What are the disadvantages of adding coal under normal pressure to the gasification furnace?
Thread Content
There are indeed many benefits to adding coal under normal pressure, so I won’t list them all here. I would like to ask how much impact adding coal under normal pressure has on the gasification furnace itself, to see if the benefits outweigh the disadvantages or the disadvantages outweigh the benefits.
Why don't you tell me clearly what type of furnace you are asking about?
The disadvantage is that the pressure difference between the material and the system is too large, causing the material entering the furnace to flow too fast, which may cause erosion.
It should be impossible to add coal under normal pressure. Because the ignition burner must pressurize the gasifier to 1MP, I personally think it should not be possible to add coal under normal pressure.
Brother, you have little knowledge. It should be SUB boost, which can be controlled and can be cast when it is a little over 3 kilograms.
The biggest obstacle to SCGP normal pressure coal injection is that the quenching air volume cannot meet the requirements. 1. If the single-stage cantilever centrifugal unit is imported, its normal pressure startup will cause its axial displacement to be too large. 2. The measurement of the single-stage cantilever centrifugal unit under low pressure (such as 0.3MPa) can be estimated by extending the performance curve, which is far from the quenching air volume required when coal is added. 3. This point of view may be due to lack of confidence in SUB: lol
Tell me about the issues to pay attention to when driving the ash-melting polygasifier
