在以节能为中心的技术改造和结构改革中对节能投资项目进行评估是十分重要的。一、评估原则对某工厂、某设备进行节能技术改造,其措施的选择受到技术水平、物质条件特别是资金的限制。那么,如何选择经济效益最大、节省投资的措施呢?应根据现有技术、物资,资金等条件,来预测完成后的节能效果、经济效益、维护运行费用以及使用寿命等,对各种节能措施进行比较。如某生产玻璃瓶的工厂,一座玻璃池炉热能利用率只有20％,要提高热能利用率以降低能耗,办法很多。可改变炉体结构,以提高熔化率;可改换余热风比例、烧
It is very important to evaluate energy-saving investment projects in technological transformation and structural reforms centering on energy conservation. I. Assessment Principles The energy-saving technological transformation of a certain factory and equipment is limited by the technical level and material conditions, especially the funds. Then, how to choose the most economically effective and cost-saving measures? According to the existing technology, materials, funds and other conditions, to predict the completion of the energy-saving effect, economic benefits, maintenance costs and operating life, etc., for various energy-saving measures Compare. For example, in a factory producing glass bottles, the utilization rate of thermal energy for a glass tank furnace is only 20%. To improve the utilization of thermal energy to reduce energy consumption, there are many ways. The structure of the furnace can be changed to increase the melting rate; the ratio of residual hot air can be changed and burned
