How do the gas components change in a gasifier under low gas flow rates?
Thread Content
During the furnace switching process in the gasification unit, with two units in operation and one as a backup, there is a period during which all three units are running simultaneously. This leads to insufficient oxygen supply, causing the gasification units to operate at reduced capacity. How will the composition of the gases produced during gasification change in such situations? I would appreciate guidance from those with more experience Also, do the gas components vary depending on the different gasification methods?
Low-load operation can be compared with slag hole blockage under full-load operation; the CO content increases while other parameters decrease
During the furnace inversion process, an operating gasification furnace operates at half capacity; otherwise, the oxygen flow rate cannot be established. Once the furnace is started and gas supply is established, the gasification furnace that is ready to stop will cease operating as well; therefore, there is still enough oxygen available
The flow rate decreased, the residence time increased, and CO levels rose. The load difference between these two furnaces is around 5,000 oxygen units; obviously, the CO level is higher in the furnace with the lower load. This is my personal opinion; it may not be correct and is for reference only.
