| Outline of Final Research Achievements |
Thermal efficiency has improved by using high-temperature vapor produced by spraying water vapor along with flame from a burner. This study aims to apply high-temperature steam heating mechanism in a high-efficient industrial furnace and household gas range. Water vapor-added industrial metal melting furnace has been researched. In this study, the effect of surrounding environment to the furnace is examined, and possibility of heat transfer enhancement is estimated. As a result, surrounding experimental condition has little effect on the change of heating ability, and optimum amount of water supply to the apparatus was discussed. Too much water injection leads to more consumption of heat as latent heat of water in phase change, and exceeds the effect of water vapor in heat transfer. There is a possibility of suitable total water supply, despite that there is no significant change in gas usage in water injection case compared with no water injection.
