Abstract
This paper presents the study of a development and assessment for bio ethanol mixing fuel boiler. Recently, bio ethanol is expected as one of the measures for global warming. However, we try to use it only for an alternative gasoline source, and we do not nearly consider other ways of using it. Then, we focus to boiler whose fuel is heavy oil or kerosene, and develop bio ethanol mixing fuel and bio ethanol mixing boiler. The boiler has the same performance of combustibility, and reduces almost 19% CO_2 and 27% ELP (Environmental Load Point) in life cycle compared with the boiler whose fuel is heavy oil or kerosene.
