1/11/1992 · Cofiring is the simultaneous firing of natural and pulverized coal in a boiler`s primary combustion zone. Cofiring is a low-capital cost, low-risk technology for trimming stack emissions, and in some cases improving plant operational flexibility, and pushing back generating limitations. From earlier work by the Gas Research Institute (GRI), the
