Abstract

The combustion of low-quality fossil fuels by industrial burners release toxic exhaust emissions such as NOx, CO and HC. Introduction of water in combustion have been proven to improve combustion efficiency and reduce toxic emissions in several studies. One of the methods of water introduction in combustion is water emulsified fuel. In present study, the combustion of Malaysian Diesel grade 2 (D2), and Water-in-Diesel (W/D) emulsion fuels with 5%, 10% and 15% water volume (labelled as E5, E10 and E15, respectively, using an industrial burner was investigated. The aim of the study is to measure the fuel consumption, flame temperature, and exhaust emissions of the industrial burner fuelled with the test fuels to find a suitable setting for an optimum combustion of the W/D emulsion fuels. It is found that the flame temperature of all the tested fuels were the highest at fan damper 2 setting. Additionally, the combustion of E5 showed the highest flame temperature compared to other tested fuels. The fuel consumption for all W/D emulsion fuels were lower than that of D2. The NOx emission of the tested fuels increased with the increase of fan damper number, whereas the CO and HC emission showed otherwise.
