Movable and fixed iron grates
These grates provide a stable foundation for fuel combustion. The movable grates facilitate ash removal and allow for better control of airflow and combustion efficiency, while the fixed grates maintain the structural integrity during operation.
Refractory lining of the furnace
The thick refractory lining helps retain heat in the furnace and protects the structure from high temperatures. This material is known for its excellent thermal insulation properties, which enhance overall combustion efficiency.
Primary and secondary air channels
The separation of air ducts ensures controlled combustion. Primary air is usually introduced directly into the furnace to ignite the fuel, while secondary air is introduced later in the combustion process to ensure complete combustion, reducing emissions and improving efficiency.
Water-cooled fuel supply auger connection
Water cooling of the auger connection is crucial for safety, as it helps prevent backfire —a situation where flames can travel back through the feed mechanism. Additionally, it extends the lifespan of the screw winding by reducing thermal stress and wear. .
