Experimental investigation of the geometry effects of furnace on the pollution emissions in a liquid fuel combustion

One of the main parameters which affects the combustion behavior of a furnace (pollutant emission, temperature distribution, etc.) is the geometry of the furnace. In the current work,the pollutant emissions and combustion efficiency of two different cylindrical furnaces, having thesame length-to-diameter ratio, are experimentally investigated. The experiments are performed in three different flow rates of gas oil, as the fuel of the furnaces. The TESTO-350XL gas analyzer is used formeasuring the temperature and the combustion species. It is also recognized that the increase in thefuel flow rate results in an increase in the amount of NOx formation in both case but has a greater influence on the smaller furnace (furnace A). The variation of CO concentration with respect to fuel flow rate shows that there is an optimum flow rate in both furnaces which represents the minimum amount of CO emission.. The results show that the increase in the flow rate results in a decrease in the efficiency and an increase in the exhaust temperature in both furnaces
