Including dairy biomass (DB) as feedstock in gasification processes for locally based power generation could mitigate the environmental impact from DB produced in large US farms (56 million dry tons per year) and fossil-fuels emissions, since biomass is a CO(2) neutral fuel. The current paper presents experimental results obtained from adiabatic, fixed bed gasification of DB using air and steam as oxidizers. The effect of equivalence ratio (ER) and steam to fuel ratio (S:F) ratio on temperature pro. le, gas composition (CO, CO(2), H(2), N(2), CH(4), and C(2)H(6)), gross heating value (HHV) and energy conversion efficiency (ECE) are discussed. The results show that the peak temperature (T(peak)), ECE, and CO decrease and H(2) and CO(2) increase with increase in ER; the increase in S: F at same ER increases H(2), CO(2), CH(4), HHV, and ECE, and decreases CO.
