Gas-solid separation and pneumatic conveying in coal gas fluidized bed gasification
Thread Content
Gas-flow beds are now used in many industrial installations. During their operation, common problems include blockages that can occur when coal is transported pneumatically into the gasification furnace, as well as uneven distribution of coal. Additionally, too much dust may be carried along with the gas exiting the gasification furnace. How are these issues typically addressed?
Control the gasifier and furnace pressure. The volume and pressure of the gas used for transportation are important; coal powder needs to be dry and have a uniform particle size. The issue of coal powder being carried along with the gas relates mainly to the flow velocity of the gas stream. Equipment is also crucial – preventing air from getting trapped during material transfer is very important, as this aspect has many implications. It’s worth reading more professional books on this topic, as there are numerous solutions available
