Abstract:A 2000 t/day HNCERI
(Huaneng Clean Energy Research Institute) entrained-flow
pulverized coal gasifier suffers from the problem of a high ash–slag
ratio. An appropriate bias angle of the burners is the key to solve
this issue for the gasifier with a specific structure. A random pore
model considering bulk and pore diffusion effects was extended by
user-defined function to describe the gasification reactions. The
simulation of the gas flow and char gasification characteristics under
different bias angles (0, 1.5… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
