LX Series Models

Miura’s LX Series boilers occupy 50% less floor space than typical firetubes, and do not require tube pull space. Double your capacity in the same space, or reduce space requirements by half for new construction. Miura’s compact design means much smaller radiation losses and larger fuel savings. Floating headers mean fast start-up. Miura boilers produce fast steam in less than 5 minutes from a cold start-up. Standard firetubes require 1 to 1.5 hour start-up times. Miura’s unique design yields significant time and fuel savings.

Product Description

LX Series Model Design – Gas/Low NOx Series Low and High Pressure Steam Boilers
The Miura LX Series design consists of rows of vertical tubes sandwiched between two rectangular 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 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.

Additional Benefits

Low NOx “No Furnace” Boiler
Cool, soft flame wraps around the tubes from a flame spread over a large surface area. This naturally controlled burn results in unbelievably low NOx, compact size and high efficiency.

Full Steam Output In Less Than 5 Minutes
Floating headers mean fast start-up. Miura boilers produce fast steam in less than 5 minutes from a cold start-up. Standard firetubes require 1 to 1.5 hour start-up times. Miura’s unique design yields significant time and fuel savings.

Smaller is Better
Miura’s LX Series boilers occupy 50% less floor space than typical firetubes, and do not require tube pull space. Double your capacity in the same space, or reduce space requirements by half for new construction. Miura’s compact design means much smaller radiation losses and larger fuel savings.

Early Warning Scale Monitor
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 LX models are equipped with a thermocouple 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 scale can be removed to restore the boiler to 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.
