Description

Inverted combustion pressureless irrigation hot water boiler {a boiler}

The present invention relates to a reverse combustion pressureless irrigation type hot water boiler, and more particularly, by installing a separate combustion gas passage to circulate a high temperature combustion gas on the upper side of the combustion chamber to increase the internal volume of the combustion chamber to relatively increase the pressure inside the combustion chamber. This prevents incomplete combustion, noise, backfire, and rise of exhaust temperature, and also forms a plurality of water pipes in the flue gas passage and the bottom of the boiler, and maximizes the heat exchange area by filling the front cover with fruit. By maximizing the thermal efficiency, while the fruit circulates naturally, the circulation pump does not require a reverse combustion non-pressure irrigation type hot water boiler.

In general, a pressureless irrigation type hot water boiler is a water supply in the boiler maintained at no pressure, that is, the fruit is circulated up and down as the burner burns and is heated to a temperature below the boiling point, and the heated water circulates through the hot water pipe of the heat exchanger. By supplying hot water supply by heating, look at the configuration of the pressureless irrigation type hot water boiler in more detail with reference to Figure 1, the combustion gas generated in accordance with the combustion of the burner is inverted in the combustion chamber front of the boiler with the burner is formed Look at the inverted combustion hot water boiler exhausted to the side as an example.

Conventional inverse combustion hot water boiler, the furnace 21 is installed in the main body 12 of the boiler 10 to form the combustion chamber 20, and the water chamber 30 filled with fruit on the outside of the furnace 21. Bars are largely divided into one, one side of the furnace 21 is sealed as a front cover 22, the burner 15 is installed, the other side is sealed with a heat transfer plate 25, the water chamber 30 is a plurality of hot water pipes A heat exchanger 31 composed of 32 is provided, and an association 36 through which the combustion gas of the combustion chamber 20 is exhausted is formed so that the combustion gas is discharged to the outside through the exhaust pipe 38.

However, the inverted combustion hot water boiler 10 as described above is associated with the flame and hot combustion gas generated from the burner 15 after being inverted to the front cover 22 side in which the burner 15 is formed by the heat transfer plate 25. Bar 36 is discharged to the outside through the exhaust pipe 38, the pressure of the combustion chamber 20 is increased due to the flow of the combustion gas, causing problems such as incomplete combustion, noise, backfire phenomenon, rise in exhaust temperature, etc. In order to solve the problem as described above, in the case of the conventional inverse combustion hot water boiler 10, the size of the furnace 21 is increased by means of lowering the pressure in the combustion chamber 20, thereby increasing the diameter of the furnace 21. Accordingly, the boiler 10 is large and cannot be installed in a narrow space. Therefore, many restrictions are placed on the installation of the boiler 10. As the volume of the entire boiler 10 increases, the heat of the fruit to be heated in the water chamber 30 is increased. Capacity increases There is a problem in that a delay in supplying hot water and hot water.

In addition, the conventional inverted-fired boiler 10 forms the front cover 22 with insulation materials such as refractory materials, castables, ceramics, and the like to cover the combustion gas which is inverted, but covers the combustion gas of a high temperature. According to the use of the front cover 22 overheating not only causes heat loss, but also causes burner 15 breakage, and the desorption is inconvenient, so it is not easy to check, repair, and clean the inside of the combustion chamber 20. There is a burn hazard.

In addition, the heat exchange area between the cylindrical combustion chamber 20 and the fruit is small, and the heat efficiency decreases because the high temperature combustion gas does not stay inside the combustion chamber for a long time, and the cooled fruit around the heat exchanger 31 and the heating around the furnace 21 are heated. There is a problem that a separate circulation pump should be provided because the fruits do not collide smoothly due to collision.

An object of the present invention for solving the above problems is to form a separate combustion gas passage on the upper side of the combustion chamber to increase the volume of the combustion chamber to reduce the pressure without increasing the size of the boiler and to reduce the pressure, By increasing the residence time, it maximizes thermal efficiency, forms the fruit to circulate inside the front cover, recovers the heat released in the past, prevents burner failure and damage due to overheating of the front cover, and is easy to detach. It is easy to check, repair and clean the inside of the combustion chamber, there is no risk of burns, and the inverted combustion pressureless irrigation type hot water boiler is designed to make the fruit circulate naturally and to reduce the capacity of the fruit so that the hot water is supplied smoothly. .

The configuration of the reverse combustion pressureless irrigation type hot water boiler (hereinafter abbreviated as "boiler") according to the present invention for achieving the above object will be described in detail with reference to FIGS. 2 to 5.

Boiler 50 according to the present invention is formed in the main body 52 to form a combustion chamber 60, the furnace 61 and the upper portion of the furnace 61 to form a combustion gas passage 66 Of the heat exchanger 71 and the water chamber 70 installed in the upper portion of the communication tube 67, the furnace chamber 61 and the outside of the communication chamber 67 filled with fruit. The exhaust pipe 75 installed in the lower portion and the exhaust pipe 78 for discharging the combustion gas to the outside, the configuration of each part will be described in detail below.

Looking at the configuration of the combustion chamber 60 first, the combustion chamber 60 is formed by a cylindrical furnace barrel 61, the front side of the one side of the furnace barrel 61 is sealed with a front cover 62, the burner 55 is installed Fill the inside of the front cover 62, but the fruit is supplied to the inlet (63) formed in the lower portion of the front cover 62 is heated and discharged to the outlet (64) formed on the upper side of the front cover 62 The inlet 63 and the outlet 64 penetrate both sides of the boiler body 52, respectively, and are connected to the upper and lower sides of the water chamber 70, while the front cover 62 is installed on one side thereof. The other side of 61 is sealed by the heat transfer plate 65.

In addition, an upper portion of the combustion chamber 60 is provided with a rectangular communication 67 to form a combustion gas passage 66, and a plurality of water pipes 68 penetrating both sides of the communication 67 to form a communication The fruit filled in both sides of the chamber 70 is formed to circulate, and the upper end of the communication 67 is formed as a check opening for checking the inside of the combustion gas passage 66 so as to be openable and closed with a cover plate 69. do.

Looking at the configuration of the water chamber 70, the inside of the water chamber 70 is filled with fruit, the upper portion of the water chamber 70 is composed of a plurality of hot water pipes 72 on both sides of the communication 67 in the center The heat exchanger 71 is installed.

In addition, a flue gas 75 is formed in the lower portion of the water chamber 70, but the flue gas 75 is connected to the lower end of the furnace 61 on the front cover 62 side so that the combustion gas of the combustion chamber 60 is flue gas. Discharge to the outside through the exhaust pipe (78) and the exhaust pipe (78) connected to the exhaust pipe (75), the inside of the exhaust pipe (75) so that the fruit of the two outer chambers 70 of the exhaust pipe 75 can circulate. It is formed to penetrate through a plurality of water pipes 76, the exhaust pipe 75 including the water pipes 76 is formed so that one side is high and the other side is inclined low.

On the other hand, the water chamber 70 divides the water chamber 70 to both sides so that the fruit can naturally circulate in one direction, the thin partition 80 between the lower end of the furnace 61 and the upper end of the flue gas (75). By blocking the two sides of the water chamber (70), and on one side of the furnace (61) and the upper side of the exhaust pipe (75) by bending the circulating guide plate (85) for distinguishing the cooled fruit and the heated fruit integrally Although formed, the circulation guide plate 85 is formed to be somewhat spaced apart from the furnace (61) and flue gas (75).
