Method and apparatus for treating wastes by gasification

An apparatus for treating wastes by gasification, said apparatus comprising:

• a fluidized-bed reactor for gasifying wastes at a relatively low temperature to produce gaseous material and char;
• and
• a high-temperature combustor for producing low calorific gas or medium calorific gas from said gaseous material and said char at a relatively high temperature.

An apparatus for treating wastes by gasification, said apparatus comprising:

• a revolving flow-type fluidized-bed reactor for gasifying wastes at a relatively low temperature ranging from 450 to 800.degree. C. to produce gaseous material and char;
• and
• a swirling-type high-temperature combustor for producing low calorific gas or medium calorific gas from said gaseous material and said char at a relatively high temperature of 1300.degree. C. or higher.

An apparatus for treating wastes by gasification, said apparatus comprising:

• a fluidized-bed reactor for gasifying wastes at a relatively low temperature;
• and
• a high-temperature combustor for producing combustible gas at a relatively high temperature gaseous material and char produced in said fluidized-bed reactor.
