ペースを図ったものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the structure of a vertical furnace tube smoke tube boiler, and more specifically, it improves thermal efficiency and extends the life of the boiler by eliminating the passage path for high-temperature combustion gas generated within the furnace tube. It is designed to take up a small space.

A plurality of smoke pipes 3 are attached to the upper part of the furnace tube 2, and the furnace 2 is also heated by the flame of
Heat it up and smoke the combustion residue! ! The heat medium (hereinafter referred to as can water) 7 stored in the can +1-11 is heated by passing it through i'3. The steam generated from the heated canned water 7 is steam 8
is supplied to the user side via
L The combustion residue is further pushed out from the smoke chamber 6 upwards.

ところで缶水７の中には種々の不純物等が含まれている
ためボイラの各部にはｉ＋ｊ木の濃縮によって生成され
るスケール分が堆積付着することは避けられない。By the way, since the canned water 7 contains various impurities, it is inevitable that the scale produced by the concentration of i+j wood will accumulate and adhere to various parts of the boiler.

。Such scales are found on horizontal surfaces inside the can, such as the furnace tube 2.
A particularly large amount tends to accumulate on the first side 2a of the furnace cylinder 2 and on the side peripheral wall 2b of the furnace cylinder 2. In this way, (I' L) scale seriously impairs the heat transfer effect of the boiler and overheats the occupied part.Furthermore, due to the buildup of these scales, the potential difference generated on the entire surface causes corrosion. In addition, in this type of boiler, the storage height of the canned water 7 is maintained at the width WL shown in the figure, so the upper part 3a of the smoke pipe 3 is exposed to the steam chamber, causing overheating damage. In addition, the contact area between the canned water 7 and the smoke pipe 3 is small, resulting in low thermal efficiency.

本発明は以上の様な車情に若目して種々研究の結果なさ

とするものである。In other words, the structure of the present invention that achieves the above object is that a vertical furnace tube with a smaller diameter than the can body is arranged inside a steam boiler in the form of a platform, and a vertical furnace tube with a diameter smaller than the can body is arranged along the vertical furnace tube below the furnace tube. A plurality of smoke pipes are arranged from the wall toward the ceiling of the can body, and a burner is provided on the ceiling of the furnace cylinder so that combustion residue is discharged from the bottom of the furnace cylinder through the smoke pipes. The main points are as follows.

に配置１ジしたドーナツ状連室１６に接続されている。DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration and effects of the present invention will be specifically explained below based on the drawings of the embodiments. FIG. 2 is a schematic explanatory diagram showing the vertical furnace tube boiler of the present invention, and FIG. 3 is a sectional view taken along the line ■--■ in FIG. 2. In other words, in the illustrated smoke tube boiler, there is a gap 17 inside the vertical cylindrical can ff111 where canned water should enter.
The furnace cylinder 12 is installed upright parallel to the cans ll-l1l, leaving the bottom part 12a of the furnace cylinder 12 at the upper end of the furnace cylinder 12.
Combustion device 15 arranged in four layers so as to inject flame toward
is taken/one is taken. However, the flame injection force itself is not part of the present invention. A large number of flue pipe connection holes 14a are provided along the circumferential direction on the lower side of the vertical III+2 surface 14 of the furnace cylinder 12, and the connection holes 14a are provided with the gap 17 toward the ceiling 11a of <1iIII→11. A large number of smoke pipes 13 are installed, and the upper ends of these smoke pipes 13 are connected to a doughnut-shaped continuous chamber 16 arranged on the upper surface side of the ceiling part 11a.

熱障害を受けない様に連転制御する。Therefore, the combustion gas generated along with the flame injected from the J]1lI-L section of the furnace tube 12 toward the lower blade flows into the smoke pipe 13 from the lower side of the furnace tube 12, and then flows into the smoke '613.
It is collected in a continuous room 16, and then from the continuous room 16, it passes through an economizer and the like and is shipped out from a chimney. On the other hand, is there any brackish water taken out from the ceiling 11a of the r-body 11? 618a is attached, and the 1 end of the brackish water outlet pipe 18a opens above the gap 17, that is, into the 1st part 17a, and the 1' (water mixture) generated in the can +1-111 is introduced into the Yagi separator 18. Then, the air is sent out from the steam valve j18c to the user side, and the water that has been separated is sent back to the can Irl1l via the precipitation wtab.Also, <1111 No. 1
<11 The water level is maintained at a higher level than the flame nozzle 15a of the combustion device 15, and the straight wall surface of the furnace tube 12, which is heated by the combustion flame, is exposed above the water surface. Continuous control is performed to prevent overheating failure.

Since the flame ejected from 5 can heat the entire vertical wall surface of the furnace tube 12 formed in one direction, the heat transfer effect on the surface of the furnace f,';)l 2 is extremely good. Run inside the furnace tube 12 from one side toward the lower blade (1
Since the burned scum passes through the smoke tube 13 from below the furnace i', 312 and moves 1-yl, the heat transfer area (area) by the smoke tube 3 becomes large, and the heat transfer in the smoke tube 13 is effectively improved. 1. In this way, the entire length L1 of the furnace tube 12 and almost the entire length of the smoke t613 can be used as a heat transfer portion, so the thermal efficiency is extremely high. In addition, the high temperature gas population part of the smoke pipe 13 is the furnace tube 1.
Since it is formed to be attached to the straight wall surface of No. 2, it is difficult for scale to adhere to the wall, and overheating and corrosion will not occur.

A smoke pipe 13a may be installed, as long as the scale contained in the fluid avoids water leakage near the smoke pipe 13, 1.3a and the smoke pipe'6 connection part. Either is fine. In addition, the smoke tubes 13 taken out radially from the furnace 7.1t2 are arranged in a two-ply (in the figure, it is double and small or 3Φ, hereinafter I) arrangement as shown in FIG. Alternatively, the furnace t112 may be installed as shown in FIG.
The smoke pipes 13 may be arranged intensively on the side of the gap 19, which is formed widely on the side of the external force. The bottom part 12 of the furnace cylinder 12
Since the a-side is made of a refractory material, the temperature of the combustion gas in the furnace tube 12 does not directly reach the bottom of the can body. Therefore, the accumulation of scale on the bottom of the can body will not cause overheating problems in the bottom.
