Dum Dum Pops manufacturer is already tasting success after switching to Miura boilers to maximize efficiency and reduce fuel costs.
Spangler Candy, headquartered in Bryan, Ohio, has been in business for more than 100 years and today manufactures more than 8 million Dum Dum Pops daily, along with over 1.5 million candy canes and more than 600,000 Saf-T-Pops per day.
Generating steam for manufacturing purposes, efficiently and cost-effectively, is one of the responsibilities of Paul Gackel, P.E., director of facilities/utilities. So when it was time to switch out four of the company’s five firetube steam boilers, which were generating up to 900 BHP, Paul called his dealer, Combustion Mechanical of Fort Wayne, Ind., and asked them to look into current boiler technology that could support the operation while also reducing fuel costs.
“Combustion Mechanical did a lot of research and came up with Miura Boiler as the company that would satisfy our needs,” said Gackel. “So off we went to visit their North American manufacturing operations in Brantford, Canada. We were impressed.”
What convinced Gackel and the team from Combustion Mechanical to select New York-based Miura was the attention to detail, the overall “heavy-dutiness” of the product and the potential for saving oil and gas costs.
“We were running a pretty efficient operation, but with Miura technology, we estimated an additional 10 to 20 percent fuel saving, and that really got our attention,” Gackel added.
Spangler Candy switched out four of its five current boilers between Thanksgiving and Christmas, relying on Industrial Contracting & Engineering in Angola, Ind., to handle the assignment. There was no downtime and no production delay.
By year end, the four Miura Boiler EX Series 200 BHP horsepower units were operating as expected. EX Series boilers are dual fuel fired using natural gas, propane or No. 2 fuel oil. Depending on the model, NOX rating is available as low as 30 ppm.
All Miura Boilers produce steam in 5 min. using the exclusive floating head design, an advance that results in gas and oil savings of up to 20 percent. In a multiple installation (MI), Miura boilers can be turned on or off as needed, allowing Spangler to meet peak demand hours while operating at greater efficiency throughout the day and reducing wear and tear. Miura boilers also require less space and have an online maintenance system with a “sliding window feature” that records an event four seconds before it occurs, so it can be diagnosed and corrected faster.
“I felt very confident that we would satisfy our needs with Miura boilers and achieve the fuel cost savings that would enhance our productivity,” added Gackel. “The first month we could test actual fuel costs ‘apples to apples’ was February 2007 (as compared to February 2006). The results suggested a savings of 14.87 percent on fuel costs and the additional benefit of conserving natural resources.”
Gackel went on to discuss how primary pressure regulating valves (PRV) helped to make a big difference in achieving maximum efficiency. “Miura boilers can step down easily and having good control of output pressure made a big difference for us in achieving our goals. Plus, even though the Miura technology was new to our operators, they did seem to like it a lot more than our previous boiler, since with the self-diagnostics there was a lot less to go wrong.”
