    Gas cofiring for coal-fired utility boilers. Final report

    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 basic cofiring rate for natural gas was defined as 10--20% of the boiler`s …
