Ammonia Cracker with Purifier for Metal Powder Annealing

Ammonia Cracker with Purifier for Metal Powder Metallurgy Working Principle:

Ammonia Cracker for generation of forming gas,which can be used for metal powder annealing, takes liquid ammonia as the source. Having being vaporized, the ammonia then is heated and decomposes into the forming gas with 25% nitrogen and 75% hydrogen under the action of catalyst. In theory, one Kg of ammonia can produce 2.64 Nm3 mixed gas.
Our equipment possesses the characteristics and advantages of compact structure, low space requirement, small investment, simple operation, low energy consumption and long service life.
Supported by and combined with the XRFC series purifying equipment of our company, the higher purity shielding gas can be obtained. However, the ammonia as source must be of first class or above, to be exact, the purity of the source ammonia must be no less than 99.8%.

Properties and Characteristics:
1) Save water and electricity: No water is used in the the ammonia decomposing process, thus save water effectively; The heat generated from the decomposition reaction is used to preheat the ammonia so as to save the electricity.
2) Resistance wire can be replaced quickly: It can be replaced only within a few minutes, no need to stop the gas production process. Therefore, the case of shutting down the furnace to cool down and then opening the furnace to replace the resistance wire is avoided.
3) Low investment and convenient use: Matured technology, compact structure, low space requirement and no need of construction investment, easy operation, low price, high economy to extract the pure hydrogen; In order to generate hydrogen on spot, the only thing to do is to connect power and gas source.
4) Wide application scope: It can satisfy the need of most hydrogen use, especially in the dominating fields of heat treatment, powder metallurgy, electronics and so on.
5) Low operation cost: Less investment, liquid ammonia as source is cheap, low energy consumption, high efficiency, low operation cost; It is the most economical source of the mixed protective atmosphere of nitrogen and hydrogen.       FAQ   FAQ What is the material of the electric furnace of the ammonia cracker?
