Definitions
- the invention relates to a waste heat boiler for cooling hot Syngas with the features of the preamble of the claim 1.
- Hot synthesis gases such as B. in oil or Residue gasification plants are generated in one Gasification reactor downstream synthesis gas waste heat boiler cooled.
- the heat energy contained in the synthesis gas is recovered, producing high-pressure saturated steam. to This saturated steam is usually used for further useful purposes overheat.
- Synthesis gas waste heat boiler for high-pressure saturated steam generation consist, for example, of spiral-shaped coils or a bundle of straight or U-shaped tubes, which form the heat exchange surface.
- the hot synthesis gas flows through these coils or tube bundles and gives his Heat to the coil or tube bundle inside a pressure jacket surrounding and under boiling pressure Water.
- the saturated steam is in a separate, the waste heat boiler downstream superheater overheated. It is also in Synthesis gas waste heat boiler integrated steam superheater known which consist of spirally shaped coils that the Waste heat boiler coils are connected downstream and at which the synthesis gas in the same way as in the waste heat boiler Flow through the pipe coil.
- the superheater coils show in usually a smaller pipe diameter than the waste heat boiler coils on.
- the saturated steam is around Superheater pipe coil led and overheated. This type has the following serious disadvantages: It is specifically expensive and complex; it is only with considerable Inspect and repair effort.
- synthesis gas waste heat boilers are integrated Pipe coil steam superheater known (Chem.-Ing.-Techn. 56 (1984 No. 5, pp. 356-360), in which the synthesis gas around the Pipe coils and the saturated steam to be overheated through the Pipe coils are guided.
- Steam superheater applies that it is specifically expensive and complex and can only be inspected and repaired with considerable effort is.
- at least during gasification they become more fluid
- the flow channels between the coil are used blocked by deposits from the synthesis gas. This Deposits cannot be removed and do so Superheater ineffective after a certain time.
- the invention is based, so the superheater in the task to integrate the waste heat boiler that a simple and Inexpensive design is created in which the superheater is relatively easy to inspect, clean and repair.
- the Drawing shows schematically the longitudinal section through the top Part of a waste heat boiler for cooling synthesis gas.
- the waste heat boiler for cooling synthesis gas is a Vertical type heat exchanger. It consists of a pressure jacket 1, a water space 2 and one arranged above it Encloses steam room 3.
- the water room 2 is up to one Liquid level 4 with high boiling pressure Filled with water.
- Pressure jacket 1 attached a feed pipe.
- heat exchanger tubes 5 are arranged are flowed through by the synthesis gas to be cooled.
- the Heat exchanger tubes 5 are bent as a spiral Pipe coils formed, which can be single or multi-course. In the heat exchange with the hot synthesis gas, this evaporates Heat exchanger tubes 5 surrounding water partially and occurs as Saturated steam at the liquid level 4 into the vapor space 3. Above the liquid level 4 is in the Steam room 3 a droplet separator 6 for drying the Saturated steam.
- the heat exchanger tubes 5 serving as evaporators is a Downstream superheater, which cools the synthesis gas further and overheated the dried saturated steam.
- the superheater is at least partially arranged within the pressure jacket 1 and thus integrated into the waste heat boiler.
- the superheater contains a vertically aligned bundle of straight, in several rows of tubes 7 arranged side by side, which in a lower tube sheet 8 and an upper tube sheet 9 tight are used.
- the lower tube sheet 8 represents the upper part a hood-shaped gas inlet chamber 10, in which the Open the heat exchanger tubes 5.
- the bundle of tubes 7 of the superheater is of a guide jacket 11 enclosed, which extends to close to the lower tube sheet 8. A between the lower edge of the guide jacket 11 and a passage is formed in the lower tube sheet 8.
- the superheater protrudes from the pressure jacket 1. At the exit point of the Superheater, the guide jacket 11 is tight with the pressure jacket 1 connected. Outside of the pressure jacket 1 is on the guide jacket 11 an outlet connection 12 is connected.
- the gas outlet chamber 13 and the guide jacket 11 are each with an annular flange 14, 15 Mistake. Between these two ring flanges 14, 15 is the clamped upper tube sheet 9.
- baffles 16 which as baffles serve for the medium flowing around the tubes 7.
- the superheater is arranged within the pressure jacket 1 that the gas inlet chamber 10 with the lower tube sheet 8 itself in the water space 2 below the liquid level 4 located.
- the gas inlet chamber 10 is thus from the Water side well cooled, which prevents material overheating become.
- a collar 18 is with the outer edge of the lower tube sheet 8 tightly connected. This collar 18 surrounds the lower part of the Guide jacket 11 to form an annular space 19. The upper edge of the collar 18 extends upward above the liquid level 4 out into the steam room 3. Between the collar 18 and the Pressure jacket 1, the droplet separator 6 extends across the steam room 3.
- the waste heat boiler described works in the following way.
- the hot synthesis gas to be cooled for example from one Gasification reactor becomes the coils of the heat exchanger tubes 5 supplied, flows through these heat exchanger tubes 5 and enters the gas inlet chamber 10 a.
- the gas entry chamber 10 distributes the synthesis gas to the pipes 7 of the superheater. To flowing through the pipes 7 of the superheater Syngas in the gas outlet chamber 10, from where it is dissipated.
- the pressure jacket 1 of the waste heat boiler is so much under high Pressurized water that feeds the liquid level 4 is maintained at a predetermined level. That in that Water space 2 existing, the heat exchanger tubes 5 surrounding Water evaporates in the heat exchange with the hot synthesis gas partially and occurs as saturated steam at the liquid level 4 in the steam room 3. When passing through the droplet separator 6 the wet saturated steam is dried. It flows from here dried saturated steam in the annular space 19 between the collar 18th and the guide jacket 11 down and enters through the passage between the lower edge of the guide jacket 11 and the lower Tube plate 8 in the interior enclosed by the guide jacket 11 on.
