The transportation of pulverized coal in dry powder gasification
Thread Content
1. What are the specific states of coal and gas in the pulverized coal transportation process under various major dry coal gasification processes? 2. Comparison of gas consumption for coal powder transportation. 3. Comparison of conveying control methods.
Slurry transport: transports the maximum amount of coal using the minimum amount of air; density requirements apply, and control can be achieved through angle valves
Pulverized coal is pressurized and conveyed in a dense phase; the gas primarily serves to fluidize the coal. Pulverized coal is transferred from a high-pressure storage tank to a low-pressure gasifier, with the density and velocity needing to be maintained.
