20110120139 | MODIFIED GAS AND STEAM TURBINE PROCESS WITH INTEGRATED COAL GASIFICATION UNDER PRESSURE - A process for the production, treatment and combustion of synthesis gas for the purpose of generating electric power is disclosed. The synthesis gas is produced from a solid, carbon-containing fuel with the aid of an oxygen-containing gas and treated by a slag-separating device and a device separating alkalis. Subsequently, the synthesis gas produced is fed to an expansion turbine where the pressure energy is used for generating power. On account of the treatment and separation of alkalis the expansion turbine is protected from corrosion and mechanical impact. The expanded synthesis gas is then burnt under pressure and the combustion is used in a combined-cycle process using a gas turbine, steam generator and steam turbine for generating power. The process thus has an increased efficiency. Apparatus for use of the process is also described. | 05-26-2011 |

20120298920 | METHOD FOR BIOMASS GASIFICATION IN A FLUIDIZED BED - With a method for the gasification of a biomass in a fluidized bed, wherein the biomass is first pre-dried and passed to the fluidized bed gasifier, subsequently the raw gas from the gasifier impacts a recirculation cyclone and subsequently at least one raw gas cooler, the yield of such a method of procedure is supposed to be improved and the system costs are supposed to be lowered. | 11-29-2012 |
20130168608 | METHOD FOR THE GENERATION OF SYNTHESIS GAS - With a method for the generation of synthesis gas by means of gasification of solid or liquid carbonaceous fuels with an oxidation agent containing oxygen, in a reactor, wherein the synthesis gas is passed out of the reactor overhead, and the mineral ash/slag droplets that occur during the reaction are passed out of the reactor downward, in the direction of gravity, it is supposed to be made possible to use a flue-tube boiler, which is clearly less expensive, for heat removal in place of radiant boilers. This is achieved in that the synthesis gas is passed over a hot-gas filter ( | 07-04-2013 |
20140374661 | METHOD FOR PRODUCING SYNTHESIS GAS BY GASIFYING A BIOMASS IN A FLUIDIZED BED - A method for producing synthesis gas by gasifying a biomass in a fluidized bed is disclosed wherein the biomass is fed to a fluidized bed gasifier.
