Installation of O2 and steam injection system inside gasifier can be expected to improve syngas quality, all at once N2 content is decreasing, with the result of H2/CO ratio >1 that will produced liquid product optimally. The mixed air+steam injection by steam valve variation opening of ¼ as well as ½ rotation still being possible gasifier operation at temperature condition higher than 700oC. Mixed air+steam injection showed more easily flameable than air injection only, so this mean H2content in the syngas will be increasing.
