One of the important technical indicators during the use of radiation tubes is the uniformity of surface temperature along the length direction of gas radiation tubes. To meet this requirement, the mixing intensity of gas and air in the radiation tube should be appropriate. When the heat load of the radiation tube increases, the suction force of the pipeline should be increased; Otherwise, the suction force of the pipeline should be reduced; When the preheating temperature of the air increases, the exhaust suction of the radiation tube should be increased or the gas supply should be appropriately reduced to ensure that the wall temperature of the tube remains basically unchanged and extend the service life of the radiation tube; The high point of pipeline wall temperature should be frequently adjusted by adjusting the exhaust suction of the pipeline to avoid the long-term impact of local high temperature in the pipeline.
The main technology and performance of radiation pipelines:
Cold resistance error range of electric heating wire ≤ 3%
The insulation resistance between the outer protective tube and the heating wire is greater than 2. MΩ
Outer diameter of heating tube: various specifications ranging from 60mm to 300mm
Heating power: from 2KW/unit to 24KW units of various specifications
Heating tube outer tube length: 800. Various specifications ranging from mm to 2800mm
External wall thickness of radiation tube: 1.5mm to 16mm in various specifications.
