Description

本発明はボイラ設備の据付工法に係り、特にそのうちの空気予熱器の据付工法に関する。  The present invention relates to an installation method for boiler equipment, and more particularly to an installation method for an air preheater.

第６図は、発電用の一般的なボイラ設備の概略構成図である。ボイラ本体１は周囲及び上部を鉄骨２で構成されたボイラ建屋３内に配置され、ボイラ建屋３の上部を横切るトップガーダ４より、スリングボルトを介して吊下げられている。  FIG. 6 is a schematic configuration diagram of a general boiler facility for power generation. The boiler body 1 is arranged in a boiler building 3 having a steel frame 2 at the periphery and the upper part, and is suspended from a top girder 4 across the upper part of the boiler building 3 via a sling bolt.

ボイラ本体１への燃焼用２次空気は、押込ファン、空気予熱器５、ウインドボックス６などを経てバーナ上部の火炉燃焼室へと導かれる。また、石炭燃料運搬用空気は、前記空気予熱器５から一次空気ダクト７を経てミル８へ導かれる。  The secondary air for combustion to the boiler body 1 is guided to the furnace combustion chamber at the upper part of the burner through the pushing fan, the air preheater 5, the wind box 6, and the like. Further, the coal fuel carrying air is guided from the air preheater 5 to the mill 8 through the primary air duct 7.

燃料となる石炭はバンカ９に貯留されており、給炭機１０で計量されながらミル８に供給されて、所定の粒径に粉砕される。ミル８で生成された微粉炭は、前記石炭燃料運搬用空気とともにフューエルパイプを通って、ウインドボックス６内に設置されたバーナに供給され、火炉燃焼室で燃焼される。  Coal as fuel is stored in the bunker 9 and is supplied to the mill 8 while being measured by the coal feeder 10 and pulverized to a predetermined particle size. The pulverized coal produced in the mill 8 is supplied to the burner installed in the wind box 6 through the fuel pipe together with the coal fuel carrying air, and burned in the furnace combustion chamber.

火炉燃焼室で燃焼して生成した高温の燃焼ガスは、ボイラ本体１の煙道内に設置されている２次過熱器１１，３次過熱器１２，再熱器１３，１次過熱器１４，節炭器１５などの内部を流通する内部流体と熱交換される。熱交換された燃焼ガスは、節炭器出口ガスダクト１６，脱硝装置，空気予熱器５，空気予熱器出口ガスダクト１７を通って、ボイラ建屋３外の機器へ導かれる。  The high-temperature combustion gas generated by burning in the furnace combustion chamber is a secondary superheater 11, a tertiary superheater 12, a reheater 13, a primary superheater 14, and a section installed in the flue of the boiler body 1. Heat exchange is performed with an internal fluid that circulates inside the charcoal unit 15 or the like. The heat exchanged combustion gas is guided to equipment outside the boiler building 3 through the economizer outlet gas duct 16, the denitration device, the air preheater 5, and the air preheater outlet gas duct 17.

一方、ボイラ本体１への給水はボイラ建屋３外の復水器から主給水管を通って節炭器１５を始めとする前記各種熱交換器へ導かれ、熱交換により高温、高圧の蒸気となり、主蒸気管を通ってボイラ建屋３外の高圧タービンへ導かれる。  On the other hand, the water supply to the boiler body 1 is led from the condenser outside the boiler building 3 to the various heat exchangers such as the economizer 15 through the main water supply pipe, and becomes high-temperature and high-pressure steam by heat exchange. The main steam pipe is led to a high pressure turbine outside the boiler building 3.

中圧タービンからの蒸気は低温再熱蒸気管を介して再熱器１３へと導かれ、再熱された蒸気は高温再熱蒸気管を通ってボイラ建屋３外の低圧タービンへ導かれる。   The steam from the intermediate pressure turbine is led to the reheater 13 through the low temperature reheat steam pipe, and the reheated steam is led to the low pressure turbine outside the boiler building 3 through the high temperature reheat steam pipe.

図７〜図１０は、従来のボイラ設備の据付け工法を説明するための概略構成図である。ケージ下に空気予熱器が配置される構造では、空気予熱器の据付け作業がクリチカルとなっていた。  FIGS. 7-10 is a schematic block diagram for demonstrating the installation method of the conventional boiler equipment. In the structure in which the air preheater is disposed under the cage, the installation work of the air preheater has been critical.

そのため図７に示すように、ボイラ建屋３の建設を行ない、そのボイラ建屋３のトップガーダ４にボイラ本体１を吊り下げる。そしてボイラ建屋３の所定の位置に空気予熱器５の部品１８の吊り込みを行ない、それが終了すると図８に示すように空気予熱器５の上方の鉄骨２部分に仮設の床１９を敷設する。  Therefore, as shown in FIG. 7, the boiler building 3 is constructed, and the boiler body 1 is suspended from the top girder 4 of the boiler building 3. Then, the parts 18 of the air preheater 5 are suspended at a predetermined position of the boiler building 3, and when this is finished, a temporary floor 19 is laid on the steel frame 2 above the air preheater 5 as shown in FIG. .

そして図９に示すように、その床１９を利用して上方のケージ廻りの例えばコイルブロック２０などの吊り上げ搬入を行ない、再熱器１３、１次過熱器１４、節炭器１５などの設置を行なうとともに、床１９の下方では空気予熱器５の設定作業を進めて、図１０に示すようにボイラ設備の据付けを終了する。  Then, as shown in FIG. 9, the floor 19 is used to lift and carry, for example, the coil block 20 around the upper cage, and the reheater 13, the primary superheater 14, the economizer 15, etc. are installed. At the same time, the setting work of the air preheater 5 is advanced below the floor 19 and the installation of the boiler equipment is completed as shown in FIG.

なお、ボイラ設備の据付け工法に関しては、例えば下記のような特許文献を挙げることができる。

JP-A-07-091603 Japanese Patent Laid-Open No. 08-114302 Japanese Patent Laid-Open No. 08-261405 Japanese Patent Laid-Open No. 11-210103 JP 2002-098304 A JP 2002-213707 A

前述のように従来の据付け工法では、空気予熱器５の部品１８の吊り込み作業が完了しないと床１９の敷設ならびに再熱器１３、１次過熱器１４、節炭器１５などの吊り上げ作業を行なうことができず、工期が長引く要因になっていた。  As described above, in the conventional installation method, if the lifting operation of the parts 18 of the air preheater 5 is not completed, the floor 19 is laid and the reheating unit 13, the primary superheater 14, the economizer 15 and the like are lifted. This could not be done, and the construction period was a factor.

また、床１９の仮設により、床１９の上方では前述のような耐圧部の製品の搬入作業を、床１９の下方では空気予熱器５の設定作業を、それぞれ併行して行なっているが、ボイラ建屋３の後方で前述の作業が集中すること、ならびに限られた空間での作業のため、作業能率が悪いという問題がある。  Further, due to the temporary installation of the floor 19, the work of carrying in the product of the pressure-resistant part as described above is performed in parallel above the floor 19, and the setting work of the air preheater 5 is performed in parallel below the floor 19. There is a problem in that work efficiency is poor due to the concentration of the above-described work behind the building 3 and the work in a limited space.

本発明の目的は、このような問題点を解消し、据付け工期を大幅に短縮することが可能なボイラ設備の据付け工法を提供することにある。  An object of the present invention is to provide an installation method for boiler equipment that can eliminate such problems and can greatly shorten the installation period.

前記ボイラ本体内への耐圧部構成部材の組み込みとは別のエリアで前記空気予熱器の組立てを行ない、前記耐圧部構成部材の組み込み終了後に前記空気予熱器をボイラ本体に組み込むことを特徴とするものである。 In order to achieve the above object, the first means of the present invention includes a boiler building composed of a steel frame, an air preheater, and components of a pressure-resistant portion disposed above the air preheater (for example, a reheater, 1 In the installation method of the boiler equipment having the boiler body installed in the boiler building having the following superheater, economizer, etc.,
The air preheater is assembled in an area different from the assembly of the pressure-resistant part constituting member into the boiler body, and the air preheater is incorporated into the boiler body after the assembly of the pressure-resistant part constituting member is completed. Is.

本発明の第２の手段は前記第1の手段において、前記空気予熱器を鉄骨架台上で組み立てて、その空気予熱器を搭載したまま鉄骨架台を前記ボイラ建屋に組み込むことを特徴とするものである。   According to a second means of the present invention, in the first means, the air preheater is assembled on a steel frame, and the steel frame is incorporated in the boiler building while the air preheater is mounted. is there.

本発明の第３の手段は前記第２の手段において、前記空気予熱器を搭載した鉄骨架台を移動台車で前記ボイラ本体の所定位置まで搬入することを特徴とするものである。   According to a third means of the present invention, in the second means, a steel frame mounting the air preheater is carried to a predetermined position of the boiler body by a moving carriage.

本発明の第４の手段は前記第３の手段において、前記空気予熱器を搭載した鉄骨架台を前記移動台車で所定位置まで搬入した後、前記鉄骨架台の支柱をボイラ建屋の基礎部に一体に接合して前記空気予熱器の荷重を前記基礎部で受けてから、前記移動台車を鉄骨架台から外して搬出することを特徴とするものである。   According to a fourth means of the present invention, in the third means, after the steel frame on which the air preheater is mounted is carried to the predetermined position by the movable carriage, the pillar of the steel frame is integrated with the base of the boiler building. After joining and receiving the load of the air preheater at the foundation, the movable carriage is removed from the steel frame and carried out.

本発明は前述のように、ボイラ本体内への耐圧部構成部材の組み込みとは別のエリアで空気予熱器の組立てが併行して行なわれるから、据付け工期の大幅な短縮が図れる。  As described above, according to the present invention, the assembly of the air preheater is performed in an area different from the assembly of the pressure-resistant portion constituting member in the boiler body, so that the installation period can be greatly shortened.

次に本発明の実施形態を図と共に説明する。図１〜図４は、実施形態に係るボイラ設備の据付け工法を説明するための概略構成図である。  Next, an embodiment of the present invention will be described with reference to the drawings. FIGS. 1-4 is a schematic block diagram for demonstrating the installation method of the boiler equipment which concerns on embodiment.
