Miura: Not Just for Process Heat
With pollution, climate change and energy prices a concern in both the public and private sectors, the DOE has issued purchasing specifications for energy-efficient commercial steam boilers. Miura modular boilers, long used in process applications due to their ability to deliver on-demand steam and reduced environmental footprint, provide capabilities and characteristics that can help commercial enterprises conform to those guidelines.
According to U.S. Department of Energy's Federal Energy Management Program (FEMP): “A boiler system should be capable of meeting the building’s peak heating demand and also operating efficiently at part-load conditions. Selecting the right system and properly sizing a boiler requires knowledge of both the peak demand and load profile. If building loads are highly variable, as is common in commercial buildings, designers should consider installing multiple small (modular) boilers. Modular systems are more efficient because they allow each boiler to operate at or close to full-rated load most of the time, with reduced standby losses.”
The guidelines also note that federal agencies are required to buy either Energy Star-qualified or FEMP-designated products, both of which are, by definition, the most energy-efficient products available.
Smaller than traditional counterparts, boilers from the New York-based company utilize precision computer control and use natural gas or oil to heat multiple water-tubes within a pressure vessel rather than heating a large water tank, as with older-style boilers. This compact, once-through design requires less fuel and water than conventional boilers, according to Miura. Yet, it enables the systems to produce steam in five minutes or less and deliver BHP outputs comparable to much larger units. The boilers save, on average, about 20 percent annually in fuel costs.
