Patent ID: 8771598

Claim:
An ammonia storage system comprising: an ammonia containing section; a thermally activatable ammonia store disposed in said ammonia containing section; a valve, wherein opening of the valve allows ammonia gas to flow out of the ammonia containing section through the valve and wherein when said valve is closed, in the absence of a leak, the ammonia containing section contains pure ammonia; a duct of the ammonia containing section connecting the ammonia store to the valve; a heater for thermally activating said ammonia store, wherein thermal activation of the ammonia store by the heater releases ammonia into said ammonia containing section, and further comprising a gas detector disposed in the ammonia containing section at the duct and configured to detect a thermal conductivity of gas within the ammonia containing section; wherein the system is adapted to issue an alert if the detector detects a thermal conductivity different from the thermal conductivity of pure ammonia.
