20090064581 | PLASMA-ASSISTED WASTE GASIFICATION SYSTEM - A plasma-assisted waste gasification system and process for converting waste stream reaction residues into a clean synthesis gas (syngas) is disclosed. The feedstock is fed into a reactor roughly one-third from the bottom through the use of a feed mechanism. The reactor has three zones; a bottom zone where melting occurs, a middle zone where gasification takes place, and a top zone with integrated plasma torches to control the temperature and polish the syngas. The residence times in the three zones are selected to optimize the syngas composition and melted products. The syngas leaves the reactor and is partially quenched with relatively cooler synthesis gas. The partially quenched syngas is further cooled to recover heat for steam generation and/or preheating the waste stream to the reactor. The cold syngas is then processed to remove pollutants. The clean synthesis gas is combusted in power generation equipment to generate electricity, or converted to other fuels by chemical processes. | 03-12-2009 |

20110154736 | SLAG DISCHARGE FROM REACTOR FOR SYNTHESIS GAS PRODUCTION - With a method for discharging slag from a water bath of a reactor for synthesis gas production, whereby the slag is brought to a lower pressure level by means of a transfer container, a solution is supposed to be created, with which the components connected with transferring the slag out are subject to a low temperature, whereby immediate slag transfer without water exchange is supposed to be made possible, with a minimal required cooling power. This is accomplished in that a cooling water stream is passed to the slag stream in the outlet region of the slag from the water bath of the gas generator or the pressurized container that surrounds it, in a region having a greater cross-section than the cross-section of the entry connector of another system part, such as, for example, the transfer container, in such a manner that temperature stratification in the outlet region is made possible. | 06-30-2011 |
