- Distribute V3 The coolant is discharged from the pipe 36d to the outside of the cooling member 30, and then cooled by the heat exchanger, and is again introduced from the heat exchanger into the pipe 36c.
- the manufacturing method of the gasification burner 1 is demonstrated.
- the cooling member 30 is prepared. Specifically, as illustrated in FIG. 5A, the other end of the inner tube 31 b of the distal end portion 31 is opposed to one end of the intermediate portion 32. In this state, the other end of the inner tube 31b and one end of the intermediate portion 32 are welded. Thereby, as shown in Drawing 5 (b), inner pipe 31b and middle part 32 are joined by welding part W1.
- the male screw Ms provided on the outer peripheral surface of the main body 21 is screwed into the female screw Fs provided on the distal end portion of the inner peripheral surface of the inner tube 31b. Thereby, the nozzle tip 20 is attached to the cooling member 30.
- the fuel pipe 10 is inserted into the through hole of the base end wall 34a and the through hole 21a and the cylindrical hole 22a of the nozzle chip 20.
- tube 10 is fitted with the nozzle chip 20 by clearance fitting.
- the fuel pipe 10 is attached to the nozzle tip 20.
- the inner peripheral surface of the through hole of the base end wall 34 a is welded to the outer peripheral surface of the fuel pipe 10.
- the gasification burner 1 is completed.
- the nozzle tip 20 and the cooling member 30 are screwed together by screws (a male screw Ms and a female screw Fs). Therefore, it is very easy to attach and remove the nozzle tip 20 to the cooling member 30. Therefore, by preparing a plurality of types of nozzle tips 20 with different orientations of the through holes 21b through which the oxidant flows, it is possible to replace the nozzle tips 20 without remodeling the coal gasification furnace 100 and to change the fuel type. It can respond to the change of. As a result, it is possible to cope with various fuel types with a simple configuration.
- a spacer 36a is provided between the inner wall 36 and the distal end wall 31a, and a spacer 36b is provided between the inner wall 36 and the base end portion 35. Therefore, spaces V2 and V3 are secured between the inner wall 36, the distal end wall 31a, and the base end portion 35 by the spacers 36a and 36b. Therefore, it becomes easy for the coolant to flow smoothly in the spaces V2 and V3.
- the tip of the fuel tube 10 is exposed on the tip surface S2 of the nozzle tip 20. Therefore, even if the fuel pipe 10 is thermally expanded due to heat received from the partial oxidation unit 102 during use and extends with respect to the nozzle tip 20, the extension is not regulated by the nozzle tip 20. Therefore, it is possible to suppress unnecessary stress from being generated between the nozzle tip 20 and the fuel pipe 10. Unlike the case where the fuel pipe 10 is attached to the nozzle chip 20 with the tip of the fuel pipe 10 remaining in the nozzle chip 20, the fuel flows through the fuel pipe 10 without contacting the nozzle chip 20. Then, it is discharged into the partial oxidation unit 102. Therefore, the possibility that the nozzle tip 20 is worn due to contact with the fuel can be suppressed.
- the corrosion resistance of the stainless steel deteriorated by the welding of the intermediate portions 32 and 33 and the tip portion 31 is the solution treatment. To recover. Therefore, it becomes possible to further suppress the stress corrosion cracking of the cooling member 30. Since the intermediate portions 32 and 33 and the base end portions 34 and 35 are also joined by welding, if the base end portions 34 and 35 are made of stainless steel, the base end portions 34 and 35 are also deteriorated. To do. However, as shown in FIG. 2, the gasification burner 1 is attached to the partial oxidation unit 102 via the heat insulating material 105, and the heat insulating material 105 covers most of the outer peripheral surface of the cooling member 30. Therefore, the high temperature gas G1 generated in the partial oxidation portion 102 hardly enters the vicinity of the junction between the intermediate portions 32 and 33 and the base end portions 34 and 35.
- the tip of the fuel tube 10 may not be exposed on the tip surface S ⁇ b> 2 of the nozzle tip 20. Specifically, the fuel tube 10 may be attached to the nozzle tip 20 with the tip of the fuel tube 10 remaining in the nozzle tip 20.
- a coating layer 37 may be disposed on the surface of the tip 31 of the cooling member 30.
- the cooling member 30 does not have the intermediate parts 32 and 33, the inner pipe 31b and the base end part 34 are directly joined by the welded part W1, and the outer pipe 31c and the base end part 35 are connected. It is directly joined by the weld W2.
- the covering layer 37 covers a region exposed to the outside of the surface of the distal end portion 31, an outer surface of the welded portion W ⁇ b> 2, and a region near the distal end portion 31 on the outer peripheral surface of the base end portion 35.
- the covering layer 37 may be formed by, for example, building up. Since the coating layer 37 covers the outer surface of the welded portion W2 and the vicinity thereof, the region where the corrosion resistance is deteriorated by welding is protected by the coating layer 37. Therefore, it becomes possible to further suppress the stress corrosion cracking of the cooling member 30.
- the coating layer 37 may be made of a nickel alloy having a Ni content of 40% by mass or more with respect to the total mass of the tip portion 31. Since such a nickel alloy has high corrosion resistance, the coating layer 37 is unlikely to undergo dew point corrosion. Therefore, it becomes possible to further suppress the stress corrosion cracking of the cooling member 30. Examples of such a nickel alloy include Inconel 718, Alloy 718, and the like.
- the distal end portion 31 may be made of copper, and the proximal end portions 34 and 35 may be made of stainless steel.
- copper having high thermal conductivity but low corrosion resistance is covered with the coating layer 37. Therefore, it is possible to suppress the stress corrosion cracking of the tip 31 by the coating layer 37 while promoting heat exchange at the tip 31 that is most susceptible to heat from the partial oxidation portion 102.
- copper is cheaper than stainless steel, the cost of the cooling member 30 can be reduced.
- the thermal expansion coefficient (linear expansion coefficient) of the material constituting the fuel pipe 10 may be larger than the thermal expansion coefficient (linear expansion coefficient) of the material constituting the nozzle tip 20.
- the fuel pipe 10 is made of SUS310S (average linear expansion coefficient of 0 ° C. to 650 ° C. is 17.5 ⁇ 10 ⁇ 6 / ° C.), and the nozzle tip 20 is SUS430 (average linear expansion of 0 ° C. to 650 ° C.).
- the coefficient may be 12.8 ⁇ 10 ⁇ 6 / ° C.).
- the fuel tube 10 and the nozzle tip 20 are thermally expanded by heat received from the partial oxidation unit 102 during use, the fuel tube 10 is firmly attached to the nozzle tip 20 because the thermal expansion coefficient of the fuel tube 10 is larger. Tighten up. Therefore, it is possible to suppress the outflow of the oxidant from the gap between the two.
- the coal gasification furnace 100 using pulverized coal as the fuel has been described as an example.
- the present invention can also be applied to a gasification burner 1 of a plant using fuel other than pulverized coal.
- the present invention can also be applied to a combustion burner used in a combustion furnace that burns pulverized fuel (solid fuel), liquid fuel, or gaseous fuel.

Abstract
Description
まず、本実施形態に係るガス化バーナ1(バーナ)が用いられる設備の一例として、石炭ガス化炉100について、図1を参照して説明する。石炭ガス化炉100は、炉底部101と、部分酸化部102(反応炉)と、熱分解部103(反応炉)とを備える。炉底部101、部分酸化部102及び熱分解部103は、いずれも筒状を呈しており、下方から上方に向かうにつれてこの順に接続されている。
続いて、図2~図4を参照して、ガス化バーナ1の詳細について説明する。ガス化バーナ1は、図2に示されるように、断熱材105を介して部分酸化部102の周壁に取り付けられている。ガス化バーナ1は、図2~図4に示されるように、燃料管10と、ノズルチップ20と、冷却部材30とを備える。
続いて、図5及び図6を参照して、ガス化バーナ1の製造方法について説明する。まず、冷却部材30を用意する。具体的には、図5(a)に示されるように、先端部31の内側管31bの他端と、中間部32の一端とを対向させる。この状態で、内側管31bの他端と中間部32の一端とを溶接する。これにより、図5(b)に示されるように、内側管31bと中間部32とが溶接部W1によって接合される。このとき、内側管31bの他端が外側管31cの他端よりも冷却部材30の基端側に位置しているので、内側管31bの他端と中間部32の一端との間に溶接トーチが向かうことが外側管31cによって妨げられ難い。
以上のような本実施形態では、ノズルチップ20と冷却部材30との間がネジ(雄ネジMs及び雌ネジFs)によって螺合されている。そのため、冷却部材30に対するノズルチップ20の取り付け及び取り外しが極めて容易である。従って、酸化剤が流通する貫通孔21bの向きが異なる複数種類のノズルチップ20を準備しておくことにより、石炭ガス化炉100の改造をすることなくノズルチップ20を交換するだけで、燃料種の変更に対応することができる。その結果、簡易な構成で種々の燃料種に対応することが可能となる。
以上、本開示に係る実施形態について詳細に説明したが、本発明の要旨の範囲内で種々の変形を上記の実施形態に加えてもよい。例えば、図7に示されるように、燃料管10とノズルチップ20とがネジ(雄ネジMs及び雌ネジFs)によって螺合しており、ノズルチップ20と冷却部材30とが嵌合(例えば、隙間嵌め)されていてもよい。また、図8に示されるように、ノズルチップ20と燃料管10とがネジ(雄ネジMs及び雌ネジFs)によって螺合しており、ノズルチップ20と冷却部材30とがネジ(雄ネジMs及び雌ネジFs)によって螺合していてもよい。すなわち、ノズルチップ20と燃料管10との間、及び、ノズルチップ20と冷却部材30との間の少なくとも一方が、ネジによって螺合されていてもよい。
