In the context of Vietnam’s rapid industrialization, energy-intensive sectors such as cement, ceramics, metallurgy, glass, construction materials, and food processing play a vital role in driving economic growth while simultaneously exerting immense pressure on energy demand and greenhouse gas emissions. At the core of these production lines are various types of industrial kiln and furnace, from firing and incineration kilns to melting kilns, which consume a significant portion of fuel and directly determine product quality, production efficiency, and operational costs. Therefore, enhancing the energy efficiency of industrial kiln and furnace is not only a direct economic solution by reducing fuel, operation, and maintenance costs, but also a critical lever for boosting competitiveness, ensuring energy security, and achieving the emission reduction targets Vietnam has committed to. In this context, developing a reliable reference document that can be regularly updated and accurately reflects on-site operational practices regarding high-efficiency industrial kiln technologies is an urgent necessity.
