Analysis of Leakage Consequences of Urban Natural Gas Pipeline Based on ALOHA Software
Based on ALOHA software,the con-sequences of gas pipeline leakage are analyzed under certain conditions.After a natural gas pipeline leak,if it is immediately ignited,a jet fire will be generated,and the maximum consequence area reaches 30 m.If the volume fraction of natural gas in the vapor cloud enters the explosion limit range at some time after leak-age,the vapor cloud explosion will occur after it is igni-ted,and the maximum consequence area reaches 31m.According to the consequence analysis of natural gas pipeline leakage,it is recommended to set up a 30 m pipeline protection area and take protective measures.
