Water wall and refractory bricks
Thread Content
Why does the Shell gasifier use water-cooled walls instead of refractory bricks? Is it to produce steam? Is it still because the refractory bricks burn out easily?
It seems that someone said yesterday that the cost is too high; water cooling systems can last 5 to 6 years, while refractory bricks only last 1 to 2 years, and they are also expensive.
Yes! Mainly considering cost and lifespan
If it comes to energy conversion, it seems to be a different matter. It would be best to investigate the reasons for the short service life of refractory bricks. Such as the physicochemical properties of the fuel? Selection of refractory materials? ?
Isn’t the water wall meant to increase the heat exchange area? I don’t know, completely confused
