Modeling & Simulation of Biomass Gasifier: Effect of Oxygen Enrichment and Steam to Air Ratio
نویسندگان
چکیده
Gasification is one of the efficient ways to convert the energy embedded in biomass. Understanding of the effect of a few key parameters such as oxygen enrichment and preheating of air on major design parameters is crucial in designing of a biomass gasifier. In the present study, equilibrium modeling is used to predict the performance of a downdraft gasifier. The composition of producer gas and, hence, the calorific values are determined. The effects of oxygen enrichment of air, preheating of air, and steam to air ratio on gas composition, reaction temperature and calorific values are investigated. The calorific values of the producer gas increase as the oxygen fraction increases and also as the steam to air ratio increases.

Rubber wood (Ficus elastica) is one the biomass waste that can be used as raw material for a gasification process and has a calorific value of 4,069 cal/gram. Gasification is a process to convert a solid fuel to syngas (CO, CH4, and H2) through a combustion process using limited air between 20% to 40% of air stoichiometry. Depending on the direction of airflow, the gasifiers are classified as u...
