Patent ID: 8025705

Claim:
A method for gasification of fuel in an entrained flow of a gasification reactor, comprising: jointly gasifying a mixture of at least two different fuels with different degrees of coalification from the table shown below wherein the different fuels are fed to different drying and pulverizing systems to obtain the respective grain size distribution and moisture content specified therein; providing a plurality of sluices for conveying the mixture to a dispensing vessel wherein the sluices are operated to enable continuous operation of the dispensing vessel; and transporting the mixture from the dispensing vessel to a gasification reactor Grain size Moisture Fuel distribution content Petrol coke (low Anthracite {close oversize brace} reactivity 50% < 63 μm Stone coal V daf ≦18%) 95Ma % < 200 μm <2 wt. % Pyrolysis coke ≧99% < 250 μm <2 wt. % 98% < 500 μm Stone coal ≧94% < 250 μm <2 wt. % 98% < 500 μm Hard brown coal ≧94% < 250 μm <8 wt. % 98% < 500 μm Soft brown coal ≧55% < 100 μm <12 wt. %. ≧97% < 500 μm
