Rotary grate steam boilers are hybrid-type boilers that combine water-tube and fire-tube technologies within a single body. The water-tube combustion chamber, mounted on a rotating grate system, is precisely designed to create a large-volume furnace, ensuring maximum flame length, heat radiation, and high combustion efficiency.

The fire-tube section of the boiler is designed as a two-pass system to achieve optimum performance at the required capacity. Flue gases pass through the smoke tubes at controlled velocities, allowing efficient heat transfer and maximizing the utilization of combustion energy for steam production.

A large combustion chamber volume is essential for solid fuel applications. The extended flame path inside the boiler enables most of the generated heat energy to be retained within the system, significantly improving overall thermal efficiency and reducing fuel consumption.

Thanks to its large steam volume, the system can instantly respond to sudden peak steam demands. The water-tube combustion chamber also enables rapid steam generation, ensuring stable and reliable operation under varying load conditions.

Maintenance operations are designed to be simple and efficient. The smoke tubes can be easily accessed by opening the front and rear covers, allowing quick inspection and replacement when necessary.
