Apparatus for treating waste material and a product gas

An apparatus for treating waste material including organic components and radioactive agents to form a treated gaseous material, the apparatus comprising:

• a fluidized bed reactor configured to gasify the waste material including organic components and radioactive agents from the group consisting of resins, clothes, contaminated wood, and contaminated vegetable matter, wherein the radioactive agents are low-level and/or medium-level radioactive agents, using air at an air ratio greater than zero and less than 1 at temperatures between 600-950° C. to form a gaseous material,
• a water quenching device configured to quench the gaseous material to temperature which is between 300-500° C. after cooling by water quenching to form a cooled gaseous material,
• a gas cleaning device configured to remove a solid fraction by filtration carried out at temperature between 300-500° C. in at least one filtration device, including removing the radioactive agents, from the cooled gaseous material and to form a treated gaseous material, and
• a gas scrubbing device configured to remove sulphur by scrubbing from the treated gaseous material after the filtration.
