This report describes the general overview of tunnel kiln technology and presents the brick making process, design elements of tunnel kiln and key technical aspects of its different components and processes that should be optimised during operation. Key performance indicators such as investment and operating costs, expected lifespan, productivity level, land use, fuel consumption and fuel type, energy efficiency, emission level and emission type are analysed for tunnel kiln technology.
The document is prepared for Infrastructure Development Company Limited (IDCOL) as part of technical assistance for financing brick kiln improvements in Bangladesh. The document provides best practices recommendations on the acceptable range of the described parameters as a guide for the evaluation of tunnel kiln projects in Bangladesh and can also be used as a reference document for other parts of the world where similar operating conditions exist.
CCAC, UN Environment Finance Initiative (UNEP FI) and Frankfurt School of Finance & Management join hands to implement the project titled ‘Technical assistance for financing brick kiln...
