Definitions
- the present invention relates to a boiler structure in which the flow rate distribution of a boiler evaporation pipe (furnace water cooling wall) is made appropriate.
- the orifice is provided in the nozzle part of the furnace inlet for the purpose of adjusting the flow rate of the internal fluid described above.
- an orifice is installed in the nozzle section of the inlet header that exists for each furnace wall, and this orifice matches the heat load distribution in the furnace wall.
- the flow rate is adjusted for each boiler evaporator tube.
- it is effective to reduce the friction loss from the inlet header to the outlet header for each furnace wall in order to ensure the flow rate stability of the internal fluid flowing in each water-cooled wall surface of the furnace water-cooled wall.
- the conventional orifice diameter is set so as to correct the pressure loss difference for each furnace wall divided into a plurality of parts. For this reason, the pressure loss from the furnace inlet header to the outlet header tends to decrease the orifice diameter in accordance with the adjustment of the pressure loss difference, so that the increase in pressure loss due to the orifice increases. That is, in the conventional orifice, in addition to the flow rate adjustment for each boiler evaporator tube in accordance with the heat load distribution in the furnace water cooling wall, the difference in system path pressure loss that differs for each furnace wall is also adjusted. There is room for improvement in that the pressure loss of the entire furnace water cooling wall, including the pressure loss, becomes higher than the ideal state.

- Each of the first pressure loss adjustment unit and the second pressure loss adjustment unit may perform desired pressure loss adjustment in a plurality of stages according to the situation such as the flow path diameter to be installed.
- the first pressure adjustment unit performs individual adjustment of a fixed orifice inserted into the distribution pipe, a thick short pipe section having the same outer diameter inserted into the distribution pipe, and a pressure loss generated in the distribution pipe.
- the fixed orifice inserted in the outlet connecting pipe can adjust the pressure loss by changing the orifice diameter.
- the thick short tube portion having the same outer diameter inserted into the outlet connecting pipe is a pipe material whose inner diameter is reduced by increasing the wall thickness, and the pressure loss can be adjusted by changing the inner diameter and length.
- the pressure loss can be adjusted by changing at least one of the inner diameter, the number and the flow path length of the tube material constituting the outlet connecting pipe.
- the flow rate distribution to the furnace water cooling wall is such that the first pressure loss adjusting unit and the second pressure loss adjusting unit provided on the upstream side of the furnace water cooling wall play different roles, respectively. Can be distributed appropriately without excessively increasing the value.

Abstract
Description
このため、管台部に設置したオリフィスによる流量調整は、各火炉壁内におけるボイラ蒸発管毎の流量分布調整のみを目的とした圧損調整が可能であれば、すなわち、ボイラ蒸発管毎の流量調整のみに基づいたオリフィス径の設定が可能であれば、上述した入口ヘッダから出口ヘッダまでの間に生じる各火炉壁毎の圧力損失が過大になることはない。
本発明は、上記の事情に鑑みてなされたものであり、その目的とするところは、複数に分割した火炉壁面(各火炉壁)への内部流体の流量配分について、圧力損失を過大にすることなく適正に分配し、火炉入口ヘッダから出口ヘッダまでの間に生じる圧力損失(摩擦損失)の低減が可能になるボイラ構造を提供することにある。
本発明の一態様に係るボイラ構造は、火炉の壁面に配設された多数のボイラ蒸発管が火炉水冷壁を形成し、前記ボイラ蒸発管に圧送された水が管内部を流れる際に前記火炉内で加熱されて蒸気を生成するボイラ構造において、前記火炉水冷壁を複数に分割した各火炉壁の入口ヘッダへ水を導く分配管に設けられた内部流体の第1圧力損失調整部と、前記入口ヘッダから前記ボイラ蒸発管へ水を導く管台部に設けられた第2圧力損失調整部と、を備えている。
第1圧力損失調整部及び第2圧力損失調整部は、設置する流路径等の状況に応じて、各々が複数段階に分けて所望の圧力損失調整を行うようにしてもよい。
ここで、出口連絡管に挿入した固定オリフィスは、オリフィス径を変化させて圧力損失を調整することができる。
出口連絡管に挿入した同外径の厚肉短管部は、肉厚を増すことで内径を小さくした管素材であり、その内径や長さを変化させて圧力損失を調整することができる。
出口連絡管に生じる圧力損失の個別調整は、出口連絡管を構成する管素材の内径、本数及び流路長さについて、少なくともひとつを変化させて圧力損失を調整することができる。
この結果、内部流体が流れる火炉入口ヘッダから出口ヘッダまでの間においては、内部流体の流れによって生じる圧力損失(摩擦損失)を低減することができる。従って、火炉水冷壁内における内部流体の流動安定性及び自然循環力が向上し、信頼性の高いボイラ構造を提供できるという顕著な効果が得られる。
<第1の実施形態>
図1及び図2に示す実施形態において、ボイラ1は、火炉2の壁面に配設された多数のボイラ蒸発管3が火炉水冷壁4を形成し、ボイラ蒸発管3に圧送された水が管内部を流れる際、火炉2の内部で水が加熱されて蒸気を生成するように構成された超臨界変圧貫流ボイラである。図示のボイラ1は、火炉2の水平断面が矩形状とされ、前後左右の4面に分割された各火炉壁により火炉水冷壁4が形成され、たとえば図1に示すように、各火炉壁が出口連絡管10を介して天井水冷壁5に接続されている。
図1において、火炉水冷壁4は、左側壁4A、前壁4B、右側壁4Cの各火炉壁に4分割されている。
入口ヘッダ21の管台部には、上下方向に延びて火炉壁4を形成する多数のボイラ蒸発管3が接続されている。
上述したボイラ蒸発管3の各入口部には、入口ヘッダ21から各ボイラ蒸発管3へ水を導く管台部に、第2圧力損失調整部としてオリフィス23が設けられている。このオリフィス23は、火炉水冷壁4内の熱負荷分布に合わせた流量調整を行うため、ボイラ蒸発管3毎に異なる所望のオリフィス径に設定された固定オリフィスが使用される。
すなわち、火炉水冷壁4を複数に分割した各火炉壁の入口ヘッダ21に水を導く入口連結管20に設けられたオリフィス22は、複数に分割した水冷壁毎の圧力損失差を是正し、かつ、入口ヘッダ21から各ボイラ蒸発管3へ水を導く管台部に設けられたオリフィス23は、火炉水冷壁4内の熱負荷分布に合わせたボイラ蒸発管3毎の流量調整をするというように、二段階のオリフィス22,23を設けて、それぞれが異なる流量調整を行うように役割分担させている。
なお、上述した実施形態のオリフィス22,23については、設置する流路径等の状況に応じて、各々を複数の段階に分けて、すなわち複数段のオリフィスを直列に配置して所望の圧力損失調整を行うようにしてもよい。
この変形例では、第1圧力損失調整部のオリフィス22に代えて、入口連結管20に同外径の厚肉短管部24が挿入されている。この厚肉短管部24は、水の状態にある内部流体が厚肉短管部24を通過して生じる圧力損失により、各火炉壁に対する流量配分を最適に調整している。この場合の厚肉短管部24は、入口連結管20と同外径を有し、肉厚を増すことで内径を小さくした管素材が使用される。すなわち、厚肉短管部24の内径や長さを変化させることにより、圧力損失を調整することができる。
この変形例では、第1圧力損失調整部のオリフィス22に代えて、各入口連結管20を内部流体が流れて生じる圧力損失の個別調整が採用されている。すなわち、図中に太線で示す各入口連絡官20について、入口連絡官20を構成する管素材の内径、本数及び流路長さについて、少なくともひとつを変化させて圧力損失を調整している。
図5から図7に示す実施形態においては、4分割された左側壁4A、前壁4B、後壁4C及び右側壁4Cに加えて、さらに、後壁6を3分割した火炉水冷壁6A,6B,6Cが設けられている。
節炭器から後壁6に供給された水は、火炉水冷壁4と同様に加熱を受けて二相流または蒸気の内部流体となる。この内部流体は、後壁6と天井水冷壁5の下流とを連結する出口連絡官30を通り、途中の副側壁管7を経由して火炉水冷壁4で生成された蒸気に合流する流路系統と、追加水冷壁6と天井水冷壁5の下流とを連結する出口連絡官31を通り、途中の後壁吊下管8を経由して火炉水冷壁4で生成された蒸気に合流する流路系統とに分かれる。
図5に示す実施形態は、入口連絡官20に設ける第1圧力損失調整部として、圧力損失の個別調整が採用されている。すなわち、水が流れる入口連絡管20を構成する管素材の内径、本数及び流路長さについて、少なくともひとつを変化させて圧力損失を調整している。
図7に示す本実施形態の第2変形例は、入口連絡官20に設ける第1圧力損失調整部として、内部流体が水である入口連絡管20の途中に挿入するオリフィス22を採用している。すなわち、入口連絡管20を構成する管素材の途中にオリフィス22を挿入し、そのオリフィス径を適宜変化させて圧力損失を調整している。
なお、図5から図7に示す第1圧力調整部は、入口連絡官20等における圧力損失の個別調整、厚肉短管部24の挿入及びオリフィス22の挿入について、いずれか1つを単独採用するだけでなく、複数を適宜組み合わせてもよい。
この結果、内部流体が流れる火炉2の入口ヘッダ21から出口ヘッダまでの間においては、内部流体の流れによって生じる圧力損失(摩擦損失)を低減することができる。従って、火炉水冷壁4内における内部流体の流動安定性及び自然循環力が向上し、信頼性の高いボイラ構造を提供することができる。
本発明は上述した実施形態に限定されることはなく、その要旨を逸脱しない範囲内において適宜変更することができる。
