Error issues in coal gasification ASPEN simulation
Thread Content
When using ASPEN to perform mathematical simulations of coal gasification, it was found that the results of generating enthalpy data were very different between those generated by BOIE correlation and manual input. The high calorific value of coal on a dry basis that I manually entered is 29.4MJ/kg. Haiyou, please explain why this is? At the same time, I used ready-made calculation examples in the literature. When other conditions remain unchanged, if the BOIE correlation calculation is used, the gasifier outlet temperature is 1700 degrees, which is obviously too high. If calculated using manually entered data, the gasifier outlet temperature is only 1100 degrees.
This requires reading more relevant literature, especially the applicable scope of these sets of correlations.
