Definitions
- the invention relates to a method for operating a burner, according to the Preamble of claim 1.
- the nozzle can also be used with a so-called Ignition level can be provided. It is a second Atomizer, which is designed for correspondingly small throughputs and therefore at Partial load ensures a sufficiently fine atomization of the liquid fuel.
- a second Atomizer which is designed for correspondingly small throughputs and therefore at Partial load ensures a sufficiently fine atomization of the liquid fuel.
- This nozzle with their two fuel supply lines and with two radially one above the other Fuel channels, which act on depending on the required fuel mass flow , but requires a relatively large amount of space. They are also components used are naturally filigree, which makes the nozzle more susceptible to failure.
- pp. 142-144 and Fig. 4.50 is an atomizer for liquid fuels known, in which an auxiliary gas upstream of the injection opening is introduced into the liquid flow.
- a gas pipe is arranged which ends upstream of the injection opening and is provided with a plurality of outlet openings for the auxiliary gas.
- the injection of the auxiliary gas in the liquid flow takes place at low speed and with only slightly higher pressure than the liquid flow.
- This in the auxiliary gas emerging from the liquid forms gas bubbles, due to their influence relatively thin scraps of liquid and bands appear in the liquid flow. Because such Liquid flows with a smaller diameter easier to a fine Spray can be dissolved, this will atomize the liquid Improved fuel.
- With the injection of the auxiliary gas into the liquid fuel pipe the total volume flow to be atomized is increased so that sufficient atomization even with partial load using a full jet atomizer of the fuel is available.
- the invention tries to avoid all of these disadvantages. You have the task is based on a simple and suitable method for all operating conditions To create operation of a burner.
- this is achieved in that in a method according to the preamble of claim 1, the auxiliary gas only in the ignition and at Partial load of the burner fed and the supply interrupted at high load ranges becomes.
- the atomizer nozzle which is known per se, can now be used both on ignition and Low load conditions as well as under high load conditions and of course at Full load can be optimally adjusted. In this way the respective range of applications such an atomizer nozzle or one equipped with it Brenners significantly expands your use with one with different combustion air pressures, such as. in a gas turbine, operated combustion chamber is only made possible by this.
- the premixing of the liquid in the burner can Low-emission combustion can be achieved with the auxiliary gas.
- An additional advantage results when using the method in axially mounted Brennkammem, in which the burners at different geodetic heights are arranged.
- the supply of the auxiliary gas can, in particular, otherwise uneven distribution of the liquid fuel that occurs during ignition significantly reduced, thus increasing the functional reliability of the combustion chamber become.
- auxiliary gas from a pressure vessel or Auxiliary compressor is supplied to the burner. According to the specific conditions of use the burner is therefore a suitable source for the auxiliary gas given.
- Compressed air is particularly advantageously supplied as auxiliary gas. This is done at Requires either compressed ambient air or compressed air from the already pressure tank filled before igniting the burner used
- the insert of ambient air as auxiliary gas is particularly cheap because it is constantly is available.
- the invention can also be used with inert gases, e.g. Nitrogen, with ignition gases (e.g. propane) or with fuel gases (e.g. natural gas) will be realized.
- inert gases e.g. Nitrogen
- ignition gases e.g. propane
- fuel gases e.g. natural gas
- a plurality of burners 1 are arranged in the gas turbine system, not shown, which are operated with a liquid fuel 2, more precisely with fuel oil. Naturally other suitable fuels can also be used.
- Each burner 1 consists of an outer air tube 3 and a coaxial inside the air tube 3 arranged atomizer nozzle 4, both in one Combustion chamber 5 of the gas turbine system open out.
- the atomizer nozzle 4 has a Liquid fuel tube 6 with an interior 7, a fuel feed line 8 and one circular injection opening 9.
- a gas pipe 11 connected to a feed line 10 is arranged, which several Has outlet openings 12 in the interior 7.
- the interior 7 is in the direction the injection opening 9 tapers, i.e. with a guide piece 13 for that Fuel oil 2 formed
- the feed line 10 has a control valve 14 with which the Gas pipe 11 can be opened or blocked.
- each burner 1 When operating the gas turbine system, each burner 1 is switched over the corresponding one Fuel supply line 8 supplied with fuel oil 2.
- the fuel oil 2 comes first in the interior 7 of the liquid fuel tube 6, where it through the Fuel pressure is further promoted in the direction of the injection opening 9.
- Gas turbine system is arranged via the feed line 10 and in the gas pipe 11 Outlet openings 12 serving as auxiliary gas 15, compressed air into the Interior 7 located fuel oil 2 initiated.
- This injection takes place with less Speed and with an insignificant compared to the fuel oil 2 higher pressure of about 0.1 to 3.0 bar.
- the air serving as auxiliary gas 15 becomes the compressor section, not shown removed from the gas turbine system pre-compressed and, if necessary, also via one brought auxiliary compressor, not shown, to the required pressure.
- the air 15 can also be supplied from a pressure vessel.
- the fuel throughput of the Brenner 1 constantly.
- the fuel pressure increases in line with the fuel throughput in the burner 1 and in the atomizing nozzle 4. If the atomization is sufficient required fuel pressure is reached, the air supply is through Closing the control valve 14 interrupted. With the control valve closed 14, i.e. at high fuel pressure, the fuel oil 2 is by means of the circular Injection opening 9 distributed to a fine, suitable for combustion spray.
- auxiliary gases such as inert gases (nitrogen) or ignition gases (propane) or fuel gases (Natural gas) can be used.
