This paper reports the experimental results obtained on a two-sage gasification pilot plant base on the NOTAR® concept. The facility is described together with the main adjustable parameters. Among them, the air ratio determining the amount of air introduced in the pyrolyzer is further studied. Two experimental campaigns show that the air ratio has an influence on the gas quality. First, the upper and lower limits for the ratio are examined based on the gas...
