Abstract

A water pipe type steam and hot-water boiler is provided to rapidly make and supply hot-water and steam by moving and exhausting a combustion heat source from a lower side to an upper side in zigzags and transferring water from a lower side to an upper side to have a maximum thermal conductive area. A water pipe type steam and hot-water boiler(1) includes an outer casing(2). A combustion chamber(3) is formed inside the outer casing. A first water chamber(4) embraces the combustion chamber. Heat exchange pipes(5,7) connect the outer casing and a second water chamber(6), and connect the second water chamber and a third water chamber(8) for transferring a heat source generated in the combustion chamber to water. First and second heat passage chambers(9,10) are communicated with the combustion chamber through more than one communicating pipe(3a) for exhausting the heat source after transferring heat through the heat exchange pipes, and the second and third water chambers. The heat transfer pipes are formed inside the second heat passage chamber for water inside the third water chamber to receive waste heat more efficiently. The water and steam passed through the third water chamber are discharged through an exhaust pipe.

The present invention relates to a water pipe steam and hot water boiler, and more particularly, the combustion heat source is moved from the bottom to the top, and exhausted, and the water is rapidly heated while passing through the combustion chamber and the hot air chamber installed step by step. It is to provide a water pipe-type steam and hot water boiler that can increase the heat recovery rate by allowing the heat source having more efficient heat transfer.

Conventional steam and hot water boilers heat water by receiving heat sources generated from combustion chambers, and generate hot water and steam, but the heat transfer area is small and the heat of combustion stays in the boiler, so the heat of combustion heat is efficient and heat transfer. There were a number of problems such as waste heat recovery is not made smoothly.

In the present invention to solve the problems of the existing steam and hot water boiler as described above to provide a steam and hot water boiler of a new configuration,

In particular, the present invention is a combustion heat source is gradually moved to the zigzag phase from the inner bottom of the boiler to the top, and exhausted, the water is introduced into the vicinity of the combustion chamber and the heat collection chamber where the combustion heat source moves to the upper portion to maximize the heat transfer area The invention provides a water pipe steam and hot water boiler which is very useful in terms of energy savings by allowing the hot water and steam to be produced and the heat of the exhaust gas exhausted to be recovered and recovered as much as possible. The present invention has been completed.

Figure 1 is a cross-sectional view showing a water pipe steam and hot water boiler (1) provided by the present invention, Figure 2 is a side cross-sectional view, etc., together with these drawings will be described the present invention in detail.

Water pipe steam and hot water boiler (1) of the present invention forms a combustion chamber (3) inside the outer casing (2) constituting the boiler, the primary water chamber (4) in the form of surrounding the outside of the combustion chamber (3) It can be formed by the outer casing (2).

The upper part of the outer casing (2) is connected to several heat exchange pipes (5) and the upper part of the heat exchange pipe (5) to communicate with the secondary water chamber (6).

In addition, a plurality of heat exchange pipes 7 are connected to the upper part of the secondary water chamber 6, and the upper part thereof is connected to the tertiary water chamber 8 so that the upper part of the secondary water chamber 6 may be connected to the third water chamber 8. Allow the heat source generated in 3) to be heated in the water.

The heat source generated in the combustion chamber 3 passes through the heat exchange pipes 5 and 7 and the secondary and third water chambers 6 and 8, and passes through the at least one communication tube 3a to be exhausted after the heat transfer. Through the first hot air via chamber 9 and the second hot via oil chamber 10 are formed to communicate with the combustion chamber 3, respectively.

That is, the primary hot oil passage 9 is in communication with the upper part of the combustion chamber (3) and the communication tube (3a) of one or more (in the case of one case shown) and the heat exchange pipe (5) and the secondary water chamber ( 6) and the secondary hot air passage chamber 10 is formed inside the tertiary water chamber 8 so that at least one of the primary hot air passage chamber 9 and the center are mutually formed (in this case, 1). Individual case) to communicate with the communication pipe (3a), and through the secondary hot air via room 10, the waste gas heat transfer is to be discharged through the flue (11).

In the secondary hot oil passage 10, several heat transfer pipes 12 penetrate into the secondary hot oil passage 10 so that water introduced into the tertiary water chamber 8 can be more efficiently transferred to the waste heat. Install the pipe.

In addition, the warmed water, that is, hot water and steam, may be discharged through the discharge pipe 13 while passing through the third water chamber 8.

In the figure, 14 is a safety valve mounting portion, 14a is a pressure gauge mounting portion, 15 is a burner installation hole is installed, 16 is a sight glass, 17 is a water injection pipe, 18 is a drain pipe.

The present invention can be configured as described above when the burner (not shown) is installed on the burner mounting hole 15, the heat source generated in the combustion chamber (3) is moved to the top zigzag through the communication pipe (3a) to the flue By heating the heat source to the water introduced through the water inlet pipe 17 until it is exhausted to (11), the hot water and steam can be supplied by heating the water quickly and efficiently, and its action will be described in more detail below. same.

The heat source generated in the combustion chamber 3 conducts heat to the water in the primary water chamber 4 which encloses it, and moves to the primary hot oil passage chamber 9 through the communication tube 3a to exchange heat exchange pipes 5. And the water is continuously heated while zigzag between the secondary water chamber 6 and the heat exchange pipe 7 again, and the secondary heat communicates through the primary hot air passage chamber 9 and the communication pipe 3a. It moves to the hot oil passage 10 and warms the water on the third water chamber 8 which also surrounds it to supply hot water and steam, and communicates with the third water chamber 8 and the second hot oil passage chamber. (10) The waste heat in the waste gas exhausted while passing through the water on the heat transfer pipe 12 piped into the inside is actively electrothermally recovered to minimize waste of energy.

As described above, the present invention moves and exhausts the combustion heat source from the lower side to the upper side in a zigzag manner, thereby allowing the water to be warmed several times with a large heat transfer area so that hot water and steam can be supplied quickly and efficiently.

As described in detail above, the water pipe-type steam and hot water boiler (1) provided by the heat source of the burner generated in the combustion chamber (3) to heat the water to supply hot water and steam, but the combustion heat source In order to move and exhaust the zigzag from the lower part to the upper part, the water is transferred from the lower part to the upper part in several water chambers enclosing the inner and outer parts of the combustion heat source in the upper part to have the maximum heat transfer area. Hot water and steam can be made and supplied quickly, and the waste heat of the exhaust gas can be transferred to the water as much as possible, which is a very useful invention in terms of energy saving.
