Product Gas Measurement in Fluidized Bed Steam Gasification of Rice Husks
Original language description
As the common agricultural feedstock, rice husks can be a sustainable biofuel option with significant cal-orific value (16-17 MJ/kg) and ash deforming temperature recorded above 1450°C. The research determines product gas on the 100 kW dual fluidized bed steam gasifier performance of rice husks pellets at temperatures between 760 and 810°C. Pure steam was used as a gasification agent at a ratio of 0.87 kgsteam /kgfuel, db. Calcite with mainly CaCO3 in compositions was used as bed material for the reactor. Significant H2 content was de-termined with high quantity of CO2 and CH4 in product gas, while CO level was relatively low. Due to the considerable sulfur and nitrogen contents of this fuel, values of the impurities NH3 and H2S in the producer gas was detected. It is also shown that the majority of sulfur was released in the gasification zone and, therefore, no further cleaning of the flue gas was necessary. Ethylene, ethane and propane were also formed but only in amounts below 2 vol.-% dry gas. Specific product gas yield reached 1.2 Nm3db /kgfuel,db,af
