ($8.00/MMBtu), a continuous blowdown rate of 3,200 pounds per hour (lb/hr) is maintained to avoid the buildup of high concentrations of dissolved solids. What are the annual savings if a makeup water heat exchanger is installed that recovers 90% of the blowdown energy losses? The 80% efficient boiler produces 50,000 pounds per hour (lb/hr) of 150-pounds-per-square-inch-gauge (psig) steam. It operates for 8,000 hours per year. The blowdown ratio is: 

    Blowdown Ration = 3,200 ÷ (3,200 + 50,000) = 6.0%

    From the table, the heat recoverable corresponding to a 6% blowdown ratio with a 150-psig boiler operating pressure is 1.7 MMBtu/hr. Since the table is based on a steam production rate of 100,000 lb/hr, the annual savings for this plant are: 

    Annual Energy Savings =
     [1.7 MMBtu/hr x (50,000 lb/hr/100,000 lb/hr) x 8,000 hr/yr]/0.80 = 8,500 MMBtu 

    Annual Cost Savings =
    8,500 MMBtu/yr x $8.00/MMBtu = $68,000

    Blowdown Energy Recovery: Blowdown waste heat can be recovered with a heat exchanger, a flash tank, or flash tank in combination with a heat exchanger. Lowering the pressure in a flash tank allows a portion of the blowdown to be converted into low-pressure steam. This low-pressure steam is most typically used in deaerators. Drain water from the flash tank is then routed through a heat exchanger. Cooling the blowdown has the additional advantage of helping to comply with local codes limiting the discharge of high-temperature liquids into the sewer system.

  • Test Your Knowledge: Insulation

    Which type of insulation is economic and energy efficient for piping carrying saturated steam?

    a. Fiber bricks 

    b. Ceramic fiber 

    c. Calcium silicate

    d. Fiberglass

    The Answer...

    d. Fiberglass – Fibrous insulation is composed of small diameter fibers which finely divide the air space. But why is insulation needed?

    First, steam is a hot gas that desperately wants to give up its latent heat energy and turn back into water. It will give up that tremendous amount of energy to anything that’s colder than it is. 

    Typically steam leaves a boiler anywhere from 240 to 340 degrees F depending on its pressure. That’s hotter than just about everything else in the system. So when the steam hits a cold pipe, it will quickly make that pipe hot by condensing and releasing its latent heat energy. The hot pipes lose heat through radiation and convection condensing more steam. The colder the surrounding conditions are, the faster the steam will condense, and that’s why we recommend using Thermal Blanket insulation. The insulation keeps the steam hot, like a thermos bottle. 

    At Campbell-Sevey we recommend using INSULTECH Blankets. The blankets provide immediate energy savings, capturing 80% of surface radiant and convective heat loss, with the added benefits of quick installation, quick removal and quick reinstallation.

  • Unit Heaters That Perform Under Pressure

    When it comes to long life under tough industrial conditions, Armstrong unit heaters stand the test. Even in the most severe environments where coil leaks and corrosion are costly, Armstrong coils maintain high efficiency and output. 

    The reason is that components like motors, bearings, tubes, enclosures and fins are heavy-duty to ensure lasting performance.

    Armstrong’s options for fin material, pitch, height and type, for example, all have a bearing on heat transfer. That explains why their heating cores last much longer and perform with greater efficiency than competitive units. Knowing how to balance these and other factors is the key to a cost-effective solution. That knowledge is perhaps the most important of Armstrong’s many hidden benefits.

    Contact the team at Campbell-Sevey to learn more about what unit heater options are best suited for your needs. 

  • Test Your Knowledge: Heat Transfer

    Which of the following shows the correct heat transfer?




    The Answer:


    Two bodies brought in thermal contact will change their temperature until they are at the same temperature.  In the process of reaching thermal equilibrium, heat is transferred from one body to the other.

    Suppose we have a system of interest at temperature 250ºF surrounded by an environment with temperature 70ºF.  Since TS > TE heat flows from the system to the environment.  If TS < TE heat flows from the environment into the system. Heat flow is a result of a temperature difference between two bodies. Heat flow is considered to be positive when heat flows into the system, negative if heat flows out of the system, and the flow of heat is zero if TS = TE.
