| Abstract | ||
| The black smoke emitted from brick kiln's stacks induced a serious health and noxious problem and consequently attracted the public and formal attention. The problem is basically attributed to the primitive combustion of fuel oil leading to incomplete combustion and consequently evolution of high concentration of smoke and carbon monoxide. The solution was to improve the combustion system of fuel oil. One of the six proposed systems was studied. This system depends on injecting fuel oil under high pressure in consecutive pulses, so that fuel oil is combusted completely and efficiently, and hence decreasing pollutant emissions. The results of emission measurement in six brick kilns before and after the combustion improvement system installation are presented. The system has proved high reduction efficiency with smoke [up to 96.3%] and carbon monoxide reduction [up to 97.9%] and moderate efficiency with sulfur dioxide reduction [up to 75.7%] where as nitrogen dioxide had an inverse trend; since its concentration increased after the system operation up to about three folds. However, still its concentration is below emission limits. The preliminary economic feasibility study has revealed saving of about 40% of fuel oil consumption and pay back of capital investment in two years and half. In conclusion, the applied system has been proven to be feasible technically and economically. | ||
