An oxygen enriched air blown pilot scale pressurized fluidized bed refractory lined gasifier

An oxygen enriched air blown pilot scale pressurized fluidized bed refractory lined gasifier system comprising:

• a cylindrical vessel of two different diameters;
• a gaseous reactant generation and supply system with the provision of preheating and thorough mixing before entering into the gasifier;
• plurality perforation removable conical distributors;
• an air plenum;
• differential pressure measurement instrument across the distributor and bed;
• a fuel feeding system with a feed hopper arrangement comprising of a rotary feeder and a screw feeder;
• plurality of feeding nozzles;
• an inclined feed lines with the provision of pneumatic conveying of feed materials;
• an ash withdrawal system consisting of a rotary extractor;
• a purging system;
• a rupture disc/safety valve;
• a cyclone separator;
• a quench column;
• a ventury scrubber;
• a knockout drum;
• a settling tank;
• a gas sampling port;
• a flare stack;
• and
• a nitrogen generator,
• wherein nitrogen flushing comprises a control panel and data acquisition section operative to store and display data including process parameters enabling a wide range of operational flexibility with respect to pressure, temperature, feedstock, feed rate, gaseous reactant, residence time, particle size and particle density.
