Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a furnace smoke tube boiler, which consists of 8 parts j-, , F, and the heat transfer of the furnace tube or smoke tube group (the part is fJ, and the -L part is only at the same time). Multiple connections between the trunk and the L part trunk 9
This invention relates to a fire tube boiler which is small in size and has a horizontal periphery, and which significantly reduces the amount of evaporated phosphorus.

Looking back at the development process of the furnace and smoke tube boiler, we can see that it has been greatly influenced by fuel conditions1, but improvements have always been made to create small, high-performance boilers.17. That was the case.

In particular, regarding miniaturization,
It has been known for a long time that the scope of boiler operators will be greatly expanded and this will have the advantage of greatly contributing to economic development.

However, in order to limit the K = J method, it is necessary to store the furnace tube and smoke tube in one limited location, and it is not possible to simply store the heat transfer direction of the furnace tube, smoke tube, etc. However, it is not a complete thing on its own, but its surroundings (・
In order to keep the volume of the air chamber sufficient (Mn), it is necessary Since the direction of heat transfer stored in the tank is determined, the steam 11 produced
(However, OJ+' had the drawback of always decreasing.

It is a typical lever-type fire tube boiler.
, the equivalent evaporation amount (1 village, abbreviated as E) is 100 to 200
Kl//hr was the limit.

g is an IJ as a conventional furnace smoke tube boiler designed to eliminate the disadvantages mentioned in -1-, either a standing dome (16) is installed as shown in Fig. 1, or as shown in Fig. 2. It was customary to provide a separate steam/water separator (17) and connect it with 111-piping. In this way, F',,B.

The power can be increased to l1550~60 oKg/hr; even with this, the evaporation area that governs the steam/water separation performance cannot be sufficiently accommodated, so the Otani capacity of the boiler is reduced to 1lZl:power.
Lee (I didn't have it.

Misfire 1 is a small F2.
.

However, the large capacity at 1:+aoKg/hr made it possible to achieve this.

Next, the present invention will be explained with reference to the drawings. FIG. 3 shows a cross-sectional view of one embodiment of the present invention, in which (1) is the first layer;
(2) is a -1 layer with a furnace cylinder (9) only in the lower shell (1)
and a smoke pipe ([5) are stored, and the upper fl+ is equipped with a front smoke chamber (, le), a smoke extraction chamber (4), and a smoke pipe (8), and the upper part of the body has a surrounding area. It is equipped with a shielding flat plate (11) that is open at various times, and a plurality of connecting pipes (
By connecting in 5), a fire tube boiler for non-exploding IJI is constructed.

The combustion gas is stored in the furnace tube f! 41, smoking pipe (
6) and is discharged from the front smoke chamber (3).
) The combustion gas does not pass through the inside.

There are xylem (12) around these areas, but the water surface (
Ii) is advantageously arranged in a plurality of connecting pipes (5) connecting the upper part (1) and the second part (2).

Normal water level (12) does not support water under normal loads, but when the load becomes large, it can be thrown into the connecting pipe (12). L
It becomes easier.

Furthermore, the central part in the part (2) [-1 part (1), (
A shielding plate (11) is provided in the water 317 within a range corresponding to the outlet 1 of the connecting pipe (5) connecting the people to the people, and the area around the shielding plate (11) is ) to serve as a steam passage.

That is, the two-phase fluid containing <'ly air is ejected from the connecting pipe (12), but this j! The steam is distributed to the ants by hitting the plate (11) one by one, and the steam passes through the passage (15).
It is released through 11.
