Abstract

The invention provides a process and apparatus for gasification to treat solid particleed carbonacius fuels with high moisture content. Fuel is fed into Vessel for pressurized drying. Machine or more Without having to add water to the fuel Reduce the moisture content of the fuel in the drying vessel (possibly more than one) to the optimum level for gasification by moving the hot gas. Pass Vessel for drying that machine or each machine. In order to provide the fuel particles It has been cascaded together in the gas flow. In this way it makes the gas Cools and humid To separate the cooled and moistened gas from the fuel. Transfer the fuel with a reduced moisture content then from Vessel to the Dry that machine or each one into a Vessel for gasification, converts that fuel into a Vessel gas for gasification to produce the hot gas that is the product and feed at least part of the gas. The hot product enters Wessel to Drying that machine or each machine The invention is also involved in a process. That are combined into one process To provide power production, especially electric power From solid carbonacius partitions

In the pre-drier to facilitate the introduction of these fuel particles into the Vessel. To dry this machine or each machine 1 0. Process in accordance with Clause 8 or 9, any of the above. Where to supply heat to Pre-drier using the steam produced at the end of the stream from the wessel for drying. (Possibly more than one) 1 1. Machine for gasification of solid particleed carbonacius fuels. With high moisture content Which will include Vessel for gasification for making such fuels gas To produce gas Hot that the product came up Vessel for pressure drying, one or more for the Reduce the moisture content of such fuels down to a level suitable for gasification and For cooling and humidification of hot gas that is at least the product One by passing through the vessel to dry this machine or each. In such a way that the fuel particles are coherent in this gas stream The method for introducing the fuel to the Vessel for drying this machine or each The machine without adding water to this fuel. Path for the transfer of hot gas that is such a product, at least in part from Vessel for the gasification of the said gas to the Vessel for drying this machine or each at a temperature in such a way that Significant pyrolysis of fuel particles in Vessel for drying (perhaps more than one machine) will be avoided. This method for separating cooled and deformed gas is avoided. Leave Such fuels and the means for transferring them with reduced moisture content from This or each of this drying vessel to a vessel for gasification 1 2.
