Abstract
Emulsion fuel is a very attractive fuel because of its energy saving and pollution prevention properties. We investigated and compared the combustion efficiency of B-C oil and emulsion fuel i.e. fuel made from the mixture of B-C oil and waste water. By installing an R-type thermocouple and an optical pyrometer on each side of the boiler, and by placing a combustion analyzer at the point of gas emissions, We were able to measure and compare each flame temperature, combustion rate and the concentration of emitted gas when B-C oil and emulsion fuel are burned. The following results were obtained: The flame temperature of emulsion fuel at the front and rear of the boiler is about 50$^{\circ}C$ lower than the flame temperature of B-C oil. The reason for this difference in temperature is that both latent and sensible heat is lost due to the moisture in the waste water of emulsion fuel. An analysis of emitted gases shows that when emulsion fuel is used polluting substances decrease also the concentration of CO becomes considerably lower. The combustion efficiency for B-C oil and emulsion fuel is 85.5% and 84.8% respectively.
