锅炉不同层燃烧器燃用不同煤种煤粉的分层混烧方法可避免掺混后的煤粉因燃烧特性变化而造成锅炉结渣等运行不安全因素。在对电站锅炉分层混烧取得成功经验的基础上，应用微机开发的煤粉分层混烧优化指导系统，以混烧后煤价最低为目标函数，以负荷曲线和锅炉对煤质的要求等为约
Different layers of burners burning different types of pulverized coal burning coal by the method of stratified mixing can be avoided after the blending of coal due to changes in combustion characteristics caused by boiler slagging and other unsafe factors. Based on the successful experience of multi-layer boiler mixed firing in power station, the coal-based stratified co-firing optimization guidance system was developed. The objective function is to minimize the coal price after mixed firing, and the load curve and boiler requirements for coal quality Such as about
