Experiment of Sulfur Removal in 1MW Poly-Generation System with Air Gasification and Combustion Combined

摘要

An experimental research on sulfur transformation and removal during coal partial gasification and combustion was accomplished in a 1 MW poly-generation system. Air gasification was adopted in the system. The effects of rising temperature on various components are different i.e. formation of CO and H₂S are enhanced while H₂, CO₂ and hydrocarbons are reduced. Limestone catalysis contributes to increase all the components release mentioned above but H₂S. At 900-950°C, promoting temperature may bring more contribution than increasing limestone in a certain extent. It is hard to study the reactions of sulfur release and transformation quantitatively in such conditions that materials experience respectively gasification and combustion in a poly-generation system.
