摘要： 分析了钢铁联合企业副产煤气在煤气柜和自备电厂锅炉间的优化分配问题,就煤气柜的柜位控制、自备电厂锅炉燃料负荷变化、外购燃料价格变化等对操作成本的影响展开讨论,针对这些问题设置了相应的操作惩罚函数并建立了钢铁联合企业煤气供应系统优化分配数学模型.通过模型求解可知,煤气供需差距通过煤气柜和自备电厂锅炉之间的优化分配得到解决,减少了外购燃料的消耗,降低了锅炉燃料负荷的频繁变化,提高了发电效率,实现了煤气的零放散,使煤气供应系统安全、经济、稳定运行.

Abstract: The optimal distribution of the gas as the by-product of an iron and steel complex between the gas holder and the boiler in its self-supply power plant is discussed, involving the effects of the position control of gas holders, change in fuel loading of the boiler and variation of purchase price of additional fuel on the cost of operation. An optimal gas distribution model is thus developed with a relevant penalty function deduced to solve these problems. The results indicated that the optimal gas distribution between gas holders and self-supply power plant is available to decrease the fuel purchased externally and reduce the frequent change in fuel loading of the boiler, thus improving the power supply efficiency and enabling the zero gas emission so as to make the operation of gas supply system safe, economic and stable.
