Hydrogen is indispensable for the bright hardening of metals. But, viewed from the standpoint of safety,

hydrogen gas is by no means an advantageous atmosphere. Dissociated ammonia atmosphere or

forming gas is the only furnace atmosphere that can make up the demerits of hydrogen and function

nearly 100% as if it were hydrogen gas. There are cases where forming gas cannot replace pure

hydrogen, but such cases are very rare. For almost all applications involved, forming gas atmosphere

will answer the purpose.

An ammonia cracker, NH3 Cracker or hydrogen generator is used for the production of forming gas.

Hydrogen and Nitrogen are

generated in a cost effective way in a volume ratio of 3 : 1 or in a weight ratio of 14 : 3. Capacities from

5m3/h to 60m3/h are available.

The NH3 is coming from bottles or from an ammonia tank. The ammonia gas is pre heated in a heat

exchanger and vaporizer and then cracked in the main furnace unit. The furnace is

electrically heated by special LGO heating elements.

The dissociation of ammonia gas NH3 takes place at a temperature of 920°C in the presence of a

special nickel catalyst in an electrically heated furnace.
2NH3-N2 + 3 H2
The cracked gas then passes the heat exchanger for cooling and for pre-heating the incoming gas. This way

and in combination with the low power consuming LGO heating

elements, it can be made sure that only a minimum of electricity has to be used for the cracking process.
