铸造行业的节能潜力最大的部分是熔化工序。前一段我们对沈阳市28个系统342合三吨以下冲天炉进行调查和测试,认为在冲天炉节约能源上是有不少潜力可挖的,有不少工作可做,现就几个具体问题提出以下意见。一、从风焦平衡观点选择合适的风机目前与冲天炉配套的风机功率普遍偏大,存在“大马拉小车”现象。从风焦平衡的观点,为减少动力消耗,应怎样选择风机。首先,我们应该知道每公斤焦炭充分燃烧需要多少空气量。根据理论计算,每公斤焦炭完全燃烧所需的空气量L_理为: L_理=0.089C+0.033s(米~3/公斤焦炭)式中C——焦炭中固定炭含量(％); S——焦炭中含硫量(％)
The most energy-saving part of the foundry industry is the melting process. In the previous paragraph, we conducted a survey and test on the cupola below 342 tons and below in 28 systems in Shenyang City. We believe there is a lot of potential to save energy in the cupola. There are a lot of work to be done. Make the following comments First, choose the appropriate fan from the wind balance point of view Currently supporting fan cupola power generally larger, there is “big horse car” phenomenon. From the wind’s point of view of balance, in order to reduce power consumption, how to choose the fan. First, we should know how much air is needed to burn each kilogram of coke. According to the theoretical calculation, the amount of air required per kilogram of coke for complete combustion is: L_ = 0.089C + 0.033s (m ~ 3 / kg coke) Where C-- fixed carbon content in coke S - Coke sulfur content (%)
