Abstract
This method relates to a non-draining type human waste disposal by pulse combustion drying. In the method, a pulsating combustion gas is discharged downward into a vertically cylindrical dryer from a pulse combustor disposed at the top of the dryer, and making contact the pulsating combustion gas with residue-removed human waste, digester chamber sludges or their mixtures charged therein, turning the charged matters to dried powder and steam under the dryer conditions of 120.degree.-150.degree. C., withdrawing the dried powder from the bottom of the dryer and the combustion gas containing steam from a lower side of the dryer, dust-removing the combustion gas containing steam maintained at 120.degree.-150.degree. C., deodorizing the dust-removed combustion gas, and exhausting the deodorized gas into the air. As an alternative method, the dried powder and the combustion gas containing steam are withdrawn from the bottom of the dryer, the withdrawn material maintained at 120.degree.-150.degree. C. is charged to a incinerator, odorous components and the dried powder entrained in the combustion gas containing steam are incinerated under supply of a fuel and combustion air, dust-removing the incinerated matters, and exhausting the dust-removed gas into the air.
