Abstract
Provided is a combustible waste treatment method capable of suppressing the falling rate of even combustible waste having relatively poor combustibility into a clinker during combustion. The combustible waste treatment method includes: blowing first combustible waste having flammability into a kiln from a first waste burner disposed at a position vertically above a main burner blowing main fuel; and blowing second combustible waste having flame retardancy into the kiln from a second waste burner disposed at a position vertically above the first waste burner.
Claims8
A combustible waste treatment method comprising:
- blowing first combustible waste having flammability into a kiln from a first waste burner disposed at a position vertically above a main burner blowing main fuel;
- and
- blowing second combustible waste having flame retardancy into the kiln from a second waste burner disposed at a position vertically above the first waste burner,
- wherein the second combustible waste is waste which satisfies at least one condition selected from:
- a resin ratio of less than 60% by mass, a fuel ratio of more than 1.0, and a passage rate through a 20 mm sieve of less than 80% by mass, and
- wherein the first combustible waste is combustible waste other than the second combustible waste.
