Ammonia decomposition gas generator is liquid ammonia as raw material, in the presence of catalyst heating decomposed hydrogen-containing 75%, 25% hydrogen-nitrogen mixed gas containing nitrogen, ammonia decomposition gas generator has a simple structure, low investment, high efficiency, through the FC series of purification of the company easy access to a more satisfactory protection gas. Gas purity can reach dew point:-60 ?, amount of residual ammonia: 5ppm, suitable for all kinds of uses of hydrogen.
