Abstract
Systems, methods and processes teach by specific examples how the cost of sequestering carbon dioxide (CO2) can be totally offset and turned into profits during coal powered electricity generation from revenue and co-benefits. The process is provided whereby fly ash-carbon mixtures, or de-volatilized coal char, or anthracite coal culm is co-fired in an air-cooled, slagging combustor with limestone or similar slag fluxing materials converts the ash into cementitious slag with properties similar to ground granulated blast furnace slag.

A method by which a cost of sequestering carbon dioxide (CO2) is totally offset and turned into profits during coal powered electricity generation from revenue and co-benefits by using an air-cooled, slagging combustor that is fired fly ash-carbon mixtures, or de-volatilized coal char, or anthracite coal culm and is co-fired in an air-cooled, slagging combustor with limestone or slag fluxing materials to convert ash into cementitious slag with properties of ground granulated blast furnace slag while achieving combustion efficiencies in about a 90% range.
