<p>A system for storing ammonia comprises a combined gas and flow detector (4) that is able to measure a flow of ammonia as well as to detect gases other than ammonia. The system further comprises thermally activatable ammonia stores (1), which can be activated to release ammonia upon heating. When the ammonia stores (1) are not heated, the system is below ambient pressure and any leak will cause foreign gas to enter the system. Therefore, the gas detector (4) is used to detect the presence of such foreign gas, which allows to detect leaks. The gas detector (4) is a thermal detector using a single heater (6) and two temperature sensors (7, 8) for detecting gas flow as well as foreign gas.</p> |
