The main structure of the W-shaped radiant tube is composed of the main straight tube, elbow, flange, support plate, etc., and it needs to be installed in the furnace with the burner and heat exchanger.
Usually, in the natural gas system, the W-type radiant tube in the heating furnace is often used. There are W-type radiant tubes in the heating section and W-type radiant tubes in the soaking section.
During the installation process, a corresponding burner is often organized at one end of the radiant tube in the furnace, and then a suitable heat exchanger is equipped at the other end.
After that, it will be connected with the gas pipeline through the flange, and there is a positioning plate on the tube that matches the furnace shell.
After the installation is completed, we also need to carry out proper sealing treatment to ensure its use effect.
The basic components of the W-type radiant tube are the radiant tube body and the burner.
High-efficiency radiant tubes often have waste heat recovery devices.
The key component of the radiant tube is the tube body, which radiates the heat released by fuel combustion to the heated material.
The core device of the W-shaped radiant tube heating technology is a gas burner. The radiant tube burns and heats the incoming fuel through the burner.
The power of the burner controls the temperature distribution of the wall, thereby affecting the power, thermal efficiency and life of the radiant tube. In the whole device of the gas radiant tube,
the important part to improve the thermal efficiency of the gas radiant tube is the waste heat recovery device. The radiant tube without flue gas waste heat recovery device has large exhaust loss and low thermal efficiency.
A waste heat recovery device is installed at the smoke exhaust end of the radiant tube to preheat the fuel or gas-supporting air, which reduces the exhaust gas temperature and reduces environmental pollution while improving efficiency.
