Three-stage gasification is a method to overcome gasification disadvantages like high syngas tar content and low energy content, by introducing additional air intake into pyrolysis, oxidation, and reduction zones of gasification process. Three-stage gasification can be used only with precise air intake ratio (AR) that can maximize the performance of gasification in terms of cold-gas efficiency (CGE) and tar content. An experiment was conducted to find the precise AR variation to maximize gasification performance using several AR variations. The results indicate that by using precise AR variation, the performance of gasification system can be improved significantly. After experimenting with the final syngas samples, results show that CGE improved from 56.82% in single-stage AR (0;10;0) to 67.58% using AR variation 1;7;2, while tar content was minimized from initially 135.18 to 73.56 mg/Nm3. These results show that this gasification system has considerable potential for implementation in widely various ICE engine projects.
