TOSH–The Orthopedic Specialty Hospital is an advanced facility providing sports medicine and physical therapy. Located in Murray, Utah, Intermountain Healthcare’s TOSH also has an advanced and efficient steam boiler system from Atlanta-based Miura Boiler to provide the essential heating capacity needed in a modern hospital facility. Utilizing steam heating technology often used for industrial process heating operations, Intermountain Healthcare was able to leverage the Miura system in combination with controls customization focused on site-specific load management to help meet its long-term energy-optimization goals.
The system includes custom integration that allows the facility to use an iPad to cycle boilers, turn them on and off, change the pressure points, and switch them around, says Troy Jensen, corporate energy manager for Intermountain Healthcare. Miura boilers save an average of 20 percent annually on energy costs over traditional boiler designs, but Jensen notes that TOSH’s Miura boilers achieved a 42 percent fuel-cost reduction during January 2014 alone. He attributed the savings to the integration of custom software and a boiler control system of his own design that interfaces with each Miura boiler’s built-in precision microprocessor-control technology.
Microprocessor intelligence built into Miura boilers includes the BL micro controller, which keeps track of multiple individual monitoring points. The advanced diagnostic system can identify challenges to smooth operation and recommend solutions on its easy-to-read display. Jensen notes that the system can monitor practically everything in the system, from hardness of the water, to boilers’ activity, to alarms. The simplicity of the operation has also reduced the amount of special training for operators.
In addition to the on-demand steam and energy-conservation benefits of Miura boilers, the systems release reduced levels of nitrogen oxides (NOX) and carbon dioxide. Miura boilers achieve low-NOX performance by reducing the temperature of the boiler’s flame, which in turn reduces the amount of excited nitrogen atoms available to bond with oxygen to form nitrogen oxides. NOX emissions are reduced to around one-quarter of what traditional fire-tube boilers emit.
