The hydrogen generator uses liquid ammonia as raw material, vaporizes in the vaporizer after being decompressed by the liquid ammonia pressure reducing valve and then enters the decomposing furnace. The decomposing furnace is equipped with activated nickel catalyst and decomposes at 800 ℃-850 ℃. After decomposition, the high-temperature gas exchanges heat with gaseous ammonia in the heat exchanger. The decomposed gas cools down. The gaseous ammonia recovers heat and heats up before entering the decomposing furnace for decomposition. At the same time, a mixture of 75% hydrogen and 25% ammonia was obtained.

The mixed gas generally needs to enter the gas purification (drying) system to remove residual moisture and other impurities. The dryer is generally set up two sets, one adsorbs the moisture and other impurities in the mixed gas, and the other desorbs the moisture and residual nitrogen in the heated state (usually at 300-350 ℃), so as to achieve regeneration and reuse. The effect.

Formula: clean cooked aluminum (sold in scrap shops, hammered tightly, the closer to the isolation plate, the better) flake alkali (sold in chemical shops), water (AI, NaOH, H2O), the reaction ratio of aluminum to alkali is about 1 to 1.8 (aluminum should be more), and water is generally fixed at 28-32kg.

 

Installation procedure: (first wrap the fuselage with single-layer cotton gauze) open each cover plate first, and distinguish the cover plate at the same time, and do not install it incorrectly! The safety valve can be pulled up to prevent death and loss of protection. The best host with wire and cart binding.
