ENGINEERING SNAPSHOT

A compact hybrid boiler for buyers who need a lower-cost route around logs, briquettes, gas or oil.

The catalog positions VMI as a robust and economical option for severe operating conditions, with no-refractory furnace logic, balanced convection area and lower stack-gas temperature.

Steam range: 4,000 to 15,000 kg/h
Architecture: Watertube furnace + firetube body
Fuel route: Logs, briquettes, gas and oil

SPECIAL FAMILY LOG-FIRED ROUTE

Why VMI belongs in engineered special families

VMI is best read as a compact, practical route for plants that need steam generation around real fuel handling, lower acquisition cost and robust maintenance access.

Large radiant furnace area improves heat absorption without relying on refractory.
Balanced convection area and lower gas outlet temperature support economical operation.
Optional exhauster frequency inverter and combustion control help stabilize pressure and reduce energy use.

Compact route for logs and briquettes

The VMI catalog highlights furnace and grate design for log burning, with optional feeding belt support when the project requires more disciplined fuel handling.

Accessories prepared for boilerhouse routine

Water-level control, low-water alarm, safety valves, pressure instruments, blowdown valve, inspection access and reinforced chassis are part of the practical package described by the legacy material.

PRACTICAL SELECTION

A special-family option when the buyer needs compact steam generation with real fuel flexibility.

Use this VMI page as a starting point for technical discussion, not as a final current datasheet. Final scope, fuel route, accessories and availability should be confirmed by Steammaster engineering.

When to discuss VMI

Bring VMI into the conversation when the project needs 4,000 to 15,000 kg/h, simple fuel logistics, compact footprint, severe-duty robustness and a lower-cost route than larger biomass platforms.

Next recommended step

Share steam capacity, operating pressure, selected fuel, fuel dimensions, moisture expectation, ash behavior, load profile and available boilerhouse space so engineering can confirm if VMI still fits the project.
