Title:
AUXILIARY LIQUEFIED GAS SUPPLY SYSTEM AND AUXILIARY LIQUEFIED GAS SUPPLY METHOD
Document Type and Number:
Japanese Patent JP2018179243
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an auxiliary liquefied gas supply system which continuously executes liquefied gas supply with low power consumption.SOLUTION: An auxiliary liquefied gas supply system 1 comprises: an evaporator 12 which causes liquefied gas sent from a liquefied gas pump 13 to transit to gas with a first temperature lower than an ambient temperature; a heat exchange section 16 which heats the gas with the first temperature to a second temperature higher than the first temperature through heat exchange with a heat medium; a heating section 14 which heats the gas with the second temperature to a third temperature higher than the second temperature with an electric heater; auxiliary gas supply piping which sends the gas produced by the heating section 14 to main piping; a pressure gauge 20 which measures inner pressure of the main piping or the auxiliary gas supply piping; a generator 15 which supplies electricity to the electric heater and/or liquefied gas pump 13; and a generator control section 31 which controls the generator 15 in a manner that operates the same when the inner pressure measured by the pressure gauge 20 becomes equal to or lower than a threshold value.SELECTED DRAWING: Figure 1
