Detailed introduction of industrial furnace equipment for ammonia decomposition hydrogen production
1, Equipment Overview
The ammonia decomposition hydrogen production industrial furnace is a device that decomposes ammonia gas (NH3) into hydrogen gas (H ₂) and nitrogen gas (N ₂) through heating. It is widely used in metal heat treatment, electronics, chemical industry, glass and other fields, providing high-purity hydrogen gas for the production process.
2, Working principle
The working principle of the ammonia decomposition hydrogen production industrial furnace is based on the decomposition reaction of ammonia gas under certain temperature and catalyst action. When ammonia enters the reaction furnace equipped with a catalyst, it decomposes into hydrogen and nitrogen under high temperature conditions of 700-850 ℃. The chemical reaction equation is:
