Gas composition at the outlet of a four-nozzle gasification furnace
Thread Content
In production, I see them controlling the carbon dioxide level at the outlet of the gasification furnace, and adjusting parameters such as the furnace temperature based on that carbon dioxide level. What is the basis for such operations? What can the carbon dioxide content reveal?

To reduce the production of carbon dioxide, it is necessary to adjust the oxygen-coal ratio, which in turn affects the furnace temperature.
The carbon dioxide and methane concentrations are among the key indicators for determining the temperature in the furnace of a gasification unit
A high CO2 level indicates a high oxygen-to-coal ratio, excessive combustion, and a high furnace temperature
There is only a limited amount of carbon; when there’s more carbon dioxide, there’s less carbon monoxide. Moreover, the oxygen level increases, which allows for more complete combustion, resulting in higher temperatures. There’s less methane and more hydrogen. It is a series of reactions
