| 摘要 |
A method for improving the efficiency, enhancing the heat output, and reducing the harmful emissions of a solid carbonaceous fuel combustion system by introducing a hydrogen-rich gas into a solid carbonaceous fuel combustion process at one or more predetermined injection points or directly into a flame of the combustion process where the hydrogen-rich gas is controlled to be introduced at a desired flow-rate. The gas is introduced through one or more predetermined injection points which are selected from one or a combination of one or more primary air streams with the solid carbonaceous fuel prior to combustion, one or more secondary air streams with the solid carbonaceous fuel at combustion, one or more tertiary/overfire air streams downstream of the solid carbonaceous fuel combustion, and one or more injection ports near an exit end of a furnace of said combustion process.
