炭素分は熱分解されて排気口から外部へ出される。The sludge sprayed to the primary combustion chamber is a waste liquid in which solids are crushed and dispersed, and is directly supplied to the spray nozzle for spraying. Therefore, the bubbling step is not necessary. Also,
The sludge waste liquid which has been made into a waste liquid state by crushing the solid content against the flame of the main burner is sprayed downward from the front slightly above the main burner by a small angle, so the spray waste liquid and the main burner However, the solid content of the sprayed waste liquid is instantly vaporized and the combustible solid content particles are almost completely removed. To be incinerated. Even if the solid content in the waste liquid containing a large amount of solid content is sprayed and drops into the bed, it is burned on the hearth where the air is supplied downward. Furthermore, when black smoke is generated due to incomplete combustion in the primary combustion chamber, the black smoke is heated by the secondary burner in the secondary combustion chamber, so the odor and carbon content are thermally decomposed and the exhaust port Is sent to the outside from.
