These combustion tests were conducted by a team of scientists and engineers from Battelle laboratories in Frankfurt, Geneva, and Columbus. The influence of dne concentration of Carbonex iron (1 ppm) premixed with the light oil was evaluated as a function of boiler load (firing rate) and excess air. The measurable and reproducible results of the field evaluation provided the following information: • Pretreatment of light Swiss oil with 1 ppm Carbonex iron: Reduced particulate loading by 67 percent and volatile particulate fraction by 68 percent at full load and low (12 percent) excess air, Reduced particulate loading by 34 percent, particulate carbon by 20 percent, and particulate volatile fraction by 33 percent at half load and ultralow (8.5 percent) excess air, and . Had no direct effect on NO , CO, or HC emissions, particulate size, or the already acceptable combustion efficiency. • With 1 ppm Carbonex iron premixed into the light oil, the industrial boiler could be fired at about 9 percent excess air at half load with acceptably low CO and zero smoke emissions, whereas without Carbonex, such performance was only achievable at much higher levels of excess air (30+ percent). • About a 2 percent overall additional reduction in all pollutant emissions, including NOx could be realized by virtue of the increase in thermal effltiency gained by being able to cleanly and stably fire the boiler at reduced levels of excess air. |
