Ammonia decomposition hydrogen production furnace uses industrial ammonia gas as raw material, and obtains hydrogen-nitrogen mixture under the action of catalyst. Manufacturing and glass manufacturers need a little bit, so today, Xiaobian will explain to you the working principle of ammonia decomposition hydrogen production furnace and its application field.
First, The working principle of ammonia decomposition hydrogen production furnace
1. Using liquid ammonia as raw material, after ammonia is cracked, 2.64Nm of mixed gas can be obtained per kilogram of liquid ammonia cracking, which contains 75% hydrogen and 25% nitrogen. The obtained gas contains less impurities (the water vapor in the impurities is about 2 g/m3, and the residual ammonia is about 1000ppm). After passing through the molecular sieve (UOP) adsorption purifier, the dew point of the gas can be reduced to below -60C, and the residual ammonia can be reduced. to below 3PPM.
2. Ammonia decomposition hydrogen production furnace can be used for bright annealing of non-ferrous metals, silicon steel, chromium steel and stainless steel and other metal materials and parts, decarburization treatment of silicon steel sheets, copper-based, iron-based powder metallurgy sintering, and metal parts of electric vacuum devices. Hydrogen treatment, protective sintering and sealing of semiconductor devices, raw material gas for hydrogen purification by diffusion of palladium alloy membrane, etc.
3. The raw material ammonia is easy to obtain, the price is low, and the raw material consumption is less. Ammonia cracking to produce protective gas has the advantages of low investment, small volume and high efficiency

Second, Working principle diagram of ammonia decomposition hydrogen production furnace
In order to fully decompose ammonia, the following conditions must be met:
1. Supply a large amount of heat in a timely and sufficient manner.
2. Better catalyst.
3. The purity of liquid ammonia is above 99.8%.

Third, Application fields of ammonia decomposition hydrogen production furnace:
Metal heat treatment: stainless steel strips, various precision steel strips, steel wires and other steels and alloys,
Protective atmosphere for annealing of copper tubes, copper wires, copper strips, etc.
Metal reduction: reduction atmosphere for tungsten and molybdenum reduction and iron powder reduction
Powder metallurgy: reducing protective atmosphere for iron-based and copper-based reduction
Others: protective gas in magnetic materials, special ceramics, diamond products, and cemented carbide.
