Factors affecting changes in the outlet temperature of the Lurgi furnace

Thread Content

Dear sea friends, I would like to create a presentation on this topic and hope everyone can offer some suggestions. Factors affecting changes in the outlet temperature of the Lurgi furnace: My personal summary includes 1. the position of the flame layer ； If the fire layer is high, the exit will be at a higher level; the same applies in reverse. 2. When wind tunnels or channeling occur under operating conditions ； At this time, the outlet temperature is unstable, with significant fluctuations. 3. The jacket liquid level is low ； A low jacket fluid level affects the heat absorption by the jacket, resulting in an increase in the heat carried away. 4. Moisture content in coal ； The higher the moisture content, the more heat needs to be absorbed for drying, and thus the lower the outlet temperature; the same is true in reverse. 5. Size of the oxygen-to-vapor ratio ； A higher oxygen-to-gas ratio will lower the reaction temperature for vaporization, and thus the outlet temperature will also decrease; the same is true in reverse. 6. Selection of the vaporizer temperature ； The higher the temperature, the higher the vaporization temperature will be, and the outlet temperature will increase as well; however, it must be kept within the range of ash fusion. 7. Air distribution effect of the furnace grates ； It has good air distribution, low resistance, and the outlet temperature will decrease somewhat. 8. The instrument detection signal is inaccurate ； 9. Internal leakage in the jacket 10. Insufficient coal addition, affecting the increase in outlet temperature.
