The issue of raw gas temperature
Thread Content
How can the temperature of raw gas be increased, and what factors influence it?
What type of vaporization furnace is it? The operation procedures vary slightly depending on the furnace model, so please specify! Is it because the temperature at the exit of the furnace is too low, or is there some other reason? Why does it need to be increased? What is the current temperature at the exit of the furnace?
It refers to the low temperature of the raw gas before the shift reaction; currently it is around 180°C, and this affects the steam-to-gas ratio in the shift reaction.
This is related to the specific process: the temperature of the raw coal gas in the water-coal slurry system is influenced by the amount of water used for cooling as well as the amount of water in the carbon cleaning tower. In Shell gasifiers, it is related to the circulating cooling gas, and the temperature of the raw coal gas is controlled based on the water-to-gas ratio in the downstream processing units.
It can increase the temperature of the washing water, boost the oxygen level, raise the furnace temperature, and reduce the amount of cold desalinated water that needs to be added
Different gasification processes use various methods to increase the steam-to-gas ratio, but the underlying principle is the same: to ensure that more heat is carried over to the syngas side, thereby raising the temperature of the subsequent systems and reducing the amount of water that needs to be circulated.
I’m a beginner; I’m not sure whether increasing the temperature of the raw gas during conversion affects its dust content
Adjusting the gas-to-vapor ratio is a basic operation in gasification
This is well adjustable in gasification; the temperature of the raw gas mainly affects the water-to-gas ratio
