With the increasing market demand of SiC radiant tubes, efforts must be made from these components in order to improve the quality of SiC radiant tubes. Only by ensuring the good performance of the components can the performance of SiC radiant tubes be improved. Now let's introduce it to you.
1. By adjusting the ratio of combustion gas and combustion supporting air, the O2 content in incineration waste gas is controlled below 2. Under the maintenance of nitrogen, the radiation tube will be corroded due to the effect of excessive oxygen oxidation and nitriding.
2. The action of gas pressure control valve and air pressure control valve should be sensitive and not lag behind, so as to ensure the gas pressure and air pressure to ensure complete and stable incineration.
3. When SiC radiant tube is used, the heat exchanger of combustion supporting air shall not leak, so as to prevent the air from being pumped away by the exhaust fan, which will affect the mixed incineration share of gas and air.
4. The connecting flange and sealing function of the heat exchanger are good, so the outside cold air can not enter. The temperature of combustion supporting air should be improved as much as possible.
5. If the conditions and funds permit, large heat exchanger should be installed to preheat the air for the first time by using the waste heat discharged outside the plant (up to 390 ℃), and then the air will be preheated for the second time after entering the heat exchanger in the radiant tube of the burner, so as to improve the temperature of combustion supporting air.
6. When the temperature of SiC radiant tube is 400 ℃ (furnace temperature), it is strictly forbidden to open the furnace cover and disassemble the burner and heat exchanger to prevent the high temperature radiant tube from shortening and forming cracks when encountering cold air.
