Auxiliary Boiler (Oil-Fired) · Boilers
The Mihara MZ Series is an oil-fired auxiliary boiler. It is normally installed in the engine room connected to feedwater, steam, fuel, combustion-air and exhaust systems. It is designed for independent production of steam when exhaust heat is unavailable or insufficient. In operation, a burner releases fuel heat into boiler pressure parts and water. The supplied entry gives no additional verified capacity, pressure, power or dimensional figure for this model. Compared with neighbouring models, the relevant differences are steam capacity, pressure, burner fuel, heating-surface arrangement and controls; these must be confirmed from the installed documentation rather than inferred from the model designation alone. Service and survey attention should concentrate on burner/combustion, water level, pressure parts, water treatment, safety valves and interlocks. For exact ratings, dimensions, tolerances, test limits and model-specific settings, refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Inspect pressure parts or heater coils, heat-source/burner and refractory where applicable, gas-side cleanliness, circulation/feed systems and water or thermal-fluid condition. Verify level, pressure, temperature, flow, safety valves and shutdown/interlock functions applicable to the design. Review treatment, blowdown, soot-cleaning and operating records and use manufacturer/class procedures for pressure tests.
Carry approved gaskets, valve service parts, relevant pump seals/bearings, temperature/pressure/level sensors and heat-source-specific spares such as burner ignition/flame components or soot-cleaning parts. Pressure-part repair materials should only be used under approved manufacturer and class procedures.
