Division 22 23 Ebook Page 154 SCR Board at Brandon Shores Plant Case Study

Case Study Mike Kilmon is a 17-year veteran of the industrial insulation business and he has used a lot of insulation products in that time. When a job came up recently requiring material for 200,000 square feet of a Selective Catalytic Reaction unit, Kilmon set out to get "the best product out there." His choice: SCR Board from Owens Corning. "I was a little apprehensive at first," admits Kilmon, who manages the Baltimore Office of Insulation Specialties, Inc. "I'm a die-hard fan of mineral wool; I've used that product for a number of years. But I'm very satisfied with the Owens Corning SCR Board. Once we put the panels on, we can see that it's doing the job; it's knocking down the heat. "We use a temperature gun to check every area that we insulate and I have been really pleased. Some temperatures were above 200 degrees (F), and it's gone down to under 90 F. So it's doing its job. The plant's impressed with it, and I am happy with it." Rolland Hemling, contract administrator at the site, also admits to being a mineral wool fan who is impressed with the performance of the Owens Corning SCR Board. "Oh yeah, I was surprised to see it do the job that it's doing," says Hemling. "We like it. We're using a significant amount of it. We originally planned to do only the sidewalls but we decided to also do the top of the units with SCR Board." What does he like best about the product? "The light weight," he says. "And the insulation is just as good as the mineral wool." "We're putting a significant amount of it on the structure, the precipitator, and we are covering a massive area, so the lighter the insulation the better. The light weight also makes the product easier to handle." Not only are individual SCR boards light and easy to handle, but Owens Corning also made a packaging change that enhances productivity. Bill Tolliver, technical leader for pipe and mechanical products at Owens Corning, explains the situation. "They were getting 3" product and we were putting eight pieces in each package," says Tolliver. "That made the packages 24" thick. The contractor was having difficulty getting them up to the work site because they had to pass the material through a guardrail that has an opening of about 19 inches. "The installers had to open the bundles and pass them through a few pieces at a time so it was a hassle handling the material. We developed some new codes and packaged the material six pieces to a package. That totals only 18 inches so they are able to get it through the handrails without a problem." Owens Corning Sales Representative Steve Doehring says a Thermal Analysis of the SCR unit convinced the power company to invest in additional insulation even though the SCR unit had only been in service for a few years. "The payback period was unbelievably short," says Doehring. "I believe the cost to re-insulate the system was something like $2 million, and the payback for them with additional energy savings was within the first year. And so beyond that (first year) it was all newfound money, if you will. It was big dollars in terms of short payback and significant long-term savings." Once the decision was made to insulatate the SCR unit, Kilmon said he went to work to get the best product for the job. We like it. We're using a significant amount of it.
