纯低温余热发电方式的系统选择及参数优化
|
摘要
节能减排是世界共同关注的问题,工业生产中有大量余热被浪费尤其低温余热因品味低而不能被很好利用。为此本文以水泥工业为研究对象,用Matlab软件和数学偏微分方法对其纯低温余热发电方式进行优化选择。
建立第一代纯低温余热发电方式的热力系统构成模式,通过混合热效率的计算比较,选出最佳模式。
用数学偏微分方法对复合闪蒸补气式余热发电系统的闪蒸部分进行最佳分配,再结合第一代纯低温余热发电方式的相关参数边界条件及混合热效率的定义,采用Matlab软件拟合各个相关参数与混合热效率的关系图,通过对图形进行分析选出最优参数值和影响混合热效率最大的热工参数。
运用Matlab软件拟合出影响混合热效率最大的多个热工参数与混合热效率的关系图,综合分析出这些热工参数的最佳值和混合热效率的最大值,选出最优的复合闪蒸补气式余热发电系统。
对选出的复合闪蒸补气式余热发电系统进行优化前后的经济效益和社会效益比较,结果表明优化后的系统明显高于优化前的系统。
通过课题的研究,深化了纯低温余热发电系统优化选择的理论及其编程过程,尤其闪蒸压力分配采用数学偏微分方法推导,减少了繁琐的程序优化过程,同时用图形化分析出最佳热工参数值,也减少了多个热工参数值参与编程的复杂而又难以实现的优化过程。课题结论及其闪蒸压力最佳分配的通用公式对水泥企业建立纯低温余热站具有重要的理论和现实意义。
