[0002] The suspended calcining furnace is an advanced calcining equipment. The material is suspended through a fixed structure, and the heat-carrying gas is used to suspend the fine particles or powdered materials in the hot air flow. Intense heat and mass transfer processes occur between the gas and the solid. The material is in a suspended state in the furnace, and the heat and mass transfer rate is high. The gas in the furnace is in an intense turbulent state, the fuel burns evenly, the furnace temperature is uniform, the combustion is complete, and the heating speed is fast. The existing calcining furnace heating structure mostly heats and burns the material through a gas combustion device.
