Main Article Content


Brick production is an essential component of the construction industry, contributing significantly to the development of infrastructure and housing worldwide. This study evaluates the energy efficiency and environmental impact of a multi-chamber brick kiln in Vietnam. The study was conducted through a detailed field survey of the kiln, which included measurements of energy consumption and pollutant emissions. The results show that the kiln has a moderate level of energy efficiency, as indicated by the specific energy consumption of 2,035.1 kJ / kg output brick. However, the kiln also produces pollutants, including SOx, CO, and NOx. The study provides recommendations for improving the kiln's energy efficiency based on the results of the energy analysis. Overall, this study highlights the importance of improving the energy efficiency as well as the environmental performance of a Multi Chamber Brick Kiln in Vietnam and provides valuable insights for policy-makers and industry stakeholders.
