Because the sub-bituminous coal contained in the Powder River
Basin (Wyoming, USA) is a low sulfur "compliance" coal, its use
by utilities continues to increase.
Although Powder River Basin (PRB) coal meets USA emission and
clean air standards, there are many other considerations. PRB
coal is friable with low surface moisture, thus it is very dusty
and a risk for accidental fire or explosion. A quality design
will achieve a safe and efficient fuel handling system.
Any facility using PRB coal must implement automatic wash-down,
elimination of flat areas for dust to collect, handling systems
that minimize dust generation, as well as fire detection and suppression
systems. Roberts & Schaefer Company's 30 years of project history
in the design and construction of mining facilities in the Powder
River Basin brings quality designs to utilities presently burning
or planning to burn PRB coal.
Two examples identifying our significant expertise are presented
below.
