Project Objectives & Task List
Objective:
? Modularize gasifier and standardize the burner design with a focus on modularization.
? Investigate the effect of water quench on gas composition, such as the increase in H2 due to the water gas shift (WGS) reaction.
? Modify UK CAER's 1 TPD coal OMB gasifier to form a staged gasification simply by replacing the existing camera monitor with a burner at the top of the gasifier.
? Task 1: Project Management and Planning ? Task 2: Construction of the Staged-OMB Gasifier ? Task 3: Parametric Study of Staged-OMB ? Task 4: Fuel Flexibility with Fuel Blend ? Task 5: In-situ Water Gas Shift (WGS) Development ? Task 6: Burner Testing ? Task 7: 3-D Simulation of Staged-OMB Gasifier and
Burner Effect ? Task 8: Technical and Economic Analysis
