20120125733 | DEVICE FOR SCATTERING BULK MATERIAL - The invention relates to an apparatus for scattering poured goods, comprising a distributor chute ( | 05-24-2012 |
20120055158 | METHOD FOR OPERATING A STEAM TURBINE POWER PLANT AND DEVICE FOR PRODUCING STEAM FROM LIGNITE - The invention relates to a method for operating a steam turbine power plant comprising at least one steam generator that is fueled by lignite, wherein the lignite is indirectly dried in a fluidized bed dryer that is heated at least partially with steam from the water-steam circuit of the steam generator. Said method is characterized in that the flue gas from the steam generator undergoes gas scrubbing to remove CO2 and that the energy required for the gas scrubbing is at least partially extracted from the drying process in the fluidized bed. The invention additionally relates to a device for creating steam from lignite comprising a drying system for the lignite and a device to scrub CO2 from the flue gas, wherein the drying process and the CO2 gas scrubbing are thermally coupled to each other. | 03-08-2012 |
20110283926 | METHOD FOR GENERATING PROCESS STEAM - The invention relates to a method for generating process steam by burning dried lignite in a steam generator, comprising the drying of moist lignite in a fluidized bed dryer ( | 11-24-2011 |
20110283606 | METHOD FOR PROCESSING BROWN COAL - The invention relates to a process for processing brown coal for combustion and/or gasification for the purpose of power generation, wherein the brown coal moist from the pit is firstly subjected to preliminary crushing and is subsequently comminuted. The milled coal is then fed to drying in a fluidized-bed dryer. The process is characterized in that the milling apparatus is followed by a control sieving facility, with the sieve opening being selected so that essentially 100% of the brown coal passes the sieve. | 11-24-2011 |
20110283555 | INDIRECTLY HEATED FLUIDIZED BED DRYER - The invention relates to an indirectly heated fluidized bed dryer ( | 11-24-2011 |
20110214770 | INSULATING CARTRIDGE - The invention relates to an insulating cartridge for use as part of a pipe jacket insulation, comprising a substantially closed sheet metal casing ( | 09-08-2011 |
20100212320 | METHOD FOR OPERATING A STEAM TURBINE POWER PLANT AND ALSO DEVICE FOR GENERATING STEAM - The invention refers to a method for operating a steam turbine power plant, and also a device for generating steam for the purpose of power generation. | 08-26-2010 |
20080289498 | PROCESS FOR THE PRODUCTION OF CARBONACEOUS ADSORPTION AGENTS DOPED WITH ELEMENTARY SULFUR AND A PROCESS FOR WASTE GAS CLEANING USING SUCH ADSORPTION AGENTS - The invention concerns a process for the production of carbonaceous adsorption agents doped with elementary sulfur, in which sulfur is mixed with the adsorption agent, the mixture is heated to a temperature of between 120° C. and 150° C. and the temperature is maintained over a period of about an hour. The process is distinguished in that heating of the mixture is effected under a controlled oxygen-bearing atmosphere. The invention further concerns a process for waste gas cleaning using carbonaceous absorption agents doped with elementary sulfur. Preferably brown coal coke is used as the adsorption agent. | 11-27-2008 |
20080274874 | SORBENT FOR THE DRY CLEANING OF WASTE GASES CHARGED WITH MERCURY AND PROCESS FOR THE PRODUCTION THEREOF - Sorbent for the dry cleaning of waste gases charged with mercury and process for the production thereof. The sorbent includes as an adsorptively acting constituent for example activated carbons or activated cokes which are mixed with sulfur in powder form at ambient temperature, under the action of atmospheric oxygen. The sorbent is distinguished by a given ratio in respect of the median values of the grain size of the adsorptively operative constituent to the sulfur. | 11-06-2008 |
