掺烧神华烟煤技术改造热控逻辑设计及应用

Burning Shenhua bituminous coal technological transformation of thermal control logic Discussion and Application

介绍了神皖马鞍山万能达发电有限公司,在#1～#4锅炉掺烧神华烟煤技术改造中,热控部分的逻辑策略设计及应用情况。在防爆、防结焦和确保锅炉效率的前提下,制定了逻辑策略并予以实施,锅炉及其制粉系统控制采用分组态控制方式,根据入炉燃料的变化和运行的需要,将原控制组态分成贫煤位控制组态和烟煤位控制组态两个组态,保证了锅炉在燃用神华烟煤工况时的安全和稳定运行。

Thisarticle describes the of Shenhua Anhui Maanshan Wannengda Power Company Limited in #1~4boiler blended with Shenhua bituminous coal technological transformation of the thermal control logic strategy.In explosion-proof, anti-coking and to ensure that the boiler efficiency, the premise of a logical strategy to develop and be implemented, the boiler and its milling system is controlled by the sub-configuration control, the original control configuration according to the needs of changes in the fuel into the furnace andruncontrol the configuration of the lean coal and bituminous coal-bit control configuration is divided into two configuration, to ensure safe and stable operation of the boiler when blended with Shenhua bituminous coal.
