Description

本発明は、固形物含有高温ガスを冷却するための廃熱ボイラに関する。   The present invention relates to a waste heat boiler for cooling a solid-containing high-temperature gas.

このような廃熱ボイラは、米国特許出願公開第２００６０７６２７２号明細書に記載されている。この公報は、縦長のガス化反応器で行われる代表的な石炭ガス化プロセスを記載している。ガス化反応器によって排出される際に、高温ガスは、廃熱ボイラ内で下方に流れるために１８０°偏向される必要がある。米国特許出願公開第２００６０７６２７２号明細書の設計では、高温ガスの偏向は、水平線に対して約４５°の曲がりダクト部分によって、およびそれに続くガスが１３５°偏向されるガス反転室によって行われる。ガス反転室は、廃熱ボイラの上端部に存在する。   Such a waste heat boiler is described in US Patent Publication No. 20060762272. This publication describes a typical coal gasification process performed in a vertically long gasification reactor. When exhausted by the gasification reactor, the hot gas needs to be deflected 180 ° in order to flow downward in the waste heat boiler. In the design of U.S. Pat. Appl. No. 2006076272, hot gas deflection is effected by a bent duct section of about 45 ° with respect to the horizon, followed by a gas reversing chamber where the gas is deflected 135 °. The gas reversing chamber exists at the upper end of the waste heat boiler.

米国特許出願公開第２００６０７６２７２号明細書US Patent Application Publication No. 20060762272

先行技術の設計のガス化形態の欠点は、運転時に、固形物が、廃熱ボイラに存在するような冷却表面、および冷却表面の支持構造に蓄積され得ることである。   A disadvantage of the gasification form of the prior art design is that during operation, solids can accumulate on the cooling surface as present in the waste heat boiler and on the support structure of the cooling surface.

本発明は、改善された廃熱ボイラを提供することを目的としている。これは、次に述べる廃熱ボイラによって達成される。   The object of the present invention is to provide an improved waste heat boiler. This is achieved by a waste heat boiler described below.

廃熱ボイラは、高温ガス用の同軸に配置された管状チャンネルを備える縦長の容器であり、前記管状チャンネルには高温ガス用の入口および冷却ガス用の出口がさらに設けられ、
ガス経路が、前記管状チャンネルの前記入口と前記出口との間に画定され、ガス経路には、１つまたは複数の管状の冷却表面の束が存在し、前記管状の冷却表面がチャンネルと同軸に配置され、
管状チャンネルは、一方の端部で閉鎖され、それによってガス反転室を形成し、ガス入口が、ガス反転室とガス経路との間に配置される管状チャンネルの壁に設けられた開口であり、高温ガス用の入口は、入口導管に接続され、その導管は、前記管状チャンネルと角度αで配置され、
管状チャンネルの高温ガス入口に、ダイバータ板が存在する。 The waste heat boiler is a vertically long container including a coaxially arranged tubular channel for hot gas, and the tubular channel is further provided with an inlet for hot gas and an outlet for cooling gas,
A gas path is defined between the inlet and the outlet of the tubular channel, the gas path includes a bundle of one or more tubular cooling surfaces, and the tubular cooling surface is coaxial with the channel. Arranged,
The tubular channel is closed at one end, thereby forming a gas reversing chamber, the gas inlet being an opening provided in the wall of the tubular channel disposed between the gas reversing chamber and the gas path; The hot gas inlet is connected to an inlet conduit, which is arranged at an angle α with the tubular channel;
A diverter plate is present at the hot gas inlet of the tubular channel.

出願人らは、このような板が存在していることによって、ガスが廃熱ボイラを通してより均一に流れることを見出している。ガス速度がより均一であるので、ほとんどいかなる淀み流れも存在せず、したがって、固形物は、冷却表面および冷却表面の支持構造に蓄積する機会を有さず、したがって、より良好な熱伝達が生じる。   Applicants have found that the presence of such plates allows the gas to flow more uniformly through the waste heat boiler. Because the gas velocity is more uniform, there is almost no stagnation flow, so the solids have no opportunity to accumulate on the cooling surface and the cooling surface support structure, and therefore better heat transfer occurs. .

本発明は、図１から図２を使用することによってさらに説明される。   The invention is further illustrated by using FIGS. 1-2.

本発明による廃熱ボイラの上端部を示す図である。It is a figure which shows the upper end part of the waste heat boiler by this invention. 図１の断面図ＡＡ’を示す図である。It is a figure which shows sectional drawing AA 'of FIG.

図１は、縦長の容器（３）である廃熱ボイラ（２）の上端部（１）を示している。容器（３）は、高温ガス用の同軸に配置された管状チャンネル（４）を備える。チャンネル（４）には、高温ガス用の入口（５）、および容器（３）の下端部のところの冷却ガス用の出口（この図では図示せず）が設けられる。ガス経路（６）は、前記管状チャンネルの前記入口（５）と前記出口との間に画定される。ガス経路（６）には、１つまたは複数の管状の冷却表面の束（７）が存在する。管状の冷却表面の束（７）は、チャンネルと同軸に配置される。管状チャンネル（４）は、一方の端部（８）で閉鎖され、それによってガス反転室（９）を形成する。ガス入口（５）は、ガス反転室（９）とガス経路（６）との間に配置される管状チャンネル（４）の壁（１０）に設けられた開口である。高温ガス用の入口（５）は、入口導管（１１）に接続され、その導管は、前記管状チャンネル（４）と角度αで配置される。角度αは、３０°と９０°との間であることが好ましい。これらの好ましい角度の場合、使用時に入口導管（１１）を通して流れながら高温ガスは、ガス経路（６）の中に流れるときに９０°よりも大きな曲がりを作ることになる。上述されたような廃熱ボイラ（２）の例は、前述の米国特許出願公開第２００６０７６２７２号明細書に記載されている。   FIG. 1 shows an upper end portion (1) of a waste heat boiler (2) which is a vertically long container (3). The container (3) comprises a coaxially arranged tubular channel (4) for hot gas. The channel (4) is provided with an inlet (5) for hot gas and an outlet for cooling gas (not shown in this figure) at the lower end of the vessel (3). A gas path (6) is defined between the inlet (5) and the outlet of the tubular channel. There is one or more tubular cooling surface bundles (7) in the gas path (6). A bundle of tubular cooling surfaces (7) is arranged coaxially with the channel. The tubular channel (4) is closed at one end (8), thereby forming a gas reversal chamber (9). The gas inlet (5) is an opening provided in the wall (10) of the tubular channel (4) disposed between the gas reversing chamber (9) and the gas path (6). The hot gas inlet (5) is connected to an inlet conduit (11), which is arranged at an angle α with the tubular channel (4). The angle α is preferably between 30 ° and 90 °. For these preferred angles, hot gas flowing through the inlet conduit (11) in use will make a bend greater than 90 ° when flowing into the gas path (6). An example of the waste heat boiler (2) as described above is described in the aforementioned US Patent Application Publication No. 20060762272.

また、図１は、管状チャンネル（４）の高温ガス入口（５）のところの追加のダイバータ板（１２）を示している。このような板は、ガス流れを均一にし、したがって熱伝達を増加させることによって流れパターンを改善するために、米国特許出願公開第２００６０７６２７２号明細書の廃熱ボイラに加えられ得ることが有利である。高温ガス入口（５）の語句によって、その所期の適用に使用される場合にそうであるように、容器（３）が垂直に配置されるときに同じ高さにあることが意味される。このようにして、管状チャンネル（４）に入るガスのうちの少なくともいくらかは、使用時に前記ダイバータ板（１２）に衝突することになる。ダイバータ板（１２）は、図１に示されるように、ダイバータ板の頂部を、流入する高温ガスの流れから遠ざかる方向に回転させて、管状チャンネル（４）の長手方向軸に対して５°と４５°との間の角度βで配置されることが好ましい。ダイバータ板（１２）は、管状チャンネル（４）の長手方向軸に対して、より好ましくは１０°と２５°との間の角度βで、さらにより好ましくは１５°の角度βで配置される。好ましい実施形態では、角度βは変更され得る。板は、ガス経路（６）に向かって流れる高温ガス用の少なくとも２つの主ガス進入経路（１３および１４）が形成されるように、管状チャンネル内に寸法および位置を有することが好ましい。４つのガス進路が形成されることが好ましい。１つの主ガス進入経路（１３）は、ガス反転室（９）を介して延び、１つの主ガス進入経路は、ガス入口（５）およびガス経路（６）を直接接続する開口（１５）を介して延びる。２つの他のガス進路（２０ａおよび２０ｂ）は、図２に示されるように板の左側および右側にある。   FIG. 1 also shows an additional diverter plate (12) at the hot gas inlet (5) of the tubular channel (4). Such a plate can be advantageously added to the waste heat boiler of U.S. Patent Publication No. 20060762272 to improve gas flow and thus improve flow patterns by increasing heat transfer. . The phrase hot gas inlet (5) means that the container (3) is at the same height when placed vertically, as it would be when used in its intended application. In this way, at least some of the gas entering the tubular channel (4) will impinge on the diverter plate (12) in use. As shown in FIG. 1, the diverter plate (12) rotates the top of the diverter plate in a direction away from the flow of the incoming hot gas to 5 ° with respect to the longitudinal axis of the tubular channel (4). It is preferably arranged at an angle β between 45 °. The diverter plate (12) is arranged with respect to the longitudinal axis of the tubular channel (4), more preferably at an angle β between 10 ° and 25 °, and even more preferably at an angle β of 15 °. In preferred embodiments, the angle β can be varied. The plates preferably have dimensions and positions in the tubular channel so that at least two main gas entry paths (13 and 14) for hot gas flowing towards the gas path (6) are formed. Four gas paths are preferably formed. One main gas entry path (13) extends through the gas reversing chamber (9), and one main gas entry path has an opening (15) directly connecting the gas inlet (5) and the gas path (6). Extending through. Two other gas paths (20a and 20b) are on the left and right sides of the plate as shown in FIG.

板（１２）には、冷却手段が設けられることが好ましい。冷却手段は、図２に示されるように冷却媒体用の入口（１７）および出口（１８）を有する１つまたは複数の導管（１６）であることがより好ましい。適切な冷却媒体は、冷水または沸騰水である。板（１２）は、支持ロッド（２１）によって適切に支持される。支持ロッド（２１）は、好ましい長方形の板（１２）の４つの縁に適切に固定される。   The plate (12) is preferably provided with cooling means. More preferably, the cooling means is one or more conduits (16) having an inlet (17) and outlet (18) for the cooling medium as shown in FIG. A suitable cooling medium is cold or boiling water. The plate (12) is suitably supported by the support rod (21). The support rod (21) is suitably secured to the four edges of the preferred rectangular plate (12).

板（１２）には、運転中に蓄積され得るいかなる固形物も除去するように１つまたは複数の機械的洗浄手段（１９）またはブラスタが適切に設けられ得る。板（１２）の表面には、耐火材の層またはクラッディングが適切に設けられ得る。   The plate (12) may suitably be provided with one or more mechanical cleaning means (19) or blasters to remove any solids that may accumulate during operation. The surface of the plate (12) may suitably be provided with a layer of refractory material or cladding.

廃熱ボイラ（２）内のガス流れの均一性は、ダイバータ板（１２）がある場合とない場合で測定され、解析された。ガスの速度分布は、管状の冷却表面の束（７）の上方に０．５メートルの管状の冷却表面の束（７）に直角な水平面に沿って、および管状の冷却表面の束（７）の中に０．５メートルの管状の冷却表面の束（７）に直角な水平面に沿って測定された。   The uniformity of gas flow in the waste heat boiler (2) was measured and analyzed with and without the diverter plate (12). The velocity distribution of the gas is along the horizontal plane perpendicular to the 0.5 meter tubular cooling surface bundle (7) above the tubular cooling surface bundle (7) and the tubular cooling surface bundle (7). Was measured along a horizontal plane perpendicular to the bundle (7) of tubular cooling surfaces of 0.5 meter in.

ガス速度分布は、速度の大きさの標準偏差、または平均からの速度偏差の二乗平均（ＲＭＳ）によって最もよく特徴づけられる。ＲＭＳは、変数がその平均値の周りにいかに多く変化するかを評価するための標準的な統計的方法であり、当業者にはよく知られている。   The gas velocity distribution is best characterized by the standard deviation of velocity magnitude, or the root mean square (RMS) of velocity deviation from the mean. RMS is a standard statistical method for assessing how much a variable changes around its mean value and is well known to those skilled in the art.

ダイバータ板（１２）を使用しない場合、管状の冷却表面の束（７）の頂部の上方に０．５メートルのところのガス速度分布のＲＭＳ値は、３７．４％であり、２０°の角度βで配置されたダイバータ板（１２）を使用した場合、ＲＭＳ値は、５．２％であり、１５°の角度βで配置されたダイバータ板（１２）を使用した場合、ＲＭＳ値は、５．６％であり、両方は、ダイバータ板（１２）が使用されなかった場合と対照してガス速度分布についてほぼ７倍の改善を示した。   Without the diverter plate (12), the RMS value of the gas velocity distribution at 0.5 meters above the top of the tubular cooling surface bundle (7) is 37.4%, an angle of 20 ° When the diverter plate (12) arranged at β is used, the RMS value is 5.2%, and when the diverter plate (12) arranged at an angle β of 15 ° is used, the RMS value is 5%. .6%, both showed almost a 7-fold improvement in gas velocity distribution compared to when the diverter plate (12) was not used.

ダイバータ板（１２）を使用しない場合、管状の冷却表面の束（７）の頂部の下方に０．５メートルのところのガス速度分布のＲＭＳ値は、８．５％であり、２０°の角度βで配置されたダイバータ板（１２）を使用した場合、ＲＭＳ値は、４．０％であり、１５°の角度βで配置されたダイバータ板（１２）を使用した場合、ＲＭＳ値は、３．７％であり、両方は、ダイバータ板（１２）が使用されなかった場合と対照してガス速度分布について２倍を超える改善を示した。   Without the diverter plate (12), the RMS value of the gas velocity distribution at 0.5 meters below the top of the tubular cooling surface bundle (7) is 8.5%, an angle of 20 ° When the diverter plate (12) arranged at β is used, the RMS value is 4.0%, and when the diverter plate (12) arranged at an angle β of 15 ° is used, the RMS value is 3 0.7%, both showing more than a 2-fold improvement in gas velocity distribution compared to when the divertor plate (12) was not used.

したがって、ダイバータ板（１２）を使用すると、管状の冷却表面の束（７）の上方でもその内部でもガス速度の均一性が実質的に増加した。   Thus, the use of the diverter plate (12) substantially increased the uniformity of gas velocity above and within the tubular cooling surface bundle (7).
