糖厂锅炉汽包水位三冲量控制方案探讨

摘要

Boiler was an indispensable power unit in sugar industry, it not only provided steam for turbine, but also supplied heat for evaporation, sugar boiling and honey centrifuge. Along with the produce expand of the sugar mill, the boiler, as for the power and heat source, was developing toward the larger capacity, higher performance and higher efficiency. Level control of boiler was the guarantee for safety production and high quality of steam, thus serious study of the control scheme was very necessary.%锅炉是制糖企业必不可少的重要动力设备,它所产生的蒸汽不仅为汽机提供动力,还能够为蒸发罐、煮糖罐、分蜜机等提供热源.锅炉汽包水位的控制是安全生产和提供优质蒸汽的保证,影响锅炉汽包水位的2个主要因素为给水量和蒸汽负荷.因此深入研究其动态特性、制定和实施锅炉汽包水位三冲量控制方案是十分必要的.
