Use of multiclones with enlarged cyclone elements for collecting coalescing ash

In connection with the development of effective and reliable multicyclones, the possibility emerged for increasing multicyclone use as the primary boiler ash collector. The testing of a multicyclone with enlarged cyclone elements installed in a boiler is described. Reliable multicyclones with 512 mm welded elements made of standard pipe are recommended to replace obsolete gas purification equipment in thermal power plants burning low-grade coal and for which it would be difficult to install more effective ash collectors.
