Quick steam, load-pattern matching, in-service efficiency and computer controls deliver for one maker of performance fabrics.


Glen Raven manufactures a number of performance fabrics used for awnings, casual furniture, sails and boat canopies, and other demanding outdoor applications, including Sunbrella fabrics.


Founded more than a century ago, Glen Raven today is a leader in the creation of performance fabrics used for awnings, casual furniture, sails and boat canopies, and other demanding outdoor applications. Based in Glen Raven, N.C., Glen Raven Technical Fabrics LLC recently upgraded its textile dyeing and finishing infrastructure by installing five Miura EX-300 industrial steam boilers. Engineered for quick startup, fuel economy and reduced emissions, Miura boilers provide Glen Raven with the flexibility it needs to meet the ever-changing demands of its manufacturing processes.

“We made a lot of system changes when we went from our two previous large boilers to our smaller bank of five Miura boilers,” says Mike Harrington, project engineer for Glen Raven’s Technical Fabrics Group. “The new system is paying off, and [the] Miura boilers are a big part of that. We have seen improvements and increased efficiencies.”

“We’re running anywhere from 80 to 87 percent efficient with the Miura boilers,” says Steve Holt, recently retired head operator and plant engineer at Glen Raven. “We have an erratic steam load, but you can bring these boilers up fast and have them online in about ten minutes.”

“Demand swings greatly,” adds Harrington, “but we can fire the Miura EX-300 boilers off in sequence, so we don’t have a big boiler sitting there idle.”

Glen Raven’s multiple installation of five compact Miura EX-300 steam boilers can be turned on or off in varying numbers to match prevailing load patterns, thus saving fuel and water, as well as minimizing the emissions typically produced by idling boilers. In addition, the NOXrating of Miura’s EX Series boilers can be as low 30 ppm, depending on the model of the boiler.

Glen Raven’s five Miura boilers supply steam to the company’s process dye houses. “We’re heating water, and getting to temperatures of 265°F [129°C] in pressure vessels to do textile dyeing,” Harrington explains.

“We send steam about a quarter of a mile down the road to the other plant,” says Holt, “and we don’t have any problems with wet steam. Miura boilers are also safer and a lot easier to operate than the old boilers, with not near as much maintenance.”

“With their computer controls, on-board diagnostics and the safeties that are in there, Miura boilers just don’t require the high level of manual observation that old, larger boilers did,” Harrington agrees.

Glen Raven’s boilers were purchased from Boiler Masters in Greensboro, N.C. “Boiler Masters did a great job working with our team and helping with the transition from our old boilers,” notes Harrington. “They also do maintenance for us, so it’s a good relationship that has been built out of this project.”

“We continue to be very positive about our investment in Miura boilers, and look forward to many years of payoff with it,” Harrington concludes. “We know we are getting a return.” PH
