The issue of using some methane as a gasifying agent
Thread Content
As the title suggests, what are the problems associated with using carbon dioxide containing methane (at a concentration of over 10% by volume) as a gasifying agent in pressurized fixed-bed gasification?
Based on the ratio of the two, changes in the temperature of the oxidation zone occur.
Based on the ratio of the two, the temperature in the oxidation zone of the fixed-bed reactor will change； Fluidized bed and gas-fluidized bed systems experience temperature variations inside the furnace.
Temperature changes are normal; what are the safety issues that need to be addressed?
Carbon dioxide containing methane (10% v or more) – what kind of gas is this? Is it over 10% methane? Is it still over 10% carbon dioxide?
Exhaust gas with carbon dioxide recovered. Fixed-bed gasification results in high methane content in the gas.
Is methane over 10%? Is carbon dioxide still over 10%?
Is methane over 10%? Is carbon dioxide still over 10%?
With such a high concentration, it can be used directly as fuel gas; there is no need to return it to the gas furnace as a gasifying agent, as this could otherwise cause deflagration.
