Abstract
PURPOSE:To prevent the liquefied gas in a line from being flown into a combustion chamber, by a method wherein the liquefied gas remaining in the line running from a turning-off valve to a burner is exhausted through a purging line to the outside during the flow stoppage that is required at the time when liquefied gas in a liquid state is burned. CONSTITUTION:A residual liquid purging line 4 is connected to a lower portion of a piping 3 between an emergency turning-off valve 1 and a burner 2, the said line 4 being connected to a flare stack through the medium of a residual liquid purging electromagnetic valve 5 and a liquid pot 6. An opening area ratio of the burner 2 to the purging line 4 is set to be, say, about 1/20. The valve 5 simultaneously opens when the valve 1 closes. Since a resistance at a burner 2 side is far larger than that at a piping 4 side due to the opening area ratio thereupon, almost no liquefied gas flows to the burner 2 side, but it flows to the piping 4 for a short time. This permits the prevention of flow of unburning liquefied gas in a piping 3 into a combustion chamber following closure of the valve 1.
