Optimal Design for High Performance Industrial Furnace Applied High Temperature Air Combustion Technology

摘要

We propose unit furnace to construct general data base for practicla industrial furnace design. According to thsi philosophy we built test furnace and evaluated comparatively the experimental resutls and calcualtion results in high-temperature air combustion. the absolute value of NO gained by using a general CFD code has many uncertain points, but the tendency of the NO value agrees with measured value. Therefore, we can use the calcualtion results to understand tendency and predict NO_x value. We constructed many data bases for high-temperature air combustion including tehniques for making the uniform furnace temperature, raising the furnace temperature and low NO_x foramtion. We designed a practical high performance industrial furnace using the above mentioned data, then we achieved 30% saving energy, over 20% of downsizing and clearing the environmental regulation of NO_x value.
