就我国炼油厂目前的保温状况来看,降低固定能耗的潜力很大。所谓固定能耗是与生产负荷无关的能耗,即指工厂设备与管线等的散热损失。搞好保温设施,降低固定能耗,是节能的有效措施之一。本文对保温层厚度、保护层材料的选择都提出了经济的计算方法。经济保温厚度,简单地说,就是选用一定期间内保温费用和散热损失费用合计为最小时
As far as the current insulation condition of China’s oil refineries is concerned, there is great potential for reducing fixed energy consumption. The so-called fixed energy consumption is energy consumption that has nothing to do with the production load, that is, the heat loss of plant equipment and pipelines. Making good insulation facilities and reducing fixed energy consumption is one of the effective measures for energy conservation. In this paper, economic calculation methods are proposed for the selection of insulation layer thickness and protective layer materials. The economic insulation thickness, simply put, is the selection of the total cost of insulation and heat loss costs for a given period
