As shown in FIG. 1 and FIG. 2, the regenerative composite boiler 100 is largely equipped with a vertical combustion chamber 110 in which a fire and a burner 190 located therein, and heating water outside the combustion chamber 110. A housing 140 surrounding the combustion chamber 110 to be filled, a chimney 120 communicating with the combustion chamber 110 and extending out of the housing 140 and having a cleaning chamber 121 formed therebetween, and the housing 140. A fuel tank 192 and a blower 194 for supplying oil and combustion air to the electric heaters 198 positioned in the housing 140 and the burner 190 located in the combustion chamber 110 through the through hole. And, the outer surface of the electric heater 198 and the outside of the combustion chamber 110, both ends are divided into a hot water supply pipe 160 extending to the outside of the housing 140.

Hereinafter, a vertical hybrid 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 in the middle of the inside of the combustion chamber 110, and both ends of the heating tube 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 is directly received the heat generated in the combustion chamber 110, the rapid heating and flow of the heating water (1) filled inside the housing 140 Cause convection;

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 first opening door 135 is hingedly coupled to the crater 131 is installed in a swinging manner. . Therefore, by opening the first opening and closing door 135 and charging the firewood into the combustion chamber 110 through the charging container 130, the firewood is burned in the charging container 130 and the combustion chamber 110. Meanwhile, a plurality of through holes 135h are radially formed in the first opening and closing door 135, and the rotary air regulating plate 137 is rotatably mounted to correspond to the through holes 135h formed in the first opening and closing door 135. The through hole 137h formed in the rotary air control plate 137 corresponds to the through hole 135h of the first opening / closing door 135.

Therefore, as the air control plate 137 rotates, the through hole 135h of the first open / close door 135 is opened or the through hole 135h of the first open / close door 135 is closed. As such, while the through hole 135h of the first 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 first opening and 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, 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.

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.

On the other hand, the chimney 120 communicated with the upper end of the combustion chamber 110 extends upwardly and passes through the housing 140 to the outside, the cleaning chamber 121 is formed in the middle of the length of the chimney 120. The cleaning chamber 121 is positioned in a horizontally bent structure with respect to the chimney 120 extending vertically upward from the combustion chamber 110, the chimney 120 is extended to the cleaning chamber 121 to the vertical tube of the housing 140 It penetrates 141 and is exposed to the outside.

Therefore, the combustion gas flowing upward from the combustion chamber 110 along the chimney 120 flows horizontally along the cleaning chamber 121 and then flows upward again along the chimney 120 to be exhausted. As illustrated in FIG. 2, the chimney 120 positioned in front and rear of the cleaning chamber 121 may be bent and formed a plurality of times. The structure of the chimney 120 is designed on the premise of smooth discharge of the combustion gas. On the other hand, one or more heat storage plates 123 are attached to the cleaning chamber 121 to extract heat from the flowing combustion gas to heat the heating water 1. This cleaning chamber 121 can be seen as part of the chimney 120 structurally.

On the other hand, the vertical barrel 141 of the housing 140 is mounted with a second opening and closing door 125 to open and close the entrance of the cleaning chamber 121 exposed to the outside of the vertical cylinder 141.

A plurality of couplers 151 to 157 are formed at the upper and side portions of the vertical cylinder 141 and the side of the horizontal cylinder 143 configured as described above. Coupler (151 to 157) is a male screw structure in which the hollow is formed, is welded and fixed in communication with the interior of the housing (140). Such couplers 151 to 157 will be described in detail later, and the couplers 151 to 157 are provided with hot water supply pipes 161 and 163, heating water pipes 171 and 173, safety valves 183, and temperature gauges. 181 and electric heater 198 are mounted. Here, the couplers 151 to 157 may be variously located on the outer surface of the housing 140, and also components mounted on the couplers 151 to 157, that is, the hot water supply pipes 161 and 163 and the heating water pipes. 171 and 173, the safety valve 183, the temperature gauge 181, and the electric heater 198 may also be mounted on the couplers 151 to 157 by changing positions.

Meanwhile, two electric heaters 198 are fastened and fixed to the coupler 157 while being inserted into the coupler 157 formed on the side surface of the housing 140. The electric heater 198 has a socket 199 formed at a rear end thereof and is screwed while the socket 199 rotates in contact with the outside of the coupler 157 while the electric heater 198 is inserted into the coupler 157. . As such, the electric heater 198 inserted into the coupler 157 is located inside the housing 140.

As shown in FIG. 2, three coil parts 160a, 160b, and 160c are formed in the hot water supply pipe 160. The first coil part 160a and the second coil part 160b are formed of the housing 140. Each of the two electric heaters 198 protruding inwardly is positioned to surround each other, and the third coil unit 160c is positioned to surround the outer surface of the combustion chamber 110. 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 drained through the heating water drain pipe 173 through the coupler 154 for the heating water pipe. 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.

On the other hand, the burner 190 is located inside the combustion chamber 110. The burner 190 is supplied with oil and combustion air, and the fuel supply line 193 and the air supply line 195 extend through the combustion chamber 110 and the housing 140 to the outside of the housing 140. The fuel supply line 193 extends to the fuel tank 192 in which oil is stored, and the air supply line 195 extends to the blower 194. As such, the oil stored in the fuel tank 192 is supplied to the burner 190 through the fuel supply line 193, and the compressed air from the blower 194 is supplied to the burner 190 through the air supply line 195. do. The burner 190 atomizes the supplied oil with high-pressure air and atomizes it, and vaporizes the atomized liquid oil with gas and then sprays it with the combustion air through the burner head 191. As such, the gas injected into the burner head 191 is ignited to generate heat together with the flame.

Therefore, the user loads firewood into the combustion chamber 110 to burn or burns oil using the burner 190 to generate heat. In some cases, heat can be generated by burning firewood and oil simultaneously.

In the following description on the relationship of producing the heating water 1 or the hot water supply water using the composite boiler 100 configured as described above, the relationship between the production of the heating water and the hot water water using firewood is given priority. Will be explained.

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

As the fuel is burned in the combustion chamber 110 and the charging container 130 as described above, 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 and rises upward along the combustion chamber 110, at this time, by rotating in a whirlwind form by the density difference inside the combustion chamber 110 do. As combustion gas inside the combustion chamber 110 rotates and rises, the combustion gas is naturally discharged without forcibly discharging the combustion gas, and combustion air naturally flows into the combustion chamber 110 through the through hole 135h of the first 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 increase the thermal efficiency, the length of the heating tube 111 should be long. 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.

On the other hand, the combustion gas exiting the combustion chamber 110 through the chimney 120 enters the cleaning chamber 121.

The airflow of the combustion gas that rises vertically along the chimney 120 in the combustion chamber 110 moves horizontally in the cleaning chamber 121 and moves toward the inlet side of the cleaning chamber 121, that is, the second opening / closing door 125. . As the air flow direction of the combustion gas is changed in this way, the flow rate is somewhat stagnant and the flow rate is lowered. At this time, the heat of the combustion gas is transferred to the heat storage plate 123 mounted in the cleaning chamber 121, and transferred to the heat storage plate 123. The heat is accumulated in the heat storage plate 123, when the temperature of the heating water (1) falls, provides the accumulated heat to heat the heating water (1).

On the other hand, the combustion gas generated while the fuel is burning soot and ash generated by the incomplete combustion of the fuel, soot and ash flows along with the combustion gas, the flow rate of the combustion gas is lowered as the airflow of the combustion gas is changed Accordingly, the ash is loaded to the bottom of the cleaning chamber 121. The soot is attached to the inner side of the heat storage plate 123 or the cleaning chamber 121. When time passes and the cleaning chamber 121 is to be cleaned, the second opening and closing door 125 of the cleaning chamber 121 is opened and the interior of the cleaning chamber 121 is cleaned.

On the other hand, the heating water 1 heated by combustion of 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 combined 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 the proper pressure, the safety valve 183 is discharged to maintain the state of the safe composite 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.

The following describes the relationship between producing heating water and hot water using electric heaters.

The electric heater 198 is heated using the midnight electric power. As the electric heater 198 generates heat as described above, the heating water 1 filled in the housing 140 is heated. When the user needs hot water in this state, when the hot water supply water supply (2) to the hot water supply water supply pipe 161, the hot water supply (2) along the hot water supply pipe 160 and the first coil unit 160a and the first Rapidly heating while passing through the 2 coil part 160b. The hot water supply water 2 heated in this manner is supplied to the user through the hot water supply drain pipe 163.

On the other hand, the heat storage composite boiler 100 according to the present invention can use the heating water (1) heated during the day by heating the heating water with the electric heater (198) at night by using a relatively inexpensive late night power. Therefore, the heat generated from the electric heater 198 is stored in the heating water 1 and used when necessary. In addition, when the temperature of the heating water 1 drops sharply in the middle of the night, the boiler itself senses the temperature of the heating water 1, and heats the electric heater 198 even though the fuel and oil are not supplied. 1) can be heated by heating.

In the resources of the regenerative composite boiler according to the present invention, in the case of a large-capacity regenerative composite boiler having a heating water capacity of 1200 L or more, even if the heating water 1 is not burned for a long time after burning the fire and oil, The combustion chamber 110, the heating tube 11, the chimney 120, the heat storage plate 123 and the cleaning chamber 121 is stored. In particular, the larger the heating water capacity, the larger the surface area of each component is, the greater the amount of heat that can be accumulated. Even after the combustion is completed by the heat accumulated in this manner, the heating water is heated or kept warm for a long time, or the cooling rate is slowed. Therefore, if the heating water is heated with firewood and oil in the early evening, the heating water can be heated until the next morning.

The following describes the relationship between burning oil and producing heating water and hot water.

The electronic pump P of the fuel tank 192 is operated to transfer oil toward the burner 190 through the fuel supply line 193. Then, the blower 194 is operated to blow the compressed air toward the burner 190 through the air supply line 195. The oil flowing into the burner 190 is atomized by the pressure of air, vaporized in the burner 190 and exhausted through the burner head 191 in a gas state. The gas exhausted into the combustion chamber 110 is ignited and burns to generate a flame. Although not shown in the drawings, the igniter in the drawing is a known general igniter using a piezoelectric body.

As such, the flame and heat generated by burning the fuel in the burner 190 produce the heating water 1 and the hot water supply 2 in the same manner as the flame and heat generated when the wood is burned.

Therefore, the user can produce the heating water and the hot water supply as the most efficient energy source according to the economic condition. Meanwhile, LPG or LNG gas may be supplied to the burner in place of oil to be used as a gas boiler.

On the other hand, the components in contact with the heating water 1 and the hot water supply 2 of the components of the composite boiler 100 may be corroded, it 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, the cleaning chamber 121 ) Is made of stainless steel (SUS 304), it is preferable that the hot water supply pipe 160 is a copper tube having good thermal conductivity because hot water is to be heated rapidly. 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 generated by corrosion to block the pipe. And the first opening and closing door 135 and the air conditioning plate 137 and the heat storage plate 123 that is 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, a through hole is formed in the first opening / closing door 135, the nozzle is inserted into the through hole, and the waste oil is injected through the nozzle to combust it.

In the above-described composite boiler, there are many differences in thermal efficiency depending on the size. The following describes the size of the composite boiler in which the composite boiler configured as described above can obtain the best thermal efficiency.

According to the long-term experience of the inventors, in the case of a regenerative composite boiler filled with heating water of about 1200 l capacity, the height of about 1800mm, about 600mm × about 650mm of fireball, about 1300mm of fireball depth, about 1250mm ^{2 in} width, about 1600mm in front and rear, and weight About 1200 kg was found to be the most suitable. Here, the height represents the length remaining after the chimney is removed from the bottom leg of the housing, the width is the bottom area of the charging container and the combustion cylinder, and the front and rear are the length from the front to the rear of the boiler. The regenerative composite boiler of the above capacity has a capacity capable of heating about 40 pyeong.

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.

In the heat storage composite boiler having such a structure, in order to obtain a more efficient heat storage effect, if the refractory brick is loaded inside the combustion chamber, heat is accumulated in the refractory brick at the time of combustion, and the heat accumulated in the refractory brick is used after the end of combustion. Heating water can be heated. As described above, the regenerative composite boiler installed with the refractory brick can be installed to compensate for the small amount of the regenerative heat.

As described in detail above, the heat storage composite boiler of the present invention has an advantage that it can be installed in a small 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 heat storage composite boiler of the present invention has the advantage of having a uniform temperature distribution while heating water is convection by a heating tube, and is provided with 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 in a natural state, there is an advantage that a facility for forcibly exhausting gas or supplying combustion air is not required.

In addition, the heat storage composite boiler of the present invention can use waste oil in addition to firewood as firewood, and can produce heating water and hot water as the most efficient energy source among firewood, oil and electric power.

In addition, the regenerative composite boiler of the present invention accumulates a large amount of heat in the boiler itself frame or additionally installed refractory brick, so that even after the end of combustion, heating or warming the heating water for a long time or lowering the cooling rate to maintain a constant temperature during the decoration. Can produce heating water.
