In this system, the combustion process begins with the controlled release of volatile gases. As the fuel transitions onto the grate, it reaches a state of pure carbon, facilitating high-efficiency combustion. Simultaneously, the liberated volatile gases interact with secondary air to undergo complete secondary combustion, ensuring maximum thermal recovery. This secondary air is delivered to the hopper via an external damper or a dedicated gasification air fan.

The moving grate components are manufactured from high-grade chrome-nickel alloy castings to withstand rigorous operational conditions. The furnace operates at temperatures ranging between 950–1050°C. The grate mechanism is designed with a modular, plug-in pin connection architecture for simplified maintenance. Propulsion is delivered to the grate assembly via a camshaft driven by a high-torque hydraulic power unit.

The lower structure consists of a robust chassis fabricated from steel plate or structural profiles, housing the ash collection chambers. Maintenance access is strategically provided through both the lower section and the upper screen pipe area. The fore-hearth system, integrated with the moving grate, is constructed from water-cooled pipes. These pipes are St35.8 seamless drawn steel, conforming to DIN 2448 / EN 10216-2 standards. All collector pipe apertures are precision-machined using laser or plasma cutting technology on advanced pipe-processing equipment.

To accommodate varying fuel grain sizes, the fuel bed depth on the grate is adjustable via a mechanical gate (drawer) system. Furthermore, the integration of precision-engineered refractory applications within the moving grate system significantly enhances overall combustion efficiency.
