GAS LEAK DETECTION SYSTEM AND DETECTION METHOD FOR SEALED CONTAINER TYPE HEAT EXCHANGER, AND GOVERNOR HEATER SYSTEM

摘要

PROBLEM TO BE SOLVED: To quickly detect a gas leak in a sealed container of a sealed container type heat exchanger. SOLUTION: A gas leak detecting part 10 is provided with respect to the heat exchanger 1 comprised by providing a heat exchange part 1B communicated with gas communication pipings 2A and 2B in the sealed container 1A. The gas leak detecting part 10 is provided with a gas accumulation part 11 formed in a peak part of the sealed container 1A of the heat exchanger 1, a float 12 detecting a liquid level decline due to accumulation of leaking gas in the gas accumulation part 11, and a detecting means 13 for detecting a positional decline of the float 12 in the gas accumulation part 11. A gas leak in the sealed container 1A is detected by a detection signal of the detecting means 13. COPYRIGHT: (C)2005,JPO&NCIPI
