Working principle:
The ammonia gas is heated to a certain temperature after gasification. Under the action of catalyst, ammonia is decomposed into hydrogen-nitrogen mixture gas. The chemical equation of ammonia decomposition is as follows: 2NH3 = 3H2 + N2-22080 calories, that is, 1 kg of liquid ammonia under standard conditions.Complete decomposition can produce a mixture of 2.64Nm hydrogen and nitrogen. According to the chemical equation, the decomposition gas consists of 75% H2 and 25% N2. The decomposition pressure is determined by the pressure of imported ammonia, and the pressure difference is less than 0.05 Pa. After heat exchange and cooling,the decomposed mixture gas enters the dryer to participate in the deep adsorption drying of ammonia and trace water, thus producing pure hydrogen-nitrogen mixture.
Durable Efficient Energy-saving
1、Precise temperature control
Imported intelligent temperature control instrument is adopted. The accuracy of temperature control and the incidence of faults are low.
2、Special catalyst
Special catalyst produced by Southwest Chemical Institute is used. It is not easy to pulverize.
3、Heating components
Using high quality Cr20Ni80 electric heating flat strip.
4、Energy saving
Thicker insulation layer is adopted. It has slow heat dissipation, non-hot outside wall of heating furnace and high energy saving efficiency.
5、long life
Cr25Ni20 heat-resistant stainless steel tube without oxide skin at 900 C is used as decomposition furnace gallbladder material. Inconel 600 tube or Cr25Ni20 heat-resistant stainless steel tube with double and thicker structure is used as ammonia feeding pipe, i.e. ammonia distribution pipe, with long service life.
