  • How to compare Natural Gas Boiler and Coal Boilers?

    Apr 05, 2017 · Gas burners can be turned up and down very easily and quickly compared to coal, especially, stoker type coal boilers. Gas burners can also be used for pilot burners to start the flame, and for flame stabilization at low load factors. Boiler Types and Gas Co-firing. There are two primary types of coal boilers, stoker and pulverized (PC).Learn More

  • Gas cofiring for coal-fired utility boilers. Final report

    Nov 01, 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 basic cofiring rate for natural gas was defined as 10--20% of the boiler`s …Learn More
