A comprehensive three-dimensional numerical model is developed for simulation of the industrial opposed multiburner (OMB) coal–water slurry (CWS) entrained flow gasifier. The CWS gasification process divided into several submodels, including water evaporation, coal pyrolysis, and homogeneous heterogeneous char reactions. "effectiveness factor" method used to extrapolate intrinsic reactivity data gasifier conditions. Numerical simulations with proposed models are performed on OMB gasifier,...

High-pressure differential liquid-solid two-phase flow is widely used in the chemical industry, energy, and power fields. In this study, a multistage segmental throttling orifice pressure-reducing pipe was developed to address bridging risk erosion challenges associated with batch slag discharge coal gasification. Ultrasonic technology evaluate distribution inside establish mechanism. The research results demonstrate rapid increase pressure drop of rising rate, indicating its high-pressure...

Abstract The flow distribution is of significance to the fuel cell performance and durability, which has been studied from a theoretical practical level in this work. transverse‐flow‐control‐based mechanism behind processes revealed. core lies reasonable generation transverse flow, are prerequisite co‐requisite for homogeneity. For dual purpose, novel design combined‐mesh‐type zone proposed incorporating central horizontal meshes lateral vertical meshes. philosophy methodology clarified....

Information on luminescence of the excited-state radicals is significance for spectrometer-based diagnostics practical diffusion flames. In this paper, emission spectrometry was applied to detect distribution characteristics three (OH*, CH*, and C2*) in CH4/O2 co-flow jet flames with relatively high flow velocities (66 m/s CH4 18 O2/N2), which basis rationalize chemiluminescence flame gasification combustion processes. This method allowed online measurement intensity Results showed that...

Molecular refining is a concept and technology that recognizes optimizes the oil process from molecular level by aiming to enhance value of each molecule achieve high-value-added transformation products into chemicals materials. The structure-oriented lumping (SOL) method one methods for refining. SOL can predict physical chemical properties petroleum fractions on basis their structure composition simulate behavior under different reaction conditions. This has been successfully applied...
