Description

TECHNICAL FIELD

[0001] The utility model relates to the related technical field of catalytic furnace, especially to a catalytic furnace of sufficient reaction. BACKGROUND

[0002] The catalytic combustion furnace is a device for oxidizing and decomposing organic gas and hydrocarbon at a lower temperature by using a catalyst, and its working principle is that when high-temperature fuel gas passes through a purification device, oxygen in the fuel gas is consumed, and a large amount of heat is released. The heat is absorbed by a fuel gas heater and transferred to a low-temperature metal surface, and then transferred to a heating element from the metal surface. Due to the action of the catalyst, the combustible substances in the gas and the oxygen in the air react chemically to be oxidized into harmless gases such as water and carbon dioxide, which are discharged out of the furnace; and the reaction products become raw materials for the next batch of fuel for recycling.
