Tình hình sử dụng và tiết kiệm năng lượng trong sản xuất clanhke xi măng tại Việt Nam

Abstract

The Vietnamese cement industry has a large production capacity and plays an important role in national socio-economic development. However, it is also one of the most energy-intensive and greenhouse-gas-emitting sectors in the industrial field. This study aims to assess the current status of energy consumption—including both thermal and electrical energy—in clinker production in Vietnam.

Survey results from cement plants show that the average thermal energy consumption is approximately 824 kcal/kg clinker, while the average electrical energy consumption is about 61.8 kWh/t clinker. Large-capacity production lines that have implemented integrated energy-saving measures and waste heat recovery (WHR) systems demonstrate significantly lower energy consumption compared to smaller and older-technology plants.
