Description

Technical Field

[0001] The utility model relates to the technical field related to catalytic furnaces, in particular to a catalytic furnace for catalytic combustion. Background Art

[0002] A catalytic combustion furnace uses a catalyst to oxidize and decompose organic gases and hydrocarbons at a relatively low temperature. Its operating principle is that when high-temperature fuel gas passes through the purification device, the oxygen in it is consumed, releasing a large amount of heat. This heat is absorbed by the gas heater and transferred to the cool metal surface, which then transfers it to the heating element. The catalyst causes the combustible substances in the gas to react chemically with oxygen in the air, oxidizing them into harmless gases such as water and carbon dioxide, which are then discharged from the furnace. The reaction products are then recycled as raw materials for the next batch of fuel.
