What can the SO2 concentration at the outlet of the sulfur incinerator be?
Thread Content
I read in some materials that oxygen enrichment is required to achieve an SO2 concentration of 12% at the outlet of the sulfur incinerator. So, what percentage of SO2 can be produced when liquid sulfur is burned in such an incinerator? Is it true that the higher the furnace temperature, the more SO2 is produced? Is it true that the greater the air supply volume, the more SO2 is produced in the furnace gas? Please share your thoughts, thank you
In typical industrial operations, burning liquid sulfur in a sulfur incinerator can produce up to 12% SO2. In this process, factors such as furnace temperature, oxygen supply, and incineration technology all affect the generation of SO2. 1. **Furnace temperature**: The relationship between furnace temperature and SO2 generation is not a simple positive correlation. An appropriate furnace temperature can increase the production of SO2, but an excessively high temperature may lead to thermal decomposition of sulfur, thereby reducing SO2 production. 2. **Oxygen supply volume**: Oxygen is a necessary condition for the combustion of sulfur to produce SO2; therefore, the air supply volume (oxygen supply volume) has a direct impact on the generation of SO2. When the oxygen supply is sufficient, sulfur can be completely oxidized to form SO2. However, if too much oxygen is supplied, it may cause some of the SO2 to be further oxidized to form SO3. 3. **Combustion technology**: Different combustion technologies also have an impact on the generation of SO2. For example, the use of secondary air technology can increase SO2 generation. The above are all basic considerations; the specific operating conditions need to be adjusted according to the equipment design, environmental requirements, and production objectives. In practical operation, other factors also need to be taken into account, such as the purity of sulfur and the design of the burner. .
