In the following, with reference to the accompanying drawings, a preferred embodiment of a vertical firewood boiler according to the present invention will be described in detail.

1 is a perspective view of a vertical firewood boiler showing one embodiment according to the present invention, FIG. 2 is a cross-sectional view showing a vertical firewood boiler shown in FIG. 1, and FIG. 3 is a vertical firewood boiler shown in FIG. 1. 4 is a plan view illustrating a firewood boiler, and FIG. 4 is a side view of the vertical firewood boiler illustrated in FIG. 1, and FIG. 5 is a front view of the vertical firewood boiler illustrated in FIG. 1.

As illustrated in FIGS. 1 and 2, the vertical firewood boiler 100 includes a combustion chamber 110 in which firewood burns, and surrounds the combustion chamber 110 so that heating water is filled outside the combustion chamber 110. A housing 140 and a hot water pipe 160 which surrounds the outer side of the combustion chamber 110 and extends outwardly of the housing 140 are divided.

A crater 131 is formed at a side of the combustion chamber 110 that is vertically positioned, and inserts firewood into the combustion chamber 110 through the crater 131. The crater 131 opens and closes the opening and closing door 135 to open and close the crater 131. In addition, a plurality of couplers 151, 152, 153, 154, 155, and 156 are formed on the outer surface of the housing 140 to provide heating water pipes 171, 173, water supply pipes 161, 163, and temperature gauges ( 181 and a safety valve 183 is mounted.

Hereinafter, the vertical firewood boiler configured as described above will be described in more detail.

As shown in FIG. 1 and FIG. 2, the combustion chamber 110 is located inside the housing 140.

The combustion chamber 110 is a vertical type, has a cylindrical structure with a top and a bottom closed, the chimney 120 is in communication with the top of the combustion chamber 110, the horizontal charging cylinder 130 of the combustion chamber 110 In communication with the bottom side. In addition, a plurality of heating tubes 111 are positioned at upper ends of the combustion chamber 110, and both ends of the heating tubes 111 are exposed to the outside of the combustion chamber 110 through the outer wall of the combustion chamber 110. As such, both ends of the heating tube 111 are exposed to the outer wall of the combustion chamber 110, so that the heating water 1 filled in the outside of the combustion chamber 110 flows along the heating tube 111. As will be described later, the heating water 1 flowing along the heating tube 111 receives the heat generated in the combustion chamber 110 directly, causing rapid convection of the heating water 1.

On the other hand, the horizontal charging container 130 has a rectangular cylinder structure, the entrance of the charging container 130 is the crater 131, the opening and closing door 135 is hingedly coupled to the crater 131 is installed in a swing. Therefore, by opening and closing the door 135 and charging the firewood into the combustion chamber 110 through the charging container 130, the firewood burns in the charging container 130 and the combustion chamber 110. On the other hand, the opening and closing door 135 has a plurality of through-holes (135h) is formed radially, corresponding to the through-holes (135h) formed in the opening and closing doors 135, the rotary air control plate 137 is rotatably mounted, the rotary air conditioning plate ( The through hole 137h formed in the 137 corresponds to the through hole 135h of the open / close door 135.

Therefore, as the air control plate 137 rotates, the through-hole 135h of the open / close door 135 is opened or the through-hole 135h of the open / close door 135 is closed. As such, while the through hole 135h of the opening and closing door 135 is opened or closed, the amount of combustion air flowing into the combustion chamber 110 is adjusted. In general, the internal pressure of the combustion chamber 110 is relatively lower than atmospheric pressure. The reason is that since the temperature inside the combustion chamber 110 is higher than the temperature outside, the air density in the combustion chamber 110 is low and the pressure is low. Therefore, the combustion air naturally flows into the combustion chamber 110 through the through hole 137h of the air control plate 137 and the through hole 135h of the opening / closing door 135 by the pressure difference. In addition, as shown in Figure 2, the reinforcing rod 133 is fixed to the outer surface of the charging container 130, to prevent the charging container 130 is thermally deformed.

On the other hand, the housing 140 surrounds the outside of the vertical combustion chamber 110 and the horizontal charging container 130, only the crater 131 of the charging container 130 is exposed to the outside of the housing 140, the housing ( The heating water 1 is filled inside the 140.

More specifically, the housing 140 is a shape similar to that of the combustion chamber 110 and the charging cylinder 130 which are integrally formed, and the vertical cylinder 141 of the housing 140 corresponding to the combustion chamber 110 has a cylinder in which the upper and lower ends are closed. The structure, the chimney 120 is located through the upper end of the vertical cylinder 141, the combustion chamber 110 is located in the vertical cylinder 141. And the horizontal cylinder 143 is communicated to the lower end side of the vertical cylinder 141, the charging cylinder 130 is located inside the horizontal cylinder 143. In addition, the inlet of the horizontal container 143 and the inlet of the charging container 130 are interconnected to form the crater 131. In this way, the heating water 1 is filled in the sealed space formed by the housing 140 and the combustion chamber 110 and the charging container 130 located therein. The plurality of pedestals 139 are pinched between the combustion chamber 110 and the inner surface of the vertical cylinder 141 of the housing 140, and between the charging cylinder 130 and the inner surface of the horizontal cylinder 143 of the housing 140. The heating water 1 is configured to flow.

In addition, a plurality of couplers 151 to 156 are formed at the upper and side portions of the vertical cylinder 141 and the side of the horizontal cylinder 143 of the housing 140. Coupler (151 to 156) is a male screw structure in which the hollow is formed, it is welded fixed in communication with the interior of the housing (140). Although the coupler 151 to 156 will be described in detail later, the hot water supply pipes 161 and 163, the heating water pipes 171 and 173, the safety valve 183, the temperature gauge 181, and the like are mounted.

On the other hand, as shown in Figure 2, the hot water supply pipe 160 is positioned wrapped in contact with the outer surface of the combustion chamber 110 in the form of a coil. Both ends of the hot water supply pipe 160 are connected to the first and second hot water pipe couplers 151 and 152 respectively formed in the housing 140. The hot water supply water supply pipe 161 is connected to the first hot water pipe coupler 151, and the hot water supply drain pipe 163 is connected to the second hot water pipe coupler 152. In general, the hot water supply pipe 161 is connected to the water pipe, the hot water supply pipe 163 is connected to the piping of the sink for the bathroom and kitchen.

The housing 140 has first and second heating water pipe couplers 153 and 154 formed therein. A heating water supply pipe 171 is connected to the first heating water pipe coupler 153 to supply the heating water 1 into the housing 140, and the heating water 1 heated inside the housing 140 is formed. 2 is discharged through the heating water drain pipe 173 through the heating water pipe coupler 154. Here, the heating water supply pipe 171 and the heating water drain pipe 173 are connected to the heating hose of the building to dissipate the heat of the heating water 1 to heat it.

In addition, the temperature gauge 181 is fastened to the coupler 155 formed at the top of the housing 140 to measure the temperature of the heating water 1, and the other coupler 156 is equipped with a safety valve 183 and the housing 140. To control the internal pressure.

Hereinafter, a relationship of producing the heating water 1 or the hot water supply water 2 using the firewood boiler 100 configured as described above will be described.

The user opens and closes the door 135 and puts firewood through the crater 131 to catch fire and burn the firewood. When the firewood burns, the user closes the opening / closing door 135 and rotates the air control plate 137 to open the through-hole 135h of the opening / closing door 135 so that the burning wood can burn well.

As the firewood burns in the combustion chamber 110 and the charging container 130 as described above, the heat is generated, and the heat is transferred to the charging container 130 and the combustion chamber 110 to fill the inside of the housing 140. Heat 1). On the other hand, the combustion gas heated in the combustion chamber 110 and the charging chamber 130 is lowered in density to rise to the upper side along the combustion chamber 110, at this time by rotating in a whirlwind form by the density difference inside the combustion chamber 110 To rise. As the combustion gas inside the combustion chamber 110 rotates and rises, the combustion gas is naturally discharged without forcibly discharging the combustion gas, and the combustion air naturally flows into the combustion chamber 110 through the through hole 135h of the opening / closing door 135. The combustion gas heated in the combustion chamber 110 as described above is transferred through the chimney 120 after transferring heat to the plurality of heating tubes 111 located at the top of the combustion chamber 110 while rising. The flame generated in the combustion chamber 110 also directly contacts the heating tube 111 to transfer the heat of the flame to the heating tube 111.

The heat transferred to the heating tube 111 as described above heats the heating water 1 located inside the heating tube 111. In order to further improve the heat recovery rate, the longer the length of the heating tube 111 is, the better. Therefore, it is preferable that the heating tube 111 having a length longer than the inner diameter of the charging container 130 is disposed in an obliquely inclined state inside the combustion chamber 110. As the heating tube 111 is positioned obliquely as described above, convection of the heating water 1 filled in the housing 140 is also effectively generated to uniformize the heat distribution of the heating water 1.

In this way, the heating water 1 heated by burning the firewood is drained through the heating water drain pipe 173 to heat the room.

On the other hand, when the user needs the hot water supply water 2, the hot water supply water 2 is supplied to the hot water supply water supply pipe 161. Then, the hot water supply water 2 flows along the hot water supply pipe 160 and is drained through the hot water supply drain pipe 163. The hot water supply water 2 flows along the hot water supply pipe 160 to the heat of the combustion chamber 110. It takes away and becomes high temperature.

That is, since the hot water supply pipe 160 is in contact with the outer surface of the combustion chamber 110 and a small amount of the hot water supply water flows, it is possible to quickly absorb the heat transferred from the combustion chamber 110. Rapidly heated hot water supply water 2 is supplied to the bathroom or kitchen through the hot water supply drain pipe 163.

On the other hand, in order to supply the hot water supply water 2 and the heating water 1 in this way, the hot water supply water supply pipe 161 or the hot water supply water drain pipe 163, and the heating water supply pipe 171 or the heating water drain pipe 173, Is installed to control the flow rate. Such a valve is a conventional technique and is a peripheral device of a vertical fired boiler. Therefore, detailed description of the valve is omitted.

The heating water 1 is heated inside the housing 140 to generate steam. When the steam pressure is higher than or equal to the proper pressure, the safety valve 183 is discharged to maintain a safe firewood boiler 100. In addition, the user measures the temperature of the heating water 1 through the temperature gauge 181 mounted on the housing 140, and adjusts the temperature of the heating water 1 by charging the fuel or adjusting the combustion state.

Different types of boilers, such as oil boilers and regenerative boilers, can be connected to the coal fired boiler described above. The relationship between the coal fired boiler and other boilers is described below without drawing.

In order to connect other boilers to the firewood boiler, install a coupler in the housing.

When the oil boiler is to be connected, the heating water supply pipe 171 and the heating water drain pipe 173 respectively connected to the first and second heating water pipe couplers 153 and 154 are connected to the oil boiler. Then, the heating water 1 is heated in either boiler or both boilers while circulating from the coal fired boiler 100 to the oil boiler or the oil boiler to the coal fired boiler in the circulation order.

When installing the regenerative boiler, the electric heater of the regenerative boiler is fastened and fixed to the coupler such that the electric heater is positioned inside the housing 140. When a voltage is applied to the electric heater configured as described above, resistance heat is generated in the electric heater. Heating water is heated as this resistance heat.

Meanwhile, among the components of the firewood boiler 100, the components contacting the heating water 1 and the hot water supply 2 may be corroded, and thus, the components contacting the heating water 1 and the hot water supply 2 to prevent this. The element is made of stainless steel (SUS 304). Specifically, the chimney 120, the combustion chamber 110, the charging cylinder 130, the vertical cylinder 141 and the horizontal cylinder 143 of the housing 140, the pedestal 139, the heating tube 111 are made of stainless steel (SUS). 304 is made of, and the hot water supply pipe 160 is located in the heating water 1 and is preferably a copper pipe because it must be rapidly heated. Thus, by using a component in contact with water as a stainless steel or copper tube excellent in corrosion resistance, it is possible to prevent the iron oxide due to corrosion blocking the pipe. And the opening and closing door 135 and the air conditioning plate 137 not in contact with water is made of cast steel.

On the other hand, in addition to the fuel inside the charging cylinder 130 and the combustion chamber 110 may be supplied by burning waste oil. In this case, through-holes are formed in the opening / closing door 135, the nozzle is inserted into the through-holes, and then the waste oil is injected through the nozzles to combust.

In the above-described firewood boiler, the thermal efficiency varies greatly depending on the size. The following describes the size of the wood fired boiler that can achieve the best thermal efficiency of the wood fired boiler configured as described above.

In order to obtain good thermal efficiency, in the case of a firewood boiler having a low capacity of 400 l, the combustion chamber 110 has a height of 830 ± 5 mm in a diameter of 350 ± 5 mm, the chimney 120 770 ± 5 mm in a diameter of 100 ± 5 mm It has a height of, the charging container 130 is formed of a duct structure having a width of 350 ± 5mm and a length of 450 ± 5mm and a depth of 780 ± 5mm.

In the case of a firewood boiler having a low capacity of 1,500 l, in order to obtain good thermal efficiency, the combustion chamber 110 has a height of 1,220 ± 5 mm at a diameter of 600 ± 5 mm, and the chimney 120 has a diameter of 250 ± 5 mm at 780 ± It has a height of 5mm, the charging container 130 is formed of a duct structure having a width of 600 ± 5mm, a length of 650 ± 5mm and a depth of 1,200 ± 5mm.

On the other hand, a plurality of couplers are formed in the housing 140 shown in the drawing. Among the couplers which are not used among these couplers, the coupler is closed by screwing a socket in which a female thread part is formed.

As described above in detail, the vertical firewood boiler of the present invention has the advantage that the firewood boiler can be installed even in a narrow installation area as the combustion chamber is vertically positioned. In addition, the components are simple, and hot water and heating water can be produced, thus simplifying production. In addition, by producing two types of hot water, there is an advantage that the use is wide and provides convenience in use.

In addition, the vertical firewood boiler of the present invention has the advantage of having a uniform temperature distribution by the convection of the heating water by the heating tube, and has a vertical combustion chamber so that the combustion gas is evacuated by the pressure difference in the form of a whirlpool. Therefore, as the supply of exhaust and combustion air is made naturally, there is an advantage that a facility for forcibly exhausting gas or supplying combustion air is not required. In the case of the firewood boiler which previously defined the dimensions of the combustion chamber, the charging container and the communication, the firewood of the charging container and / or the combustion chamber burns well without the exhaust fan, and combustion is carried out for about 12 to 14 hours by one firewood input. Therefore, there is an effect that can maximize the thermal efficiency.

In addition, the vertical firewood boiler of the present invention can use waste oil in addition to firewood as a firewood, and can also be used in conjunction with other types of boilers, such as oil boilers and regenerative boilers to compensate for the disadvantages of firewood boilers.

The technical idea of the vertical firewood boiler of the present invention has been described above with the accompanying drawings, but this is only illustrative of the best embodiment of the present invention and is not intended to limit the present invention.
