The present invention relates to a domestic heating boiler, and in particular, the combustion state of the boiler in which the combustion exhaust is formed in a long wave form is good so that the heat utilization efficiency is high.

Conventional heating boilers have a large amount of heat loss because the combustion exhaust passage is linearly formed without many bends, and the combustion exhaust velocity is fast.

Therefore, in recent years, in order to prevent heat loss, the combustion exhaust passage has been formed with a long waveform to extend the residence time of the combustion heat and to increase the absorption area (Korean Utility Model Publication No. 86-3841). Form the corrugated space inside the tub, and install a separate inner heating tub in multiple stages in which the shape of the space is reduced in the space of the wide part, so that it can be passed through or separated from the outer tub.

Since the combustion exhaust passage of the boiler is long in wave form, the combustion flame goes up to some extent and the flame is extinguished due to lack of combustion air and is exhausted to the unburned state.

Therefore, there is a lot of fuel loss and lead loss due to the poor combustion state, there is a serious problem of soot, the formation of the corrugated space in the heating tube and the installation of the inside of the hot tub is very difficult to manufacture, it is inconvenient to manufacture, cleaning the combustion exhaust passage Difficult to manage, there was a problem inconvenient.

In the present invention, in order to solve the conventional problems as described above, the combustion air is supplied to the narrow portion of the long-wave-shaped combustion exhaust passage, and the narrow portion is disassembled and assembled so that the production is easy and convenient to use and manage. .

This configuration will be described in detail with reference to the accompanying drawings.

In forming a boiler in which a long corrugated combustion exhaust passage is formed therein, the internal heating cylinder 1b is fitted inside the external heating cylinder 1a so as to be passed through the water pipe 2 so that the internal and external heating cylinder 1a, A plurality of small boilers 1 having a plurality of exhaust passages 3, which are similar to the shape of the abacus eggs, are stacked between (1b), with a sufficient ventilation space 6 therebetween, and the exhaust passages communicating with each other. ) Large and small communication pipes 4 and 5 are formed on the outer circumferential surface of the upper and lower ends thereof so that the large communication single pipe 4 is fitted outside the small communication pipe 5. The outer circumferential edges of the small boilers 1 stacked in this way are connected to each other by the outer water pipe 7 so that the laminated state is fixed.

In the drawings, reference numeral 8 denotes an outer cylinder, 9 burner, 10 air supply port, and 11 communication.

When explaining the working effect of the present design the combustion heat of the burner is exhausted to the communication (11) via the exhaust passage (3) repeatedly communicated in the shape of the abacus egg, the exhaust passage (3) is a long communication in the waveform This results in longer heat retention times and a larger heating area.

Ventilation holes 4 'and 5' are provided in the small and medium communication end pipes 4 and 5 provided in the narrow portion of the exhaust passage 3 so as to be connected to each other. The air necessary for combustion is supplied from the space 6 to the vent holes 4 'and 5', and the combustion flame does not turn off but is sufficiently burned while being burned up to prevent soot, resulting in more calorific value than before. While passing through (3), it is absorbed by the inner and outer heating cylinders 1a and 1b to increase the efficiency of heat use, and the small boiler 1 is inactivated to form the small and medium-sized single tube 4 and 5 so that the outer periphery The edge is connected to the outer water pipe (7) is easy to disassemble and assemble, easy to manufacture and easy to clean management.
