Definitions
- This invention relates generally to gasification systems, and more specifically, to methods and systems for fabricating syngas cooler platens.
- At least some known gasification systems convert a mixture of fuel, air or oxygen, steam, and/or limestone into an output of partially combusted gas, sometimes referred to as "syngas".
- the hot combustion gases are supplied to the combustor of a gas turbine engine, which powers a generator used to supply electrical power to a power grid.
- Exhaust from at least some known gas turbine engines is supplied to a heat recovery steam generator that generates steam for driving a steam turbine. Power generated by the steam turbine may also be used to drive an electrical generator that provides electrical power to the power grid.
- some known gasification systems recover heat from the syngas to generate additional steam for powering the steam turbine.
- the steam is generated by passing the syngas over the platens of a syngas cooler.
- the platens are arrays of boiler tubes that create steam as heat is transferred from the syngas to boiler feedwater flowing within the boiler tubes.
- some known platen designs may provide only limited radiant and convective heat extraction because solids within the syngas become deposited on the surface of the platens. Accordingly, heat transfer from the syngas to the boiler feedwater may be reduced and, thus, steam production may be limited.
- One known method for preventing excessive deposits of the solids within the syngas includes orienting the tubes of the platens in a vertical fashion and spacing the tubes a distance from a centerline of syngas flow.
- Such designs are often cost prohibitive and/or increase the size and/or weight of the syngas cooler.
- a method for fabricating a syngas cooler includes coupling a tube cage within the syngas cooler, and coupling a plurality of platens to the tube cage to facilitate steam production in the syngas cooler.
- At least a first platen has at least one of a length that is larger than a length of a second platen, a non-linear geometry, and an angular position that is oblique with respect to a wall of the syngas cooler.
- a syngas cooler in another aspect, includes a tube cage and a plurality of platens coupled to the tube cage to facilitate steam production in the syngas cooler. At least a first platen has at least one of a length that is larger than a length of a second platen, a non-linear geometry, and an angular position that is oblique with respect to a wall of the syngas cooler.
- a plurality of platens are provided.
- the platens are configured to couple to a tube cage of a syngas cooler to facilitate steam production in the syngas cooler.
- At least a first platen has at least one of a length that is larger than a length of a second platen, a non-linear geometry, and an angular position that is oblique with respect to a wall of the syngas cooler.
- FIG. 1 is schematic view of an exemplary integrated gasification combined cycle (IGCC) system
- Figure 2 is a schematic cross-sectional view of an exemplary syngas cooler that may be used with the system shown in Figure 1;
- Figure 3 is an exemplary embodiment of a plurality of platens that may be used with the syngas cooler shown in Figure 2;

- Figure 13 is another alternative embodiment of a plurality of platens that may be used with the syngas cooler shown in Figure 2.
- the present invention provides a plurality of platens for use in a syngas cooler, wherein at least one platen either has a length that is longer than the length of a second platen, has a non-linear geometry, and/or is coupled to a tube cage of the syngas cooler at an oblique angle with respect to a wall of the syngas cooler.
- the present invention provides various configurations in which the known geometric shape of platens is modified from a uniformly straight, radially positioned construction to a different geometric configuration wherein different numbers, angles, and/or lengths of the platens are used.
- the different platen designs described herein facilitate enhancing radiant and convective heat extraction between the syngas and the boiler feed water within the tubes of the platens.
- platen configurations facilitate the design of a more compact and/or cost effective syngas cooler.
- the present invention is described with respect to platens that may be used in a syngas cooler, one of ordinary skill in the art should understand that the present invention is not limited to being used only in syngas coolers. Rather, the present invention may be used in any system that utilizes heat exchange. Further, for simplicity, the present invention is described herein only with respect to producing steam as a by-product of syngas production. However, as would be appreciated by one of ordinary skill in the art, the present invention is not limited to producing steam; but rather, the present invention may be used to produce any byproduct of heat exchange.

- Carbon dioxide (CO2) may be separated from the syngas during clean-up and, in the exemplary embodiment, may be vented to the atmosphere.
- Gas turbine engine 20 drives a generator 34 that supplies electrical power to a power grid (not shown).
- Exhaust gases from gas turbine engine 20 are channeled to a heat recovery steam generator 36 that generates steam for driving steam turbine 22.
- Power generated by steam turbine 22 drives an electrical generator 38 that provides electrical power to the power grid.
- steam from heat recovery steam generator 36 is supplied to gasifier 16 for generating syngas.
- system 10 includes a pump 40 that supplies boiled water from steam generator 36 to syngas cooler 18 to facilitate cooling the syngas channeled from gasifier 16.
- the boiled water is channeled through syngas cooler 18 wherein the water is converted to steam.
