Definitions
- the invention relates to a continuous steam generator with a number of burners for fossil fuel whose Um Publishedswand is wholly or partly formed from gas-tight together welded steam generator tubes, wherein the burners are arranged in a combustion chamber, which is followed by a Schugitzi- trough a horizontal gas train a vertical gas train first part of the steam generator tubes is designed as a system of evaporator tubes upstream of a Wasserabscheidesystem Strömungsmediums- side and a second part of the steam generator tubes is formed as a system of the Wasserabscheidesystem flow medium side downstream superheater tubes.
- a fossil-fueled steam generator the energy of a fossil fuel is used to generate superheated steam, which can then be supplied to power a steam turbine, for example, in a power plant.
- steam temperatures and pressures steam generators are usually designed as a water tube boiler, d. h., The supplied water flows in a number of tubes which receive the energy in the form of radiant heat of the burner flames and / or by convection of the resulting during combustion flue gas.
- the steam generator tubes usually form the combustion chamber wall by being welded together in gas-tight fashion.
- the combustion chamber downstream side of the combustion chamber arranged Dampfampfererrohe can be provided in the exhaust duct.
- Fossil fueled steam generators can be categorized according to a variety of criteria: based on the flow direction of the gas flow, steam generators can For example, be divided into vertical and horizontal types. In fossil-fueled steam generators in vertical construction usually a draw-in and two-pass boiler are distinguished.
- the flue gas produced by the combustion in the combustion chamber always flows vertically from bottom to top. All arranged in the flue gas heating surfaces are above the combustion chamber. Tower boilers offer a comparatively simple construction and easy control of the stresses resulting from the thermal expansion of the pipes. Furthermore, all heating surfaces in the flue gas duct are arranged horizontally and therefore completely drainable, which may be desirable in frost-prone environments.
- Steam generators may continue to be designed as a natural circulation, forced circulation or continuous steam generator.
- a continuous steam generator the heating of a number of evaporator tubes leads to complete evaporation of the flow medium in the evaporator tubes in one pass.
- the flow medium - usually water - is supplied to the evaporator tubes downstream superheater tubes after its evaporation and overheated there.
- this description is only valid for partial loads with subcritical pressure of water (P K ⁇ ⁇ 221 bar) - where at no temperature water and steam can occur simultaneously and thus no phase separation is possible - valid in the evaporator.
- P K ⁇ ⁇ 221 bar subcritical pressure of water
- the position of the evaporation end point, d. H. The place where the water content of the flow is completely evaporated, is variable and mode-dependent.
- the evaporation end point is located, for example, in an end region of the evaporator tubes, so that the overheating of the vaporized flow medium already begins in the evaporator tubes.
- a continuous steam generator In contrast to a natural or forced circulation steam generator, a continuous steam generator is not subject to any pressure limitation, so that it can be designed for live steam pressures far above the critical pressure of water.
- such a continuous steam generator is usually operated with a minimum flow of flow medium in the evaporator tubes in order to ensure reliable cooling of the evaporator tubes.
- a minimum flow of flow medium in the evaporator tubes in order to ensure reliable cooling of the evaporator tubes.
- the pure mass flow through the evaporator usually no longer suffices for cooling the evaporator tubes, so that an additional throughput of flow medium is superimposed on the passage of flow medium through the evaporator in circulation.
- the operationally provided minimum flow of flow medium in the evaporator tubes is thus not fully evaporated during startup or during low load operation in the evaporator tubes, so that in such a mode at the end of the evaporator tubes still unvaporized flow medium, in particular a water-steam mixture is present.
- the superheater tubes connected downstream of the evaporator tubes of the continuous-flow steam generator are not designed to flow through unvaporised flow medium until after the flow through the combustion chamber walls, continuous-flow steam generators are usually designed such that Even when starting and in low load operation, a water inlet into the superheater pipes is safely avoided.
- the evaporator tubes are usually connected to the superheater tubes connected downstream via a water separation system.
- the water separator causes a separation of the emerging during the start or in low load operation of the evaporator tubes water-steam mixture in water and in steam.
- the steam is supplied to the water separator downstream superheater tubes, whereas the separated water can be fed back to the evaporator tubes, for example via a circulating pump or discharged through a decompressor.
- the above-mentioned concept causes high temperature differences between evaporator tubes and superheater tubes:
- unevaporated flow medium flows at saturation temperature in the evaporator tubes, while steam at higher temperatures still exists in the superheater tubes.
- the evaporator tubes are filled with cold feed water while the superheater tubes are still at operating temperature level. This can lead to overloading and damage to the materials due to the different thermal expansion.
- the invention is therefore based on the object of specifying a continuous steam generator of the type mentioned above, which involves a comparatively lower repair costs and has a comparatively long service life.
- the invention is based on the consideration that a reduction in the repair effort and an increase in the service life of the continuous steam generator would be possible if Damage could be minimized by different thermal expansion of welded steam generator tubes.
- the differential expansion is the result of high temperature differences between the steam generator tubes. These temperature differences are caused by different cooling of the steam generator tubes and by different temperatures of the flowing in them flow medium and therefore occur in particular at the separation between welded together evaporator and superheater tubes, as these by the intermediate Wasserabscheidesystem especially during cold and hot start a have different flow of fluid at different temperatures.
- the combustion chamber wall of the continuous steam generator is formed from evaporator tubes and a side wall of the horizontal gas flue formed from superheater tubes, wherein the adjoining the combustion chamber superheater tubes are downstream of the Wasserabscheidesystem flow medium side.
- the ceiling of the continuous steam generator is formed from superheater pipes which are connected downstream of the water separation system on the flow medium side. This means that the superheater pipes of the ceiling are connected in parallel to other superheater pipes adjacent to the evaporator pipes.
- Such a circuit is advantageous by the parallel connection of the heating surfaces in terms of the expected pressure loss.
- the advantages achieved by the invention are in particular that the temperature differences between these pipes are consistently minimized by the flow medium side immediate downstream of parallel to the evaporator tubes superheater pipes to the Wasserabscheidesystem. As a result, the different thermal expansion is minimized and damage and overloads prevented, which has a lower repair liability and longer life of the continuous steam generator result.
- FIG. 1 shows a continuous steam generator in Zweizugbauweise in a schematic Dar- position.
- the continuous steam generator 1 according to the figure comprises a combustion chamber 2 designed as a vertical gas train, which is followed by a horizontal gas train 6 in an upper region 4. At the horizontal gas train 6, another vertical gas train 8 connects.
- the combustion chamber wall 12 is formed from steam generator tubes which are welded together in a gas-tight manner and into which a flow medium, usually water, which is heated by the heat generated by the burners, is pumped in by a pump (not shown).
- a flow medium usually water
- the steam generator tubes can be aligned either spirally or vertically. In a spiral arrangement, a comparatively higher construction effort is required, but the resulting heating differences between pipes connected in parallel are comparatively lower than in the case of a combustion chamber 2 with a perpendicular bore.
- the continuous steam generator 1 shown further comprises, to improve the flue gas duct, a nose 14, which merges directly into the bottom 16 of the horizontal gas flue 6 and projects into the combustion chamber 2.
- the steam generator tubes of the combustion chamber 2 are designed as evaporator tubes.
- the flow medium is first evaporated in them and fed via outlet collector 20 to the water separation system 22.
- Wasserabscheidesystem 22 not yet evaporated water is collected and removed. This is necessary, in particular during start-up operation, when a larger amount of flow medium has to be pumped in for safe cooling of the evaporator tubes than can be evaporated in an evaporator tube passage.
- the generated steam is passed into the inlet header 24 of the downstream superheater tubes, which form the ceiling 26 of the continuous steam generator 1 and the walls of the horizontal gas flue 6.
- the transition from the side walls of the vertical gas flue to the side walls of the horizontal flue 6 represents the separation point 18 between evaporator tubes of the combustion chamber wall 12 and superheater tubes in the walls of the horizontal flue 6.
- these superheater tubes are connected directly downstream via the Wasserabscheidesystem 22 via a connecting line 28. As a result, these superheater tubes are only supplied with saturated steam and not with superheated steam of higher temperature, which reduces the temperature.
- the superheater tubes are connected in the walls of the horizontal gas flue 6 parallel to those of the ceiling 26 and are flowed through from top to bottom. In the event of an overflow of the water separation system 22, non-evaporated flow medium can thus be removed in the outlet headers 30 of the superheater tubes and stagnation of the flow can not occur.
- the temperature differences are minimized at the separation point 18 between the evaporator tubes of the combustion chamber wall 12 and the superheater tubes in the walls of the horizontal gas flue 6, whereby damage can be effectively prevented. This results in a comparatively lower repair susceptibility and longer life of the continuous steam generator 1.
