Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inclined water cooling wall surrounding a furnace of a boiler, and more particularly to a method of assembling an inclined water cooling wall in which the inclined water cooling wall is constituted by an assembly of divided panels. It is about.

[Background of the Invention]

Large-capacity thermal power plants have been constructed to meet the rapidly increasing demand for electric power in recent years, but these boilers are required to transform from supercritical pressure to subcritical pressure in order to obtain high power generation efficiency even under partial load. Is required.

This is because, as a feature of recent electric power demand, the difference between maximum and minimum loads increases along with the growth of nuclear power generation, and thermal power generation tends to shift from base load to load adjustment.

In this way, in thermal power generation, when the operation at partial load increases,
By changing the pressure according to the load, that is, a so-called variable pressure boiler that operates in the supercritical pressure range at full load and in the subcritical pressure range at partial load, the power generation efficiency at partial load can be reduced to several percent. Can be improved.

Therefore, as shown in FIG. 1 and FIG. 2, the structure of the water cooling wall of the boiler furnace is such that the upper part of the furnace 1 is formed by the vertical water cooling wall 2 in which water pipes and fins are alternately welded, and the lower part of the furnace 1 is an inclined water cooling wall (spiral wall). The water cooling wall structure of the combination formed by the furnace wall structure 3 is adopted.

The inclined water cooling wall (spiral furnace wall structure) 3 is a membrane wall in which water pipes and fins are alternately welded like the vertical water cooling wall 2, and the vertical water cooling wall 2 shows this membrane wall in FIGS. 1 and 2. Thus, the furnace 1 is formed by arranging it in a vertical position along with the furnace 1, and the inclined water cooling wall 3 has the membrane wall in a horizontal position as shown in FIG.
In addition, the furnace 1 is formed by obliquely arranging, and as a result, the furnace 1 is spirally wound to form the furnace 1.

In this way, the inclined water cooling wall 3 has a spiral furnace wall structure, and the furnace 1
Since it rises so as to swirl along with, the radiant heat from the furnace 1 can uniformly heat the feed water, and the heat absorption amount differs depending on the installation position of the furnace 1 like the vertical water cooling wall 2. There is no feature. Also, this inclined water cooling wall 3
Is a relatively small number of water tubes compared to the vertical water cooling wall 2
Since it surrounds, the flow velocity of the internal fluid can be increased,
Therefore, there is an advantage that the risk of nucleate boiling and film boiling is small. On the other hand, since the inclined water cooling wall 3 is arranged so as to be inclined with respect to the gravity direction, the strength of the inclined water cooling wall 3 itself is inevitably lower than that of the vertical water cooling wall 2.
For this reason, a back stay (not shown) that surrounds the furnace 1 (a beam horizontally arranged to support the furnace pressure, etc.)
The load of itself cannot be applied to this inclined water cooling wall 3. Further, a support member (vertical strap) 4 is arranged vertically with respect to the inclined water cooling wall 3 as shown in FIGS. This support member (vertical strap) 4
In addition to the role described above, is also used to temporarily support the load of the divided panel 5 when the divided panel 5 is blocked when the inclined water cooling wall 3 is assembled.

Hereinafter, a conventional block construction method for the inclined water cooling wall 3 will be described with reference to FIGS. 3 to 5.

The inclined water cooling wall 3 is manufactured at the factory with the division panel 5 as shown in FIG. 5, and the division panel 5 is transported to the construction site, and the division panel 5 is welded 6 at the construction site as shown in FIG. The boiler furnace 1 is assembled by joining them all together.

For example, as shown in FIG. 4, the division block 5 shown in FIG. 5 has a side wall side division panel 5a, a front wall side division panel 5b, a side wall side division panel 5c, and a rear wall side division panel 5d which are sequentially arranged in a clockwise direction. , These split panels 5a and 5b, 5b and 5
If c, 5c and 5d are connected in the longitudinal direction and the slanting direction by welding 6, the slanted water cooling wall 3 surrounding spirally as shown in FIG. 3 is formed.

Next, a support member (vertical strap) 4 is welded to the vertical water cooling wall 2 and hung down in the direction of gravity.

Hereinafter, the manner in which the inclined water cooling wall 3 is assembled by the split panel 5 will be described with reference to FIGS. 6 to 11.
For convenience of explanation, the case where the side wall side division panel 5a in FIGS. 6 and 7 is connected to the rear wall side division panel 5d will be described as an example.

The rear wall side division panel 5d and the side wall side division panel 5a which have already been assembled are referred to as preceding division panels 5X and 5Y, and the side wall side division panel 5a to be assembled is referred to as a succeeding division panel 5Z.

That is, in the drawings of FIGS. 6 and 7, the right side of the subsequent division panel 5Z is the preceding division panel 5X, and the upper side of the following division panel 5X is the preceding division panel 5Y.

That is, the subsequent split panel 5Z is lifted from the ground to a high place by the wire rope 9 hanging from the boiler steel frame 7 as shown in FIG. 6, and is lifted to the position where the lower portion of the preceding split panel 5Y is shaded. FIG. 7 shows the lifted state.

Then, as shown in FIG. 8, the suspended subsequent split panel 5Z immediately mounts the temporary fastening metal 10 to the subsequent split panel 5Z.

In this state where the subsequent split panel 5Z is suspended at a high place, the temporary fixing metal fitting 10 is welded to the subsequent split panel 5Z by welding 11 as shown in FIG. 8, or a support member (vertical) is used. The subsequent fixing work of the divided panel 5Z is carried out by welding 12 of the strap 4 and the temporary fixing metal fitting 10. However, the series of these works is a dangerous working environment, and the worker himself / herself is at a high place. I was in danger.

Further, in the state in which the succeeding split panel 5Z is temporarily supported by the support member (vertical strap) 4, this time, as shown in FIG. 10 and FIG. On the other hand, the lugs 13a and 13b are welded 1

The support member (vertical strap) 4 supported by 0, welds 11 and 12 is eliminated, and the subsequent division panel 5Z is formed.
The weight of the above is supported by the bolt 17 on the preceding split panel 5Y,
Fine adjustment between the divided panels is performed. When the bolt 17 and nut 18 are suspended as shown in FIG. 10, the provisional fastening member 10 shown in FIGS. 8 and 9 is removed, and the lugs 13a, 13b and the bolt 17, Nuts 18
Thus, the weight of the succeeding division panel 5Z is changed from the support of the supporting member (vertical strap) 4 to the support by the preceding division panel 5Y. Next, the nut 18 is adjusted to finely adjust the positions of the preceding divided panels 5X and 5Y and the succeeding divided panels 5Z.

That is, as shown in FIGS. 8 and 9, the state in which the subsequent split panel 5Z is supported by the support member (vertical strap) 4 by the temporary metal fitting 10 is the same as the upper end of the subsequent split panel 5Z as shown in FIG. It is a rough hanging position between the lower end of the divided panel 5Y and the right end of the succeeding divided panel 5Z and the left end of the preceding divided panel 5X.
The state of being supported by the bolts 17 and nuts 18 and 18 in the figure is a position where fine adjustment work is performed by connecting the preceding split panels 5X and 5Y and the subsequent split panel 5Z by welding 6.

As shown in FIG. 11, the bolt 17 is thus attached to the lugs 13a, 13

Fine adjustment work can be performed between the lower end of 5Y and the upper end of the subsequent split panel 5Z,
After the fine adjustment work is completed, the preceding divided panels 5X and 5Y and the succeeding divided panel 5Z are integrally joined by welding 6 so that the succeeding divided panel 5Z is supported by the preceding divided panels 5X and 5Y.

As described above, before joining the succeeding divided panel 5Z to the preceding divided panel 5X and 5Y by welding 6, the wire rope 9 is used to support the temporary divided metal fitting 10 as shown in FIGS. 8 and 9. It is also supported by the support member 4, on the one hand by the welding 6 on the preceding split panels 5X, 5Y as described above, and on the other hand the bolt 1 between the lugs 13a, 13b.
7, supported by nuts 18, 18, and supported in triple or quadruple, but when the succeeding division panels 5Z are successively joined by welding 6, the suspension by the wire rope 9 is released. The temporary metal fitting 10, the lugs 13a, 13b, etc. are removed by gas cutting.

The following points have been pointed out as problems in the method of assembling the slanted water cooling wall 3 having the above-mentioned structure, and their improvement is desired.

That is, as shown in FIGS. 2 and 4, each divided panel 5 is configured to surround the furnace 1 having a rectangular shape in a plane. Therefore, when assembling, the temporary fixing metal fitting 10 and the support lugs 13a and 13b are attached as described above. , The mounting of the bolt 17, the fine adjustment of the position of the subsequent division panel 5Z, the welding of the division panels 5X, 5Y and 5Z, the temporary fixing metal fitting 10, the support lugs 13a, 13b and the bolt 17 are removed. The entire furnace consumes an extremely large amount of labor and a long time, which is uneconomical.

In addition, the temporary disposition of each of the divided panels 5X, 5Y, 5Z requires the assembling work in an unstable state in which the wire rope 9 is hung, which makes the workability difficult and extremely dangerous.
