Abstract: A honeycomb body of ceramic material for use in installations for cleaning and/or regenerating gases, comprising a prismatic body, which is penetrated by many rectilinear gas-flow channels parallel to one another, which discharge into both face ends of the honeycomb body, wherein the honeycomb body (1) has at least one tubular recess (5, 5?), which is oriented transversely to the direction of the flow channels (4).

Abstract: A process for producing a honeycomb body from a noncatalytically active ceramic material for thermal regenerators, comprising the steps of (a) providing a block-shaped monolithic honeycomb body created by extrusion that includes in its interior longitudinal channels; (b) applying a thermal pretreatment to the honeycomb body; (c) after step (b), coating or masking the outer walls of the honeycomb body with a glaze-repellent coating, coating all the longitudinal channels of the honeycomb body with a glaze, and then drying the honeycomb body; and (d) after step (c), performing a firing operation at a temperature typical for the glazed material.

Abstract: Process for purifying and/or regenerating gases, in which the gas to be treated is fed to at least one layer of adjacently arranged prismatic honeycomb bodies (1) made of a ceramic material, which honeycomb bodies are provided with a plurality of channels (1?) which are parallel to one another and terminate in the end faces of the honeycomb bodies and through which the gas to be treated flows. The honeycomb bodies (1) are arranged in the layer at a predetermined lateral distance therebetween, which is fixed by two spacers (2) applied at two adjoining honeycomb body side walls (1?).

Abstract: An arrangement for separating coarse ash particles from a flue gas stream is provided, and comprises at least one separation module that is in the form of a block and has a plurality of through channels disposed next to one another in the manner of a screen. The through channels form passages for the passage of flue gas, and each through channel has a cross-sectional area that is less than a cross-section of the coarse ash particles that are to be separated or removed. A side of the separation module that is adapted to receive a flow of the flue gas is made of a ceramic material or of a sintered material having a high mechanical resistance to wear. A holding device is provided for holding the separation module.
