From the article:
The gasification technology is now considered to be in an advanced stage of development. Hence there is huge expectation from the user industry for its application. The aim of this paper is focused on analysis of reduction chamber or zone for different changes in choke plate design. The choke plate itself is an integral part of reduction zone and thus analysis of reduction zone or choke plate is one and the same. For this purpose a 100 kW down draft biomass gasifier system is designed using empirical data and derived quantities. The changes made in choke plate include no. of nozzles, diameter of nozzle and nozzle inclination angle. In this paper airflow analysis, temperature distribution across the chamber and mass concentration of gasification products has been analyzed by CFD method using CFX 5.5.1 software.
