In 2018, Miura launched its Quick Ship Xpress (QSX) program. Now, the program is changing the way some steam boiler users make buying decisions, as QSX impacts the highly-expensive rental market, reduces the need to continually tinker with “end-of-life” boilers, and can even assist in Disaster Recovery efforts, according to the company who demonstrated these steam boilers during ProFood Tech 2019 in Chicago.
“Quick Ship Xpress is an amazing advantage for our customers who might otherwise be spending tens of thousands of dollars on a rental boiler,” says Paul O’Donnell, Miura’s vice president of strategic development. “The program is also a major life-saver for customers who may have waited too long to order a new boiler, and instead finds themselves constantly patching up an old, inefficient model, while trying to avoid downtime costs.
With QSX, Miura users can have a new “cold start to full steam in five minutes” boiler from 50 - 600HP (multiple 300HP units), in the time it usually takes to install a rental unit.
With more than 140,000 units in operation, Miura has never had a pressure vessel explosion resulting in casualty. The company’s “safer-by-design” engineering, combined with its boiler geometry, means that catastrophic vessel failure is practically impossible and day-to-day safety issues related to installation and operation are minimized, according to Miura.
Miura boilers also have numerous safeguards beyond primary vessel safety to ensure not only safe operations, but also high efficiency and reliable operation.
Miura’s LX Gas/Low NOx Series, Low and High Pressure Steam Boiler use natural gas or propane and are available in a range of steam options (300 MAWP, 170 MAWP or 15 MAWP). Its compact size allows most models to fit through an industrial 7-foot doorway, while their naturally low NOx (nitrogen oxides) ratings are as low as 9ppm 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.
Miura’s EX Gas/Oil Series High Pressure Steam Boilers (available in 100HP, and in 50 HP increments up to 300HP models) are the most versatile industrial steam boilers in the world. The EX design minimizes carryover and produces 99 percent dry saturated steam in less than 5 minutes from a cold start.
The LX-Series design consists of vertical water tubes 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 water-tube designs have been eliminated.
