Miura Boiler - Low NOx Industrial Steam Boilers; Steam Generators, Hot Water Boilers, Ancillary Products

The MIURA EX Series design consists of rows of vertical tubes sandwiched between two annular headers. Both headers 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.

This 'floating header' concept, aided by forced flow, greatly reduces stress and allows for the use of cold feedwater without the fear of significant thermal shock. The 'leaky tube' problems associated with firetube and bent watertube designs have been eliminated.

Ultra Compact Design Saves Space and Costs
MIURA's Ex series boilers occupy 33% less floor space than typical firetubes, and do not require tube pull space. Compact design means much smaller radiation losses and larger fuel savings.

Full Steam Output Within Five Minutes
Floating headers mean fast start-up. MIURA boilers produce fast steam in 5 minutes or less from a cold start-up. Standard firetubes require from 1 to 1.5 hour start-up times. MIURA's unique design yields significant time and fuel savings.

Dry Steam
The MIURA EX design minimizes carryover and produces dry 99+% saturated steam through a 3-stage process:

1. Initial separation in the tubes
2. Second separation in the upper header and baffle plate
3. Final separation in the cyclone separator.

Early Warning Scale Monitors
Scale is a problem all boilers have to deal with. Scale forms when boiler feedwater is not properly treated. Advanced scale formation acts as an insulator; only an eggshell thickness of scale results in a 10% efficiency loss, higher fuel bills and possible damage to the boiler system.

As standard equipment, all MIURA EX models are equipped with thermocouples attached directly to a tube. Should scale begin to form, the MIURA boiler will alert the operator - allowing the operator to trace and repair the source of the water hardness. The boiler can then be acid rinsed to restore its original efficiencies - saving tens of thousands of dollars in wasted fuel and repair bills.

Unbeatable In-Service Efficiencies
MIURA's computer-aided design results in optimal heating surface transfer with minimal water content for fuel-to-steam efficiencies of 85%. Typical firetube designs can deliver up to 83% fuel-to-steam efficiencies. However, in actual use, MIURA averages 10 to 40% fuel savings over standard firetube designs.

How does a 2% difference in fuel-to-steam efficiencies translate into a 10 to 40% Actual Fuel Savings? Contact your local MIURA representative for details.
