W radiant tube is a radiant tube that ensures the controllability of the atmosphere in the furnace. Easy to control, install and maintain temperature, easy to seal.
Since there is no muffle tank in the furnace, the furnace capacity is expanded, the production capacity is improved, the heating efficiency and production efficiency are improved, and materials are saved. It is a good partner in the field of industrial processing.
W-shaped radiant tubes have higher thermal efficiency, but their wall temperature distribution and service life are worse than U-shaped radiant tubes.
Radiant tubes are a type of exhaust gas recirculation. O-shaped radiant tubes have a complex structure, are difficult to manufacture, and have fewer practical applications. They are complex to manufacture, have high costs, have uneven surface temperature distribution, and have a shorter service life than U-shaped radiant tubes, so they have fewer practical applications.
In fact, casing radiant tubes with waste heat recovery devices and U-shaped radiant tubes with waste heat recovery devices are the most widely used.
In order to improve the thermal efficiency of the radiant tube, the most direct method is to increase the length of the radiant tube and increase the flow time of the flue gas in the radiant tube, so that the flue gas and the radiant tube can fully exchange heat.
However, if the length of the radiant tube is too long, it will cause problems in strength, stiffness, manufacturing and installation, etc., which will affect the service life of the radiant tube. Subsequently, the structure of the burner was continuously improved to fully mix and burn the gas and combustion air, thereby improving the thermal efficiency of the radiant tube.
Conventionally, 1.4852, 2.4879 and other materials are used.
