[0003] The existing stepped precombustion furnace does not have a good anti-blocking function, which causes the slag produced during the combustion process of the precombustion furnace to easily cause blockage of the furnace channel, resulting in the inability of materials to flow smoothly, affecting the combustion efficiency. Severe blockage may cause local overheating, damage equipment and even cause a fire, and there are certain limitations. Utility Model Content
