Shell’s furnace wall structure is urgently needed; thank you very much
Thread Content
I now need to draw a schematic diagram of the wall structure for a Shell-type furnace, but I know very little about this topic. I only know that the water-cooled walls are equipped with clamping nails and coated with a refractory layer; during operation, slag solidifies on this refractory layer, with liquid slag flowing over the solid slag (in a process of slag resisting slag). I’m not sure if this understanding is correct. But what is the structure between the water wall and the shell? I would be extremely grateful if experts in this field could provide some guidance.
There is a macroscopic cavity between the water wall and the pressure vessel
That’s Shell’s secret; it can’t be given to you
That space is called an annular space. The annular space is connected to the furnace chamber of the gasifier through a balance air passage in order to balance the pressure between them, as the water-cooled walls can withstand heat but not high pressures
