Basin Electric Power Cooperative has chosen Allen-Sherman-Hoff (A-S-H), a Diamond Power International, Inc. company, to supply a completely dry, bottom-ash handling system – the latest technology for this type of ash removal. The utility’s new 385-megawatt pulverized coal-based plant at Dry Fork Generating Station in Northeast Wyoming will incorporate advanced environmental control technology and is being constructed to meet the growing electricity demand of its members throughout nine states.
The MAC™ System (Magaldi Ash Cooler) is a unique bottom-ash extraction technology that, unlike conventional methods, requires no water to cool or convey the ash. This makes the system an ideal choice for plants, like the Dry Fork Generating Station, located in water-constrained areas. The MAC System is provided in the United States by Allen-Sherman-Hoff under exclusive license from Magaldi Power S.p.A. of Salerno, Italy, the developer of the technology.
“We are pleased to be working with Basin Electric, Sargent & Lundy and Babcock & Wilcox for this important project,” said Stephen Scott, General Manager of A-S-H Engineered Systems. “With 88 systems installed worldwide and an additional seven on order, the MAC System has become the technology of choice for a significant portion of the latest generation of new coal-based power stations and an increasing number of retrofits. Users report water savings, improved reliability, reduced operational and maintenance cost as well as the ability to recycle the dry, low-carbon ash byproduct into higher value products such as Portland cement substitute.”
The new plant will be fueled by Powder River Basin (PRB) coal, which has a tendency to be a heavy slagging fuel. That means that any bottom-ash handling system must be built ruggedly enough that it can withstand impacts from slag accumulations without interrupting operations. This reliability is why the MAC System was the clear choice for this application.
Mr. Scott added, “As part of its efforts to incorporate advanced environmental controls at the plant, Basin Electric is leading the way with its choice of dry, bottom-ash handling technology.”
