| 摘要 |
The present invention or dual fuel slagging gasifier provides the equipment, devices, process and methods for increasing the efficiency, commercialization potential and economy of coal/coke gasification. Entrained, fixed bed and water gasification aspects are combined to generate chemically clean high temperature gases from volatile carbonaceous fuels. A charge body of material including particulate solid low volatile carbonaceous material, quartzite, and a flux can be introduced into an upper portion of a slagging gasifier. Further, a finely divided carbonaceous material can be entrained, gasified at a high temperature and injected into a lower portion of the slagging gasifier. This high temperature heat can then be utilized to convert a stack injected steam and the low volatile carbonaceous fuels to additional fuel gas which enhances calorific value and flow rate of the entrained gas to increase energy conversion efficiency of the dual fuel slagging gasifier above that for all known commercial gasifiers.
