Definitions
- the invention relates to a method for lignite processing for gas-steam combination processes of a heat generation system.
- FIG. 1 Also known is a method for operating a gas-steam combination process (DE-OS 3907217).
- the method is divided into two technological concepts, the concept shown in FIG. 1 including the operation of the ballast gas turbine with natural gas. This solution is trivial and has been in commercial use for years.
- the second concept, shown in FIG. 2 includes pressure fluidized bed coal gasification of a coal part stream. Since the coal partial flow gasification is preceded by a steam fluidized bed drying and this drying is not in the energetic connection with the Combi block is standing, this must be operated with electro-intensive vapor recompression and external vapor deduster, so that this block concept has a low efficiency of 42 - 44%.
- the technical outlay on the plant is very large, because in addition to the typical combi block equipment, a gas turbine system, intercooling of air, connecting piping and ducts, a pressure-charged fluidized bed gasification reactor with associated hot gas deduster and an electro-energy-consuming drying technology (without an energetic combination with the combi block) are required.
- the invention has for its object to achieve a significant reduction in CO 2 emissions per unit of power by reducing the use of fossil fuels, the drying facilities for raw lignite being connected to the heat generation system in such a way that a complete energetic utilization of the vapor is realized.
- the drying container is operated in conjunction with a pressure fluidized bed furnace, a gas turbine, a steam turbine, an air-heated steam reheater and a waste heat boiler, the drying energy of the drying container is obtained via saturated steam from the waste heat boiler of the combination process, the energy content of the vapor under medium pressure and dedusted is used to evaporate a feedwater partial stream and the gas turbine is operated with exhaust gases from the pressure fluidized-bed furnace, intermediate vapor heating with combustion air cooling is carried out by means of compressed combustion air, and the vapor condensate formed by energetic combination after its treatment for water supply of the circulatory process is used.
- the invention will be explained in more detail below using an exemplary embodiment.
- Fig. 1 the raw lignite dryer with a combination block and a pressure fluidized bed combustion
- the raw lignite 9 passes through a mill into the vapor-condensing raw fine coal preheater 8, which is followed by the dryer 1 with heating surface package 2.
- the dry coal and an additive are passed through the dry coal additive feed system 3 into the steam boiler 4 with pressure fluidized bed combustion.
- the steam boiler 4 is connected to the steam turbine 5, the cold rail 15 of the steam reheat is coupled to the hot rail 16 via an air-heated steam reheater 13.
- the steam boiler 4 is also connected to the exhaust gas turbine stages 12 of a gas turbine system, which is coupled to a waste heat boiler 17.
- the waste heat boiler 17 has the heating surface 6 for saturated steam generation, which is connected to the heating surface 2 in the dryer 1.
- the vapors formed in the dryer 1 and in the preheater 9 are passed into a vapor-condensing saturated steam generator 7, which is connected to an ash-cooling saturated steam superheater 10.
- the saturated steam superheater 10 is coupled on the one hand via the steam feed line 14 to the cold rail 15 of the steam turbine 5 and on the other hand to the steam boiler 4 and the ash recycling 21.
- the air-heated steam reheater 13 is connected to the steam boiler 4 and the air compressor stages 11 of the gas turbine system.
- the vapor condensate obtained in the saturated steam generator 7 and in the preheater 8 is cooled in the vapor condensate cooler 19 and then passed into the vapor condensate preparation 20.
- a partial stream 18 of the cooled vapor condensate is fed to the ash recycling 21.
- the proposal according to the invention has the advantage that the gas-steam technology with pressure fluidized bed combustion can also be operated with highly humidified lignite and a process efficiency of 47% - 48% at nominal and part load is achieved.
