| 摘要 |
The present invention concerns a method for binding of the sulfur compounds formed in a pulverized-coal boiler by means of a pulverulent reagent, such as limestone. The method is characterized in that pre-crushed fossil solid fuel and pre-crushed reagent are ground by means of a counter-jet mill which employs compressed air as the operating gas into ultrafine particles and passed directly into the boiler by means of an adjustable after-pressure of the counter-jet mill, the gas portion in the fuel/gas mixture being used as the primary air for the combustion process. |
