Data Set for Experimental Analysis Modified Downdraft Gasifier with Variation of Air Input and Preheat Air Temperature

The data presented is data from gasification experiments using municipal solid waste pellet-based downdraft gasifier. there are two files, one file in the form of a spreadsheet whose contents are experimental data that has been processed. the second data is in the form of a powerpoint with a series of experimental images and graphs of processed data. The aim of this research are to Increasing the syngas heating value and reduce the tar content by modifying the single-stage gasifier to be multi-stage by adding air to the pyrolysis zone and preheat air. The influence of equivalent ratio, air ratio, preheat air temperature was investigated. When the equivalent ratio is increased, the flammable gas and LHV components decrease. Between the equivalent ratio and the Air ratio, the most effective effect on gasification performance is the air ratio or adding air to the pyrolysis zone. The results of this study can be used for multi-stage gasifier optimization using preheat air.
