摘要
为了合理利用煤资源、提高经济效益以及保证锅炉稳定运行,煤电企业往往要进行配煤操作来满足要求.根据火电厂相关煤质参数的要求,通过煤质分析建立了以水分、灰分、硫分、发热量等参数为约束条件,以配煤成本最低为目标函数的配煤优化数学模型.利用Matlab求解得出各煤种最优配比,使成品煤在煤种质量达标的情况下成本最低.实例证明,本方法有利于节约能源和提高效益,对指导动力配煤具有重要意义.
Power stations often undertake blending operations to rationalize the utilization of coal resources to imptove economic benefit and to stablize operation.In order to achieve the lowest cost,the optimized mathematical model of blending coal,with coal moisture,ashcontent,sulfur,calorific value as its constraint conditions,is established.The optimal proportion of blended coal is obtained by Matlable.Experiments show that this method can save energy,improve efficiency and decrease cost.
