Safe Use of Natural Gas in Ceramic Furnace Burners
Heat radiation source in ceramic furnaces can be either electric or with combustible, such as LPG or natural gas (NLG). Recently, due to electric shortage and costs, natural gas turned up to be a better alternative to provide heat source to furnaces. Paper presents a study on risk analysis of the use of natural gas in burners of ceramic furnaces. Safety concern to identify hazard causes and consequences was performed, people vulnerability was also studied. Prevention and protection analysis was elaborated by PHA (Preliminary Hazard Assessment) technique. After hazard identification, explosion shock wave consequences as well as people and or material vulnerabilities were performed with the TNO method. Natural gas leakage followed by fire jet and CVE – confined vapour cloud explosion calculations and its effects to the people and facility materials were also provided. Finally, safety measures to prevent and or protect equipment and furnace operators were proposed.
