Miura LX 100 in practice
Miura's LX rating table prints the LX 100 at 100 BHP, 3,450 LB/HR steam output and a standard-pressure operating range of 70-150 PSI, with a low-pressure configuration at 15 PSI. Standard-pressure efficiency is 85%.
The table prints As low as 9 PPM NOx for this size. The fuel row reads 'Natural Gas or Propane' for every LX model group. Published build codes for this size group are: LX-100SG-12 and LX-100SGN-12 (9 ppm); LXL-100SG-07 and LXL-100SGN-07 (low pressure).
Miura describes the LX as producing steam in less than five minutes from a cold start-up, with a compact footprint that can double steam capacity in the same space. The line is sold for modular Multiple Installation (MI) plants where units stage with demand and provide n+1 redundancy. No official Canadian-sales statement was found.
Best suited to
- Industrial steam plants documenting an installed LX 100 against Miura's published rating table
- On-demand steam loads in the 3,450 LB/HR class
- Modular MI plants that stage multiple boilers with n+1 redundancy
