Coal gasification - Wikipedia

A process for keeping coke oven chambers hot during the stoppage of a waste heat boiler. The coke oven chambers are kept hot after emptying using externally heated burners, in which a flue gas low in pollutants is obtained from the burners. The waste heat boilers which, during normal operation, cool the flue gases can be shut off and overhauled, and a flue gas low in pollutants which can be

waste gas streams of approximately 2000 ppm.(Cooper, 2002). d. Other Considerations: The amount of chlorine in the flue gas affects the amount of water evaporated by the system due to the formation of salts. Chlorine content improves the SO 2 removal but also results in salt deposition on the absorber and downstream equipment (Schnelle, 2002).

Jun 19, 2014 · Natural gas emits 50 to 60 percent less carbon dioxide (CO2) when combusted in a new, efficient natural gas power plant compared with emissions from a typical new coal plant . Considering only tailpipe emissions, natural gas also emits 15 to 20 percent less heat-trapping gases than gasoline when burned in today's typical vehicle [ 2 ].
