The Analysis of Energy Saving in the Process of Producing Mineral Wool: a Case Study in Shanxi Province

Abstract

Melting is the most energy consuming process in the manufacture of mineral wool. This paper dealt with evaluation of two types of energy saving measures in the process of producing mineral wool. In order to detect the energy saving measures that can also provide economic profits, the study examined the following measures: utilization of flue gas heat, thermal power supplement with coke oven gas. The analytical method used for energy saving were material balance and energy balance. It is found that the most effective energy saving measure is thermal power supplement with coke oven gas. The maximum energy saving is up to 39.3% when coke/coke oven gas is 50:1. The economic cost of saving runs to 3.017 million RMB every year.
