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.

本研究所呈现的数据系基于城市固体废物颗粒的下降式气化实验数据。数据包含两个文件，其一为经处理后的实验数据的电子表格文件；其二为包含一系列实验图像及处理数据图表的演示文稿。研究旨在通过将单级气化器改进为多级气化器，通过向裂解区添加空气并预热空气，以提升合成气的热值并降低焦油含量。研究调查了当量比、空气比、预热空气温度等因素的影响。当量比增加时，可燃气体及低热值成分有所减少。在当量比与空气比之间，对气化性能影响最为显著的是空气比或向裂解区添加空气。本研究的结果可应用于利用预热空气对多级气化器进行优化。
