Celebrating its 60th year in business, Miura boilers offer a range of benefits attracting a growing number of customers in a number of industries. Among these benefits are cold start to full steam in under five minutes; overall improved efficiency (fuel savings average about 20% compared to traditional brands, based on customer comments); enhanced reliability through its modular design; advanced controls and advanced monitoring and a best-in-industry safety record with zero catastrophic vessel failures resulting in casualty.
With more than 140,000 units in operation world-wide, Miura has never had a pressure vessel explosion resulting in casualty. The company’s “safer-by-design” engineering, combined with its unique boiler geometry, means that catastrophic vessel failure is practically impossible and day-to-day safety issues related to installation and operation are minimized.
Miura boilers also have numerous safeguards beyond primary vessel safety to ensure not only safe operations, but also high efficiency and reliable operation. Plus, the company’s unique design provides a number of key advantages including reducing the amount of costly square footage required, and making installation and standard maintenance that much simpler.
Miura’s LX Gas/Low NOx Series, Low and High Pressure Steam Boiler (available in boiler models ranging from 50-300 horsepower) use natural gas or propane and are available in a range of steam pressure options (300 MAWP, 170 MAWP or 15 MAWP). Its compact size allows most models to fit through an industrial 7-foot doorway, while its naturally low-NOx ratings are as low as 9 ppm depending on model. This meets or exceeds current and proposed regulations for nitrogen oxide emissions levels. Hot water boilers are also available depending on models.
The company’s EX Gas/Oil Series High Pressure Steam Boilers (available in boiler models starting from 100 horsepower, and in 50 horsepower increments up to 300 horsepower) are the most versatile industrial steam boilers in the world. The EX design minimizes carryover and produces 99+% dry saturated steam in less than five minutes from a cold start. Faster startup means less fuel used, greater savings and more responsible use of precious natural resources.
The LX-Series design consists of vertical watertubes in a rectangular array, while the EX-Series utilizes vertical tubes in a circular array. Both headers of each series are encased in a castable refractory with only the tubes exposed to flame and/or combustion gases. The upper header is attached to the lower header only by the tubes. As the tubes expand and contract, the headers float up and down accordingly.
The floating header concept allows for even thermal expansion of the tubes, therefore reducing stress points within the boiler. The leaky tube problems associated with firetube and bent watertube designs have been eliminated.
