20090025294 | Simultaneous gasification of coals of widely differing degrees of coalification in entrained flow gasification - The invention relates to a gasification method which, with a reliable and safe mode of operation, allows the simultaneous gasification of coals of different degrees of coalification, including those of differing coal qualities such as brown coals and stone coals, with the pulverized fuel consisting of the mixture of the different coals being fed from a common dispensing system to the gasification reactor. | 01-29-2009 |
20090077885 | Entrained-flow gasifier with cooling screen and sliding seal - In a reactor for gasification of entrained solid and liquid fuels at temperatures between 1,200 and 1,900° C. and at pressures between ambient pressure and 10 MPa using an oxidizing agent containing free oxygen, the cooling screen is connected to the pressure shell in a gastight manner via a sliding seal in order to allow length changes. Continuous gas purging of the annular gap between pressure shell and cooling screen is unnecessary and gasification gas is prevented from flowing behind. | 03-26-2009 |
20090077886 | Entrained-flow gasifier with cooling screen and bellows compensator - In a reactor for the gasification of solid and liquid fuels in the entrained flow at temperatures between 1200 and 1900° C. and pressures between ambient pressure and 10 MPa with an oxidizing agent containing free oxygen, the cooling screen is connected in a gas-tight manner to the pressure shell via a bellows compensator to accommodate linear deformation. Continuous sweeping by gas of the annular gap between pressure shell and cooling screen is unnecessary and backflow by producer gas is prevented. | 03-26-2009 |
