CRYOGENIC POWER GENERATING DEVICE

摘要

PURPOSE:To secure a gas permeable quantity, which secures the constant operating load of a turbine, at all times even if a hourly variation in the amount of gas used at an LNG consumer station is large enough, as well as to operate the turbine in a highly efficient manner, by installing a cryogenic regenerator tank, while providing for a heat storage-radiation system, in case of liquefied natural gas cryogenic power generation. CONSTITUTION:An LNG feed quantity to be fed to a turbine 4 via a vaporizer 3 is set at the specified quantity Q required for securing the preset constant operating load P of the turbine 4, but since the amount of gas used at an LNG consumer station 7 is hourly varied, if a demand quantity Q' at the consumer station 7 is the case of Q'>Q, a portion for the difference of Q'-Q is fed to the consumer station 7 by way of a cryogenic regenerator tank 9 with drive of a pump 2 and each selecting motion of three-way selector valves 11-13 and thereby cryogenic medium inside the cryogenic regenerator tank 9 stores the heat in the midway. And, when Q>Q' is the case, a portion for the difference of Q-Q' is liquefied by each selecting operation of these three- way selectors valves 12-14 and 11 and cooling at the cryogenic regenerator tank 9 and a booster pump 17, then returned to the vaporizer 3, whereby operation load is made constant at all times.
