Pulse jet cleaning of rigid ceramic barrier filters separating hard and brown coal fly ashes at high temperatures
Abstract
The regeneration of rigid surface filters was investigated under the influence of high temperatures for various dusts. In this connection, the conditions prevailing in the cleaning system were varied specifically. It became apparent that the cohesive and adhesive characteristics of the dusts at high temperatures, as well as material and structure of the filter elements, are of considerable importance with regard to the dedusting results. These conditions and the filtration velocity are usually determined by the process. The parameters at the cleaning system, on the other hand, can be adjusted in such a way as to improve the operating behavior of the filter. Thus, a prolongation of the valve opening time, an increase of the pressures in the jet gas reservoir and the filtration of thicker dust layers improve the regeneration of the filter element.
