Technical And Economic Assessment Of Coal Mine Methane In Coal-Fired Utility And Industrial Boilers In Northern Appalachia And Alabama.
Coal mine methane (CMM) emissions can occur in the form of gob gas, a by-product for which power industries are attempting to identify potential uses. One possible use of gob gas is as supplemental fuel for industrial and utility boilers delivered in dedicated pipelines. Since gob gas may be cofired with the primary fuel in a variety of existing combustion units, it can partially replace common fuels. Cofiring gob gas can provide greater value to the buyer than that of the replaced primary fuel. This report refers to an "enhanced" gob gas value, which is the sum of the avoided fuel plus associated environmental and operational benefits.
This report provides the following:
The purpose of this report is to acquaint potential coal mine operators and energy project developers with the fundamentals of project selection for cofiring gob gas with coal in utility and industrial boilers.
- A review of the benefits of cofiring;
- A methodology for selecting markets and cofiring projects that have the greatest likelihood for technical and economic feasibility;
- An explanation of the key variables that determine whether or not a project might be viable;
- Two typical cases that appear to exhibit economic viability;
- A summary of several other potential cofiring scenarios for Northern Appalachia and Alabama locations that appear to be feasible and economically attractive.
