Definitions
- the invention relates to a method for operating a combined gas turbine / steam turbine process in which the supercharged advance gas turbine process by means of compressed air and a fuel fluid and the
- Fluidized bed firing with the oxygen-containing exhaust gases from the primary gas turbine process takes place and electrical energy can be generated with both turbine processes.
- the gas generated in the pressure gasification is at a very low pressure level, e.g. B. 1.35 bar relaxed and a circulating atmospheric fluidized bed
- Fluidization air takes place in two stages, the first in the compressor of a turbocharger and the second in one driven by a gas turbine
- the air is intercooled between the two stages in order to keep the compression work small overall.
- the compressed air is in one before the entry into the combustion chamber of the pressure fluidized bed
- Preheated air preheater which is acted upon by the flue gas from the pressure fluidized bed combustion, which is partially expanded in the gas turbine.
- heat is removed from the flue gas, which is still under higher pressure, to the compressed air.
- the air preheater is followed by a feed water preheater in which heat is still transferred to the feed water. The energy then remaining in the flue gas is sufficient to operate the
- Pressure fluidized bed is a limit for increasing efficiency and specific work.
- the invention provides that the exhaust gases of the
- Pressure fluidized bed can be operated, and that the exhaust gases from the pressure fluidized bed combustion after dedusting are expanded in a second gas turbine process and thereafter a heat exchange with the compressed air of the
- the compression energy for the first stage being applied by the second gas turbine process and the compression energy for the second stage being applied by the preliminary gas turbine process.
- Fuel flexibility, natural gas and oil can be used as fuel fluids in plants to be built at short notice
- the primary gas turbine can also use coal gas, hydrogen or from the gasification of coal
- Methanol / ethanol are fired.
- the method according to the invention leads to systems with a high power density, which are distinguished in particular by good part-load behavior.
- Fluidized bed in particular highly expanded fluidized bed with trap separation.
- VoraItturbinen process partially compressed air is supplied to the first compression stage. Further subclaims relate to advantageous ones
- FIG. 1 a fluidized bed combustion with supercharged primary gas turbine, exhaust gas turbine and
- FIG. 2 a circuit comparable to FIG. 1 where, however, the feed gas turbine with one in one
- Low-pressure turbine 2 builds a gas turbine set 3, compressed in a first stage, via a valve 4, a partial flow of this compressed air is fed to the combustion chamber 5 of a pressure fluidized bed combustion system 6, shown schematically. Another partial flow is located in a steam turbine system 7 connected downstream of the pressure fluidized bed furnace 6 in the feed water circuit
- Recooler 8 recooled and then in one
- High pressure compressor 9 further compressed.
- the compressed air is preheated in a preheater 10 and into a combustion chamber 12 fired with natural gas 11
- VoraItgasurbine 13 initiated.
- the combustion gas is expanded in the gas turbine to a pressure suitable for the operation of the pressure fluidized bed combustion and corresponding to the pressure of the partial air flow supplied via valve 4 and then to the combustion chamber 5
- Compressed fluidized bed combustion 6 supplied.
- the flue gas from the pressure fluidized bed combustion 6 is filtered in a hot gas filter 14 and the
- Low pressure turbine 2 supplied.
- the flue gas cools down according to the pressure ratio during expansion.
- downstream feed water preheater 15 used.
- absolute mass flows and outputs are given.
- the process which has not yet been optimized, has an efficiency of 47.5%, yields a specific useful output of 3.8 and a CO 2 emission value of 0.189 kg / MJ with a natural gas share of 24.3% of the total
- valve 4 If the valve 4 is closed, i.e. H. only the combustion gas from the natural gas-fired gas turbine is used as an oxygen carrier
- FIG. 1 shows that the gas turbine set 3 and the supercharged advance gas turbine 13 can be coupled to a generator 17 via couplings 16a and 16b, respectively. It is advantageous to clutch 16b when starting the gas turbine set 3 or at extreme
- the system according to FIG. 1 offers the cheapest way for regulation, partial loads by reducing the
- a bypass line 18 assigned to the turbine 2 is first opened and then the gas turbine 13 is started up.
- the gas turbine exhaust gas is hot enough to heat the fluidized bed onto the
- the combustion chamber 12 becomes coal gas as a fuel gas
- the coke formed in the partial gasification 19 is fed via line 21 together with the separated dust 22 to the pressure fluidized bed combustion 6 together with the coal 5a.
- a partial flow of the compressed air is fed to the pressure fluidized bed partial gasification 19 via a branch line 23.
- the coal 19a fed to the partial pressure gasification 19 can be pre-dried in a steam fluidized bed dryer 24 known per se. Furthermore, in FIG. 2
- Fluidized beds with arranged in the interior of the reactor
