Numerical Simulation of Coal Oil Water Slurry Gasification Process in New-Type Coal Water Slurry Gasifier
The gasification process of coal oil water (COW) slurry in new-type coal water slurry(CWS) gasification furnace was studied with numerical simulation method. The temperature and concentration fields were obtained for the gasification furnace. The simulated results showed that the gasification effect of the new-type coal water slurry gasification is better than the common coal water slurry gasification. In the new-type gasification furnace, the average temperature is slightly increased and the carbon translative ratio is increased by 1.81%. The effective component (CO+H2) in coal gas at the outlet of the furnace is increased by 10.58%, and the concentration of CO2 and H2O is greatly decreased. The H2O dissolution ratio is greatly increased and the gasification effect is obviously better that that of the common coal water slurry.
