<P>PROBLEM TO BE SOLVED: To provide an ammonia gas-supplying system which makes it possible to completely consume ammonia gas in an ammonia gas tank, when the ammonia gas tank is replaced, without stopping the supplying of ammonia gas. <P>SOLUTION: The ammonia gas-supplying system is provided with a control device 7 which conducts; the first control which opens a tank output valve 10B<SB>3</SB>of an ammonia tank 10A and a tank output communication valve 4 in case that the ammonia tank 10A, for example, of the ammonia gas-supplying system is a tank whose content is to be completely consumed; the second control which sets a pressure of an accumulator 50B of an A-system 5, which corresponds to the ammonia tank 10A, to a high level compared with a pressure of an accumulator 60B of a B-system 6, which corresponds to an ammonia tank 20A, in case that a level of the liquid ammonia in the ammonia tank 10A decreases; and the third control which opens the tank output valve 20B<SB>3</SB>of the ammonia tank 20A connected to the B-system 6 and closes the tank output communication valve 4. <P>COPYRIGHT: (C)2008,JPO&INPIT |
