Description

{Prefabricated Boiler}

The present invention relates to a prefabricated boiler, and more particularly, to a prefabricated boiler which not only improves assembling workability, maintainability and maintainability at the time of construction of a boiler, but also can prevent heat loss from the hearth portion, So as to maximize heat efficiency by utilizing the waste heat of the communication.

Generally, briquette is less clean than other heat sources, but its economy is very high. It is used not only for farmhouses such as greenhouses, flower farms, poultry farms, but also for large houses and restaurants as indirect heating by boilers or heating.

However, the amount of heat is not very high as compared with other energy sources including fossil fuels such as liquid or gaseous fuels, and there are restrictions on the combustion conditions, which is inconvenient to use. That is, the number of times the briquette is usually changed once a day is suitable, but when the combustion condition is insufficient, the cycle is shortened and even the fire is likely to be turned off in the middle. This has a profound effect on yield and quality in the production of crops and flowers.

Nevertheless, coal is a long, low-cost resource considering the reserves of oil and gas. Therefore, unless other alternative energy sources are developed, the utilization of coal is inevitable in the fields where economic efficiency is important.

In recent years, as the cost of heating has risen due to the rise in international oil prices, a variety of boilers and stoves having briquettes as heat sources have been developed and supplied to farmhouses, greenhouses, and flower complexes.

Korean Patent Registration No. 10-0673620 (Announcement 2007.01.29) discloses a technique for heating water and hot water supply device of a briquet boiler as a prior art for achieving economical efficiency and efficiency of such heating. Such a boiler has a structure in which an oven is installed inside the body, a heating water tank is provided on the side and upper part of the oven, and a hot water pipe in the form of a coil is installed inside the body.

However, such a briquetting boiler does not have a means for preheating the heating water, so that it takes a long time to raise the temperature of the heating water, and the structure such as the provision of the heat insulating material in the body is complicated. In addition, most of the boilers are integrated with the heat source, so that the manufacturing process is complicated. In case of failure, both the heat source and the boiler must be replaced.

The heating water 130 is a component provided to heat the heating water by the heat generated from the stove part 110 (the side surface and the upper side of the outer body 119). The heating water tank 134 and the lid- A tank 138, and the like.

The heating water tank 134 is a component provided to heat the heating water to the upper side line of the outer body 119. The heating water tank 134 is inserted into the outer body 119 through the hollow S4 formed in the center, A first heating water feeding outlet 132 connected to the heating pipe end 10A and a first heating water feeding inlet 131 connected to the other heating pipe end 10B are provided on one side.

That is, the heating water tank 134 has a predetermined thickness and is formed in a tube shape so as to be fitted in contact with the outer body 119 in the same manner as the first hot water tank 124 described above. In the inner space, . At this time, the tube shape may be circular (see FIG. 6), elliptical or polygonal (see FIGS. 1 and 2).

Since the heating water tank 134 fitted in the outer body 119 and mounted on the upper end of the first hot water tank 124 covers the upper side area of the outer body 119, And serves as an insulating case for preventing the heat from being lost, and at the same time, heating water is heated by the heat radiated from this area.

The lid heating water tank 138 covering the upper part of the heating water tank 134 not only heats the heating water by the heat moving directly from the inside to the upper part of the stove part 110 but also to the upper part of the heating water tank 134 And also serves as an insulating case for shielding the emitted heat.

The heating water tank 134, the lid heating water tank 138 and the heating water preheating tank 150 to be described later are connected to each other by a connection pipe as shown in Fig. Specifically, the second heating and feeding outlet 136 and the second heating and feeding inlet 135 of the lid-type heating water tank 138 are connected to one side of the heating water preheating tank 150, which will be described later, . This is for the purpose of circulating a relatively short distance of heated hot water heated in the lid-type heating water tank 138 to the heating water preheating tank 150 without heat loss.

The other end 10B of the heating pipe and the first heating and feeding inlet 131 of the heating water tank 134 are connected to one side of the heating water preheating tank 150 by connection pipes and circulated.

This allows the high-temperature heating water supplied from the lid-type heating water tank 138 to be combined with the low-temperature heating water passing through the other end 10B of the heating pipe and the heating water preheating tank 150 so that the low- And the heating water thus preheated is circulated to the first heating and feeding inlet 131.

At this time, the tube shape may be circular, oval or polygonal.

Since the heating water preheating tank 150 installed in the communication pipe 140 surrounds the side surface of the communication pipe 140, the heating water preheating tank 150 serves as an insulating case to prevent heat from being lost to the outside And at the same time, the low-temperature heating water circulated from the other end 10B of the heating pipe is preheated by the heat radiated from the communication pipe 140.

At this time, the preheating by the communication pipe 140 is superimposed on the preheating by the high-temperature heating water supplied from the lid-type heating water tank 138 described above, so that the preheating efficiency of the heating water can be further increased. The heating water thus preheated is circulated to the first heating and feeding inlet 131.

The hot water circulation tank 160 is provided to enhance the preheating and circulation of the hot water and to further enhance the preheating of the hot water. The hot water circulating tank 160 is configured to surround the communication pipe 140, And one or two preheating pipes 162 and 164 are provided, respectively.

The partition wall portion 190 according to the present invention shown in Figure 5 is formed so as to meet with the lid 117 of the outer body 119 and to be guided toward the spacing space S2 while gas or heat generated in the combustion space S1 is moved upward And moves the downward movement path when moving downwardly. Thus, gas or heat is allowed to stay in the stove part 110 for a longer time. Therefore, the thermal efficiency of the stove part 110 can be increased by the formation of the partition part 190.

To this end, the separation space 190 including the first horizontal partition wall 192 and the second horizontal partition wall 194 is formed in the spacing space S2. The first horizontal partition wall 192 protrudes horizontally from the outer circumferential surface of the inner body 115 and is spaced along the vertical direction of the outer circumferential surface of the inner body 115. The second horizontal barrier ribs 194 protrude horizontally from the inner circumferential surface of the outer body 119 between the adjacent first horizontal barrier ribs 192 and are spaced along the vertical direction of the inner circumferential surface of the outer body 119.

This causes the gas or the heat generated in the combustion space S1 to move upwards toward the space S2 after being brought into contact with the lid 117 of the outer body 119 and moved downward to pass through the installation hole 118 ).

The gas or the heat generated in the combustion space S1 is supplied to the first hot water tank 124 that completely surrounds the stove part 110 while staying inside the stove part 110 for a long time while moving downward in the spacing space S2, Water and heating water in the heating water tank 134, the second hot water tank 128, and the lid-type heating water tank 138 are efficiently heated.

Next, the hot water generated in the first hot water tank 124 is introduced into the second hot water tank 128, heated again, and circulated to the first hot water inlet 121 through the hot water circulation tank 160.

Here, water conductance (not shown) may be provided between the hot water circulation tank 160 and the first hot water inlet 121 to provide hot water to the user. At this time, when the water level of the hot water circulation tank 160 is lowered by the use of the hot water, the water supply valve of the second auxiliary tank 170B is operated to open the water pipe to replenish the water.

On the other hand, hot water generated in the first hot water tank 124 and the second hot water tank 128 while the hot water is not used is continuously circulated through the hot water circulation tank 160, Since the heat is continuously supplied to the heating water preheating tank 150 through the heat pipes 162 and 164, the low temperature heating water passing through the other end 10B of the heating pipe can be effectively preheated.

The hot water heated in the heating water tank 134 is heated by the heating water circulation pump 182 under the control of the temperature switch 180 through the first heating water feeding outlet 132 to the heating pipe 10, . At this time, as the high-temperature heating water sent out from the first heating and drinking water outlet 132 generates heat loss while passing through the heating pipe 10 arranged in a long area, the low-temperature heating water Which is introduced into the heating water preheating tank 150.

The hot water heated in the lid heating water tank 138 flows into the heating water preheating tank 150 through the second heating water feeding outlet 136 and flows out to the other end of the heating water preheating tank 150, 135 to the lid-type heating water tank 138 again. This is for continuously supplying hot water of a high temperature for preheating low temperature hot water passing through the other end 10B of the heating pipe.

Next, the low-temperature heating water flowing into the heating water preheating tank 150 from the other end 10B of the heating pipe receives heat through the first and second preheating pipes 162 and 164, and is supplied to the lid- 138 and receives heat from the hot water heated by the heating water preheating tank 150 and also receives heat from the communication tube 140 wrapped by the heating water preheating tank 150,

The heating water in the heating water preheating tank 150 having been preheated in the three stages flows out through one side and circulates to the first heating feeding inlet 131. The heating water in the heating water tank 134 flows from the outside body 119 It can be easily heated by heating to high temperature heating water.

On the other hand, when the water level of the heating water contained in the heating water preheating tank 150 is lowered, the water supply valve of the first auxiliary tank 170A is operated to open the water pipe to replenish the water.
