<P>PROBLEM TO BE SOLVED: To provide a gas heating system equipped with a gas leakage detection function where an extremely small amount of gas leakage is detected at an early stage and its availability is not limited to the specific type of a heat exchanger. <P>SOLUTION: This gas heating system 1 heats gas by performing heat exchange between a heated liquid supplied to a heat exchanger 5 disposed in a humidification liquid circulation route 3 and a gas to be heated using the heat exchanger 5. The gas heating system 1 is characterized by including a pot 7 disposed in the humidification liquid circulation route 3, a discharge pipe 9 that discharges the circulating heated liquid toward the upper part of the pot 7, an outlet 11 arranged in the pot 7 that discharges the heated liquid stored in the pot 7 to the humidification liquid circulation route 3, a gas storage portion 12 disposed at the upper part of the pot 7, and a liquid surface detection means 13 arranged in the gas storage portion 12 that detects the liquid surface of the gas storage portion 12. <P>COPYRIGHT: (C)2013,JPO&INPIT |
