  • APPARATUS AND METHODS FOR LARGE PARTICLE ASH SEPARATION FROM FLUE GAS USING SCREENS HAVING SEMI-ELLIPTICAL CYLINDER SURFACES
    Publication number: 20150075378
    Abstract: Apparatus for separating ash particles from a flue gas. The apparatus includes a screen that has a plurality of semi-elliptical cylinder surfaces. The semi-elliptical cylinder surfaces having holes through which said flue gas flows and through which the ash particles will not pass. The screen has a single layer for performing the separation in a manner such that the ash particles fall away from the screen and collect outside of the screen. A method of reducing velocity of a flue gas passing through screening apparatus for separating flue gas from ash particles. The method includes replacing a first screen of the screening apparatus with a second screen that has a plurality of semi-elliptical cylinder surfaces.
