3 terms and definitions
The following terms and definitions apply to this document.
3.1
Waste heat using wasteheatrecovery
Based on the ambient temperature, the use of recoverable heat energy in the high temperature flue gas produced by the production process of the submerged arc furnace.
3.2
Preheating equipment
The use of flue gas waste heat or other heat source to preheat the raw materials.
3.3
Hot charging technology hotcharging andhotdeliverytechnology
Furnace raw materials or with the ratio of the charge through the flue gas waste heat or other heat preheating equipment, reducing the charge moisture content, at higher temperatures
The process of loading into the submerged arc furnace.
Principle and Process
The use of charge preheating device (heat exchange hopper, rotary kiln, etc.), the smelting furnace generated by the flue gas waste heat or other heat sources (such as sintering smoke
Gas waste heat, cooling water vaporization waste heat, etc.) on the ratio of the completion of the charge by the preheating equipment for heating, the material will be installed in the hot material into the submerged arc furnace,
Reduce the moisture content of raw materials into the furnace, to improve the temperature of the furnace into the raw materials. The process is shown in Figure 1.
