A system for transferring and conditioning a cryogenic liquid includes a replenishing tank containing a supply of cryogenic liquid, a bulk tank and a pump positioned there between. The pump causes a stream of the cryogenic liquid to flow from the replenishing tank to the bulk storage tank. A heat exchanger and parallel by-pass line are positioned between the pump and bulk storage tank. A flow control valve diverts a portion of the stream to the heat exchanger so that it is warmed and rejoined with the remaining cryogenic liquid flowing through the flow control valve. The warmed stream then flows to the bulk storage tank. The flow control valve is adjusted based upon pressures within the bulk storage tank via a pressure line in communication with the head space of the bulk storage tank and a pneumatic controller or a pressure sensor in the bulk tank head space and a programmable logic controller.

A gas turbine combustor according to claim 1, wherein the flame-stabilizing means comprises contracting the areas at the outlets of the pre-mixers to be smaller than the areas of the swirling air passage portions at the swirler, so that the velocity of the pre-mixture blown out from the pre-mixers are increased in the axial direction to weaken the disturbance of the pre-mixture that is mixed with the pilot flame. 4. A gas turbine combustor according to claim 1, wherein the flame-stabilizing means is a circulating stream generator means provided on the inner surface of the pilot cone to stabilize the pilot flame. 5. A gas turbine combustor according to claim 4, wherein the circulating stream generator means consists of protuberances formed on the inner surface of the pilot cone. 6. A gas turbine combustor according to claim 5, wherein a protuberance is formed by folding the rear end edge of the pilot cone. 7. A gas turbine combustor according to claim 4, wherein the protuberance is an air injection means for injecting the air into the inside from the inner surface of the pilot cone. 8. A gas turbine combustor according to claim 1, comprising a stagnation preventing means which is formed by extending portions of the circumferential rear ends of the pre-mixers, between intermediate connection points where neighboring pre-mixers are connected to each other and outer connection points where each pre-mixers are connected to a inner casing forming a combustion chamber, toward the downstream end connected smoothly to the inner casing, so that generation of a stagnation region is prevented.
