Oxy-steam biomass gasificaton system for generating hydrogen rich syngas

A biomass gasification system (200) comprising:

• a gasification reactor (102) comprising an inlet (104), an outlet (106) and side walls (108) configured to gasify a biomass feedstock into a hydrogen rich syngas gas;
• a plurality of injectors (202) protruding inside the gasification reactor (102), wherein the plurality of injectors (102) are inclined at an angle with respect to the side walls (108), wherein the plurality of injectors (202) are positioned circumferentially around the gasification reactor (102) and along the lengthwise extension of the side walls of the gasification reactor (102);
• a plurality of thermocouples (112) coupled along the length of the gasification reactor (102) to monitor the temperature of the gasification reactor (102);
• and
• an ignition nozzle (114) located at a bottom end of the gasification reactor (102) for igniting the biomass feedstock.

A method (300) for converting a biomass feedstock into a hydrogen rich syngas using a biomass gasification system (100, 200), wherein the method (300) comprises:

• igniting (302) a charcoal bed through an ignition nozzle (114) positioned at a bottom end of the biomass gasification system (100, 200), wherein the biomass gasification system (100) comprises:
• a gasification reactor (102) comprising an inlet (104), an outlet (106), and side walls (108) configured to gasify the biomass feedstock into a hydrogen rich syngas;
• a plurality of injectors (110, 202) positioned circumferentially around the gasification reactor (102) and along the lengthwise extension of the side walls (108) of the gasification reactor (102), wherein a first set of injectors (110) from the plurality of injectors are protruding radially inside the gasification reactor (102) and a second set of injectors (202) are inclined at an angle with respect to the side walls (108);
• injecting (304) a gasification agent in the gasification reactor (102) through the plurality of injectors (110, 202) disposed along the length of the gasification reactor (102);
• and
• collecting (306) the hydrogen rich syngas from the outlet (106) of the gasification reactor (102), wherein the steam to biomass ratio is varied in a range of 2.7 to 3.5 for increasing the yield of hydrogen.
