This paper discusses the combustion characteristics of water emulsified fuel produced by swirl impinging mixer. The experiments are given in a test boiler and a commercial boiler. Flame temperatures, flame shapes and exhaust emissions are measured in the test boiler, and thermal efficiency is tested in the commercial boiler. The test data show the water in oil makes the flame wider and shorter, the flame temperature lower and the NOx and smoke lower. Also, the commercial boiler test shows the thermal efficiency increases as well as the emissions decrease.
