Abstract
The gasification process of petroleum-coke coal water slurry in a new-type coal water slurry gasification furnace has been simulated. The temperature distribution in the coal water slurry furnace and the concentration distribution of the gasified products have been studied. The simulated results showed that the gasification effect of the new-type coal water slury gasification is better than the common coal water slurry gasification. In the new-type gasification furnace the average temperature and the carbon translative ratio is slightly increased. The effective component (CO+H <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> ) in coal gas at the outlet of the furnace is increased by 7.91%, and the concentration of CO <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> and H <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> O is greatly decreased. The H <inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> O dissolution ratio is greatly increased and the oxygen used for unit mass coal water slurry gasification is decreased by 6%.
