Optimization of the performance of down-draft biomass

producer gas which in turn prefer down-draft gasifier, as down-draft gasifier generally produce low particulate and low-tar gas. This study was carried out to study the effects of throat diameter and air-fuel ratio on the gasifier performance. Further the study aimed at identifying practical difficulties on the operation of downdraft gasifiers.

Down Draft gasifiers - ascentbioenergy.com

Downdraft wood Gasifier requires wood chips, biomass briquettes or wood like agro-residues (such as stems, stalks). If fuel flexibility is required and need for fuel switching (say from biomass to coal or from one biomass to another) is anticipated, the updraft gasifier would be suitable. For gasification of coal, updraft gasifier is suitable.

Wood Gasification Boilers | Tarm Biomass

A wood gasification boiler is a heating boiler with a unique combustion design often called downdraft or two-stage combustion. It uses a controlled amount of oxygen injected into the firebox in two distinct zones to burn wood efficiently. Unlike traditional wood boilers, gasification boilers are designed to burn smoke, resulting in more
