Description

Thanks to the MAR® system, they can be turned from a costly waste to be disposed of into a valuable coal combustion product (CCP) used in cement or concrete production. The MAR® system can be implemented in new projects or as a retrofit, replacing conventional wet systems with a MAC® (Magaldi Ash Cooler) + MAR® system package. Dry bottom ash, extracted and cooled by the MAC® system, and ash from ECO hoppers are pneumatically transported and stored in small reception bins installed at the coal bunkers level. The ash is then extracted by tubular vibro-feeders and dosed to the coal mill feeding hoppers before being milled with coal by pulverizers and injected into the boiler through coal burners. Fly ash and bottom ash have different characteristics (mainly in terms of particle size and shape). For this reason, two separate disposal systems are typically required (with different silos and conveying system technologies). The conversion of all bottom and ECO ash into fly ash allows the elimination of all costs associated with ash transport from the local silo to the final disposal area. Power plant operators must only take care of fly ash disposal.
