スの熱量調整における流量制御装置。 In adjusting the calorific value of city gas, the calorific value adjustment gas is mixed with LNG vaporized gas obtained by vaporizing liquefied natural gas and BOG (evaporated gas) from the storage tank to adjust the calorific value and supply the city gas to the city gas pipe. The flow rate control device has two stages: a coarse adjustment mechanism that roughly adjusts the calorific value of only BOG (evaporated gas), and a fine adjustment mechanism that finely adjusts the calorific value of the mixed gas of the coarsely adjusted gas and LNG vaporized gas after the rough adjustment. A calorific value adjustment mechanism is provided, and the coarse adjustment mechanism of the first stage includes a BOG flow rate detector for detecting the flow rate of BOG (evaporated gas), a first flow rate control valve for the calorific value adjustment gas, and a detection signal of the BOG flow rate detector. and a controller that outputs the mixed amount of the calorific value adjustment gas to be mixed based on the first flow rate adjustment valve to perform rough adjustment of the first stage calorific value, while the second stage fine adjustment mechanism is configured to perform the coarse adjustment. a mixed gas flow rate detector that detects the flow rate of a mixed gas of coarse adjustment gas and LNG vaporized gas adjusted by the mechanism, a second flow rate control valve for the calorific value adjustment gas, and a detection signal of the mixed gas flow rate detector and a final control to output the mixed amount of the calorific value adjustment gas to be mixed to the second flow rate control valve based on the detection signal from the calorimeter that detects the calorific value of the mixed city gas to finely adjust the calorific value in the second stage; 1. A flow rate control device for adjusting the calorific value of city gas, characterized in that it is configured with a gas container.
