FUEL OIL EMULSIFIERS
For complete combustion of any oil in the burner, fuel needs to be properly atomized in the firing chamber. In major burners this atomization is achieved by the spray nozzle, this is called as primary atomization. With the help of Emulsification, we can achieve secondary atomization of fuel inside the firing chamber which helps incomplete combustion of fuel to increase the overall efficiency of the system.
When flame takes place the water in oil emulsion gets vaporized explosively due to rapid heating, resulting in dispersion within individual fuel droplets. The water vaporization is the conversion of the water droplets to steam, in turn, produces rapid expansions of the surrounding oil droplets resulting in very fine atomization of the fuel, this is called as secondary atomization.
In this state of fuel, effective surface area of fuel droplets increases resulting in complete combustion of fuel. Emulsification is blending of furnace oil and about 10 % of water with an emulsifying agent. The solution needs to be hated up to 50 Deg.C & mixed properly with circulation pump for 3 to 4 hrs. For proper blending, Emulsified water in furnace oil can be separated with the help of De-emulsifying agent only. CRISTOL Fuel Oil Emulsifiers are the additives that help to make the stable emulsion of fuel oil with the water.
