[First Embodiment]

2 is a schematic view showing the fluid flow of the oil boiler and the firewood boiler according to the first embodiment of the present invention.

As shown in FIG. 2, the first and second branch pipes 211 and 212 are branched to the circulation pipe 40 connected to the heating water inlet 201 of the oil boiler 200, respectively, and the first branch pipe ( The first valve 221 is installed at 211. The second branch pipe 212 is provided with a second valve 222. In addition, a third valve 223 is installed in the circulation pipe 40 between the first branch pipe 211 and the second branch pipe 212.

In addition, the first and second branch pipes 211 and 212 are respectively connected to both ends of one of the two flow paths (not shown in the drawing) of the firewood boiler 100. Therefore, the heating water 1 introduced through the circulation pipe 40 is introduced into the firewood boiler 100 through the first branch pipe 211, and the heating water 1 flows along the flow path of the firewood boiler 100. While heated while being introduced into the heating water inlet 201 of the oil boiler 200 through the second branch pipe (212).

In order to replenish the heating water from the make-up water tank 190 to the firewood boiler 100, the make-up water tank 190 should be installed above the firewood boiler and have a higher elevation than the circulation pipe 40. The replenishment tank 190 extends the branch pipe 193 branched from the hot water induction pipe 213 to inject the rapidly heated hot water into the replenishment tank 190.

The reason for injecting the hot water into the replenishment water tank 190 is that the boiler is used for a long time in winter, and thus the replenishment amount of the replenishment water increases due to the large amount of evaporation of the heating water 1. On the other hand, as described in the prior art, when cold cold water is injected into the replenishment water tank 190, the temperature of the heating water drops sharply and the thermal efficiency of the boiler is reduced. Therefore, the hot water feeder 2 heated in the firewood boiler 100 is injected into the replenishment water tank 190 to prevent a decrease in temperature of the heating water. A discharge port 195 is formed in the replenishment water tank 190 such that the water is naturally drained when the level of the replenishment water becomes greater than or equal to the discharge port 195.

Discharge. In particular, since the steam discharge pipe 197 discharges steam generated by overheating when the heating water is overheated due to a power failure or the circulating pump is not broken, there is an effect of preventing the explosion of the boiler due to the expansion of the heating water.

In addition, the circulation pump 207 is installed at two points of the heating water circulation pipe 40 for smooth circulation of the heating water 1 circulating along the heating water circulation pipe 40. The point where the circulation pump 207 is installed is preferably installed at the front and rear of the oil boiler 200 in the circulation direction of the heating water 1.

If desired, the third valve 223 installed in the circulation pipe 40 is locked, and the first and second valves 221 and 222 are opened. Then, the heating water 1 introduced through the circulating pipe 40 flows to the firewood boiler 100 along the first branch pipe 211 and is heated, and again, the oil boiler 200 along the second branch pipe 212. ) Is reheated in the oil boiler (200). And it is drained through the heating water outlet 202 of the oil boiler (200).

On the other hand, when only the oil boiler 200 is operated, the third valve 223 is opened, and the first and second valves 221 and 222 are closed to provide the heating water 1 introduced from the circulation pipe 40. Flow into the oil boiler 200 is controlled to be heated.
