ABSTRACT:
In a process for incinerating liquid, gaseous or pasty waste, the steps of producing a high frequency vibratory flow of a fluid in a pulverzing chamber, introducing the liquid, gaseous or pasty waste into the chamber to be pulverized in said high frequency vibratory fluid flow, providing combustion air to be drawn into said high frequency vibratory flow to be mixed with said pulverized waste and igniting the mixture of pulverized waste and combustion air. In addition the present arrangement provides a chamber in which waste material is pulverized. The chamber is equipped with first aperture means and second aperture means. Within the chamber and disposed to face said first aperture is a cavity resonator so that when high pressure fluid passes through said first aperture there results a high frequency vibratory flow of said fluid. Waste material is passed into the chamber through said second aperture simultaneously with combustion air being passed in proximity to the entrance of the chamber lying away from said first aperture. Both the waste material and the combustion air are drawn into the vibratory movement of the fluid and this results in pulverizing the waste material while mixing the pulverized waste with combustion air to render the mixture readily available for incineration.
