multiple installation (mi) boiler system
five 300hp boilers = 1500hp capacity
On-Demand Steam
boiler turns on only when necessary
Miura boilers produce steam in less than 5 minutes from a cold startup. This allows them to create steam when you need it and only when you need it, making Miura boilers the most efficient industrial boilers on the market.
Scalable Steam
Long-Term Flexibility
With Miura’s Multiple Installation System (MI), companies can configure an on-demand boiler system to address their fluctuating needs. This system makes it easy to add units to your Miura boiler system to meet steam requirements as your operations grow.
Planned Reliability
n+1 redundancy
As compared to the “two boiler system,” where one large boiler carries the load and the second large boiler acts as a backup, Miura uses small units in a modular design to function as one large steam system. Therefore, one small unit provides N+1 backup, allowing the reduction of total system horsepower. As a bonus, Miura can reduce construction space by half or double the output in the same space.
Traditional boiler challenges miura modular solutions
Q: How can we increase steam capacity for use when production demand increases?
Traditional Boiler
Challege
Large firetube boilers are usually sized to supply the maximum facility demand when installed. When demand increases, the large horizontal pressure vessel drum creates space constraints for additional units. Any supplemental firetube boilers have to be kept in idle mode to be ready when spikes occur, which wastes fuel and energy. Challege
Miura Modular
Solution
Miura’s LX-series modular boilers grow with you. The compact design makes it easy to add units when production requires more steam. Boilers automatically turn ON/OFF based on facility demands, so boilers only used during peak loads don't have to stay on all the time, thereby saving energy and cutting costs. Solution
Q: Is it possible to avoid production interruption during planned maintenance and yearly inspections?
Traditional Boiler
Challege
The firetube boiler size and complexity to open makes yearly boiler inspections and maintenance a burden. It interrupts production for at least two to three days to let the boiler cool, empty, disassemble, inspect, reassemble, fill and heat. Challege
Miura Modular
Solution
With Miura boilers, production interruptions are a thing of the past. Operators inspect and maintain the multiple smaller units in a modular system one at a time. This eliminates the need to shut down production for servicing. Solution
Combustion Sequence
Miura’s proprietary once-through watertube design has collected many engineering milestones such as increased in-service efficiency, world-class reliability and an industry-leading safety record. The safer-by-design system produces steam from a cold start in minutes, making it the best choice for energy efficiency.

Air Intake
Air & Fuel Mixing
Combustion Exchanger
Heat Recovery
Air Intake
Ambient air pulled through replaceable filters mounted on the air box and propelled into the wind box by a blower.
Air & Fuel Mixing
Combustion air mixes with fuel gas in the gas chamber and flows into the wind box. Then, the mixture passes through the burner and ignites.
Combustion Exchanger
The corrugated burner projects a large flame in the heat exchanger where combustion and heat transfer occur simultaneously. Heat transfer is optimized with finned tubes in the lower temperature zone
Heat Recovery
The combustion exhaust exits through the heat recovery economizer that uses exhaust heat to preheat the incoming feed water. 
Water Journey
Miura’s watertube technology stems from over 60 years of perfecting the design to enhance efficiencies. From the feed water supply to steam in your facility. Miura’s complete steam solution efficiency preserves resources, and recycles energy for sustainability and cost savings. Intuitive sensors monitor each step of the water journey and integrate with the complete system.

Economizer Feed Water Preheat
Incoming feed water is routed through a heat recovery economizer to increase the efficiency of the boiler.
Main Pressure Vessel
Water fills the tubes from the bottom of the pressure vessel and receives heat from combustion gas. It turns into steam and flows upward.
Steam Collection Drum
Raw steam funnels into the collection drum where the dry steam starts to rise to the top while moisture sinks to the bottom.
Steam Separator
The steam separator allows the dry steam to exit to the process equipment and recirculates the moisture back to the pressure vessel. 
LX series steam boiler modulation
The ability to produce full steam output in less than 5 minutes from a cold start, and to easily turn ON and OFF with short purge time adds flexibility in the boiler operation. The operator can easily turn boilers ON and OFF when needed based on the steam demand and operation schedule. When combined with the BP panel, Miura’s proprietary multiple boiler controller, the system can be modified and monitored together providing the operator with an all-inclusive peace of mind.
