- Abstract:
- With the advantage of fast treatment speed, large capacity, reduction, stabilization, harmless and resource utilization, sludge incineration has attracted more and more attention compared with other treatment processes. Sludge incineration is a complex process affected by many factors such as sludge calorific value, sludge treatment amount, water content of sludge, primary air, secondary air, recirculating air, burner and water spray temperature reduction, etc. Good incineration condition is crucial for the long-term, stable and efficient operation of the incinerator. Bailonggang sludge disposal phase Ⅱ project was taken as the research subject in this paper, and the effects of the above factors on the incineration conditions of bubbling fluidized bed sludge incinerator were studied. The results showed that the incinerator temperature would be higher under higher sludge calorific value, larger treatment amount and lower sludge water content. Effective measures were needed to prevent the incinerator from being over-temperature. The sand bed temperature was adjusted by matching the primary and secondary air and the sludge quantity through the excess air coefficient. The incinerator temperature was controlled by recirculating airflow. The temperature control of the incinerator by water spray depends on the amount of water sprayed，and pray water was not used to control the temperature of the incinerator without water spraying device for the small amount of water spraying.
