为有效提高垃圾焚烧炉安全性、经济性和稳定运行管理水平，在深入了解垃圾炉燃烧工况变化和运行人员操作经验的基础上，开发了自动燃烧控制（Auto Combustion Control，ACC）策略，主要包括主蒸汽流量、一次风流量、二次风、氧量、料层厚度及炉排和推料器速度控制。投运结果显示：机组主蒸汽流量24 h内的波动最大值为58.061 t/h，最小值为54.183 t/h，控制变化的相对标准偏差为0.85%；发电量日均值为54.10万kW•h，相对标准偏差为1.80%；供电量日均值为45.69万kW•h，相对标准偏差为2.21%，焚烧炉整体运行平稳，发电量和供电量波动较小；一个月内热灼减率统计平均值约为2.3%，相对标准偏差约为5.7%；省煤器出口含氧量24 h内的波动最大值为5.71%，最小值为2.79%，含氧量控制变化的相对标准偏差为9.66%，满足垃圾焚烧炉的运行控制要求。

In order to improve the safety, economic and stable operation management level of waste incinerators effectively,an auto combustion control(ACC)strategy was developed based on indepth understanding of the waste incinerator combustion condition variations and operating experience of operators, which mainly included the main steam flow control, the primary air flow control, secondary air flow and the oxygen content control, material layer thickness control and the speed control of grate and pusher. The application results show that the maximum fluctuation of the main steam flow within 24 hours is 58.061 t/h, the minimum value is 54.183 t/h, and the relative standard deviation for controlling the variation is 0.85%. The daily mean value of power generation is 541 000 kWh,and the relative standard deviation is 1.80%;the daily mean value of power supply is 456 900 kWh, the relative standard deviation is 2.21%. The overall operation of the incinerator is stable, and the fluctuations of power generation and supply are small. The average of slag burning rate within one month is about 2.3%, and the relative standard deviation is about 5.7%. Within 24 hours, the maximum value of oxygen content fluctuation at the economizer outlet is 5.71%, the minimum value is 2.79%, and the relative standard deviation for controlling the variation of oxygen content is 9.66%, which meet the operation control requirements of the waste incinerator.
