Then, Fig. 1 is used to cause the appearance to the additional stress of burner 1 to be described to because of generating equipment running.
Generating equipment (not shown) operates, and produces hot-stretch thus in the reacting furnace main body 12 of coal gasifier (reacting furnace) 10 and pressure vessel 11.According to the hot-stretch produced at reacting furnace main body 12 and pressure vessel 11, cause producing poor (hot-stretch is poor) because of the different of the material between reacting furnace main body 12 from pressure vessel 11 and temperature.Therefore, the burner 1 inserted in the lateral reacting furnace main body 12 of pressure vessel 11 be fixed on the side of reacting furnace main body 12 by such as seal box 15 (hereinafter referred to as " base end part ".) running starts, and displacement downwards.
But except the guide barrel expansion piece 5 being arranged on guide barrel 4, be also provided with oxidant pipe expansion piece 7 in oxidant pipe 3, therefore when the base end part of burner 1 is intended to displacement downwards, oxidant pipe expansion piece 7 bends downwards.Thereby, it is possible to relax the bending stress produced at the fixed part of the base end part of oxidant pipe 3, the flange part 3b of oxidant pipe 3 and oxidant pipe 3.
So, the bending stress produced in oxidant pipe 3 is relaxed by oxidant pipe expansion piece 7, but because of burner 1 displacement and cause producing bending stress at cartridge 2 downward.At this, the caliber of cartridge 2 is less than the oxidant pipe 3 and guide barrel 4 forming burner 1, and when comparing with identical curved in length amount, compared with other pipes, the bending stress of generation is little.In other words, produce stress to equal in permission, short length can be managed with other larger than caliber and deal with identical amount of bow.Therefore, according to the burner designated length of the cartridge 2 determined corresponding to the bending stress produced at cartridge 2, the length (length represented by A in Fig. 1) of burner 1 can be determined, thus compared with situation about being selected by oxidant pipe 3, the length of burner can be shortened.
It should be noted that, the spatial portion 13 of coal gasifier (reacting furnace) 10 is full of by the non-oxidizing gas imported from non-oxidizing gas ingress pipe 4c, therefore, it is possible to prevent from flowing into a part in reacting furnace main body 12 there is entering of corrosive generation gas.Therefore, need not worry to cause oxidant pipe 3 and oxidant pipe expansion piece 7 to be corroded because having corrosive generation gas.
As shown in Figure 3, oxidant pipe 3 is located by fixed part 30 relative to reacting furnace main body 12.The mode that this location does not change with the length that the burner leading section 3d of oxidant pipe 3 and cartridge 2 is outstanding in reacting furnace is carried out, and the hot-stretch of the axis of the oxidant pipe 3 produced between fixed part outside the location division 30 (fixed part) of the sidewall in inner side and stove is absorbed by described oxidant pipe expansion piece 7.Because the location division 30 (fixed part) of the sidewall from inner side is little to the length of the stove inside front ends of oxidant pipe 3, therefore this part stove inner shafts to hot-stretch amount minimum, for burning negligible.
As mentioned above, burner 1 involved according to the present embodiment, possess the coal gasifier (reacting furnace) 10 of this burner 1 and possess the generating equipment of this coal gasifier (reacting furnace) 10, playing following action effect.
Possess reacting furnace main body (inner receptacle) 12 and pressure vessel (outer receptacle) 11 coal gasifier (reacting furnace) 10, spatial portion 13 between reacting furnace main body 12 and pressure vessel 11 is filled with non-oxidizing gas and nitrogen, the part (at least partially) being fixed on the bearing of trend of the oxidant pipe 3 of the burner 1 of the sidewall of the reacting furnace main body 12 of coal gasifier (reacting furnace) 10 at base end part arranges oxidant pipe expansion piece (displacement absorption component) 7.Thus, when causing because of the different of the temperature between reacting furnace main body 12 from pressure vessel 11 and material producing hot-stretch difference between reacting furnace main body 12 and pressure vessel 11, oxidant pipe expansion piece 7 can be utilized to absorb because burner 1 is bending and cause bending stress in the bending stress produced in oxidant pipe 3 and cartridge 2, that produce in oxidant pipe 3.In addition, the length (length represented by A in Fig. 1) of burner 1 determined by burner 1 according to the burner designated length of the cartridge 2 determined corresponding to the bending stress produced at cartridge 2.At this, little in the bending stress of the generation forming the cartridge 2 that caliber is minimum among the cartridge 2 of burner 1, oxidant pipe 3 and guide barrel (protection tube) 4.Therefore, compared with determining the existing situation of the length of burner 1 with the bending stress produced based on the oxidant pipe 3 larger than cartridge 2 at caliber, the length of burner 1 can be shortened.Therefore, it is possible to realize the minimizing of burner 1 weight and the raising of maintainability.
Use can shorten the burner 1 of overall length.Therefore, it is possible to reduce the space around the burner 1 being arranged on coal gasifier (reacting furnace) 10.
Use can reduce the coal gasifier (reacting furnace) 10 in the space around burner 1.Therefore, it is possible to realize the minimizing in the space of generating equipment.
Oxidant pipe 3 is fixed by the location division 30 of the sidewall of inner side, and the hot-stretch of the axis of the oxidant pipe 3 produced between fixed part outside the location division 30 (fixed part) of the sidewall in inner side and stove is absorbed by the oxidant pipe expansion piece 7 being arranged on oxidant pipe 3.Because the location division 30 (fixed part) of the sidewall from inner side is little to the length of the stove inside front ends of oxidant pipe 3, therefore this part stove inner shafts to hot-stretch amount minimum, for burning negligible.Thereby, it is possible to suppress the burner leading section 3d hot-stretch significantly of oxidant pipe 3 and change in location occur.Thus, the leading section 3d of burner changes, therefore, it is possible to carry out the burning of stable burner from the position of regulation hardly.In addition, oxidant pipe expansion piece 7 is set in oxidant pipe 3.Thereby, it is possible to the hot-stretch from fixed part 30 oxidant pipe 3 of container 11 side is laterally absorbed by oxidant pipe expansion piece 7.
It should be noted that, in the present embodiment, though to arranging oxidant pipe expansion piece 7 and guide barrel expansion piece 5 is illustrated as displacement absorption component, but the present invention is not limited thereto, also can be can along expansion pieces such as the flexible bellowss of the bearing of trend of oxidant pipe 3 and guide barrel 4.
In addition, the micro-powder fuels such as the fine coal imported in cartridge 2 also can be such as coke, oil, gas etc.
