Description
- The present invention relates to a gas boiler in which overheating of a burner flange and gas leaking is prevented, and more particularly, to a gas boiler having a structure that is capable of being preventing a burner for receiving a pre-mixed gas from a gas supply chamber to burn the pre-mixed gas from being overheated.
- Boilers used for providing heating and hot water in general homes may be categorized into oil boilers and gas boilers according to fuel for use. The gas boilers may use LPG as fuel. However, LNG is mostly being used for the gas boilers, which is clean fuel that is capable of minimizing air pollution because the LNG contains few sulfur contents when compared to diesel fuel or kerosene. In the oil and gas boilers, fluids are heated by using heat generated while oil and gas are being oxidized, and the fluids heated to be heat-exchanged circulate to increase an indoor temperature and supply hot water.
- Recently, condensing boilers to which condensing heat exchangers are applied so that a burner is disposed on a top or side surface of a heat exchanger to allow a combustion gas to flow downward, and a temperature of an exhaust gas of the heat exchanger is reduced to a dew point temperature or less, are being used.
- However, when the burner burns the gas in the gas boiler, flames of the burner generated by the combustion may be shorten in length according to low load combustion. If the flames of the burner is shorten in length, the flames may overheat a surface of the burner. In particular, in the downward combustion type such as the condensing boiler, since the flames of the burner stay very close to the surface of the burner, the surface (especially, a flange of the burner) of the burner is further overheated. Also, in this high temperature environment, there is a small choice in materials of sealing member.

Theburner 110 may receive a pre-mixed gas to burn the pre-mixed gas. Theburner 110 may receive the pre-mixed gas in which air is pre-mixed with a gas at an optimal combustion mixing ratio from thegas supply chamber 130 that will be described later. The pre-mixed gas may be completely burnt. Thus, the burner has high combustion efficiency and may realize complete combustion at a low air ratio.

burner 110 and thegas supply chamber 130. However, theburner 110 may be slightly separated from thegas supply chamber 130 without being shape-matched due to the installation of the sealing member. Thus, the sealingmember 150 according to the present invention solves the limitation. Therefore, theburner flange 111 of theburner 110 may be completely shape-matched and coupled to thechamber flange 131 of thegas supply chamber 130 so that theburner flange 111 surface-contacts thechamber flange 131. More particularly, the sealingmember 150 is disposed between theburner flange 111 and thechamber flange 131 when theburner flange 111 is shape-matched to thechamber flange 131. Thus, agroove 133 is defined in thechamber flange 131 so that the sealingmember 150 is disposed therein. - The sealing
member 150 includes abody 151, aprotrusion 153 formed on thebody 151. Thebody 151 has a width that is less than a height of thegroove 133 so that thebody 151 is inserted to the groove 13. Thebody 151 may have a column shape having a circular or rectangular section and various shapes. - A plurality of
protrusions 153 protruding from thebody 151 is formed on thebody 151. When the sealingmember 150 is installed between theburner 110 and thegas supply chamber 130, one portion of theprotrusions 153 may be inclined toward an inner surface of thegroove 133 defined in thechamber flange 131 of thegas supply chamber 130, and the other portion of theprotrusions 153 may be inclined toward theburner flange 111 of theburner 110. - Particularly, referring to
FIG. 4 , theprotrusion 153 of the plurality ofprotrusions 153, which is formed toward thechamber flange 131, may be inclined upward from thebody 151. Also, theprotrusion 153 of the plurality ofprotrusions 153, which is formed toward theburner flange 111, may be inclined downward from thebody 151. That is, the plurality ofprotrusions 153 are formed toward the insides of thegas supply chamber 130 and theburner 110. - When the sealing
member 150 is installed between theburner 110 and thegas supply chamber 130, the plurality ofprotrusions 153 are disposed and installed toward the insides of theburner 110 and thegas supply chamber 130. The sealingmember 150 may have a height that is greater than that of thegroove 133 by the plurality ofprotrusions 153. However, since the sealingmember 150 is formed of a flexible rubber material, the plurality ofprotrusions 153 may flexibly move to allow the sealingmember 150 to be installed between theburner 110 and thegas supply chamber 130. That is, when the sealingmember 150 is installed to thegroove 133, as illustrated inFIGS. 3 and4 , the plurality ofprotrusions 153 of the sealingmember 150 may be installed to thegroove 133 while being lain toward thebody 151 in an arrow direction. - Thus, the
burner flange 111 of theburner 110 may be perfectly shape-matched and coupled to thechamber flange 131 of thegas supply chamber 130 even though the sealingmember 150 is installed, and theburner flange 111 may surface-contact thechamber flange 131. Since theburner flange 111 surface-contacts thechamber flange 131, if a surface of theburner 110 is overheated because flames of theburner 110 have short lengths due to the combustion with a low heat generation amount, heat-exchanging may be performed between theburner flange 111 and thechamber flange 131 to prevent theburner 110 from being overheated. - The pre-mixed gas supplied from the
gas supply chamber 130 to theburner 110 may leak between theburner 110 and thegas supply chamber 130. However, as described in the present invention, when the sealingmember 150 is disposed between theburner 110 and thegas supply chamber 130, the leakage of the pre-mixed gas may be prevented by the sealingmember 150. Particularly, since the plurality ofprotrusions 153 formed on the sealingmember 150 are formed toward the inside thegas supply chamber 130 and theburner 110, the plurality ofprotrusions 153 may prevent the pre-mixed gas from leaking once again. - A gas boiler according to another embodiment of the present invention is illustrated in
FIGS. 5 to 8 . Like reference numerals in the foregoing embodiment denote like elements, and thus differences between the foregoing embodiment and the following embodiment will be mainly described. - If the pre-mixed gas is burnt in the
burner 110, the flames of the burner may be shorten in length at the time of low load combustion to overheat the surface of theburner 110. In order to this limitation, the gas boiler may further include aheat dissipation fin 170. As illustrated inFIGS. 5 and6 , theheat dissipation fin 170 is disposed between theburner 110 and thegas supply chamber 130. More particularly, theheat dissipation fin 170 has one end that is fixed to theburner flange 111 and the other end that extends toward the inside of thegas supply chamber 130. The other end of theheat dissipation fin 170 extending toward the inside thegas supply chamber 130 contacts the pre-mixed gas supplied from thegas supply chamber 130. Here, since the pre-mixed gas has a low temperature, heat-exchanging between the other end of theheat dissipation fin 170 cooled by the pre-mixed gas and the one end of theheat dissipation fin 170 fixed to theburner flange 111 may be performed to cool theburner 110. - Referring to a detailed shape of the
heat dissipation fin 170 ofFIG. 7 , theheat dissipation fin 170 includes afirst plate 171 fixed to theburner flange 111 to extend toward the inside of theburner 110 and asecond plate 172 extending from a front end of thefirst plate 171, wherein thesecond plate 172 is inclinedly bent upward toward thegas supply chamber 130 when theheat dissipation fin 170 is installed between theburner 110 and thegas supply chamber 130. - The second plate contacting the pre-mixed gas may be bent several times while alternately forming a
convex part 172a and aconcave part 172b to increase a contact area with the pre-mixed gas. Referring toFIG. 7 , each of theconvex part 172a and theconcave part 172b is sharply bent and has a shape such as a thread. -
FIG. 8 is a view illustrating a modified example of a heat dissipation fin 170'. Referring toFIG. 8 , although the heat dissipation fin 170' includes first and second plates 171' and 172' like as the above-describedheat dissipation fin 170, each of aconvex part 172a' and aconcave part 172b' formed in the second plate 172' has a shape different from that ofFIG. 7 . Although each of theconvex part 172a and theconcave part 172b of theheat dissipation fin 170 ofFIG. 7 has a sharp shape such as a thread as described above, each of theconvex part 172a' and theconcave part 172b' of the heat dissipation fin 170' ofFIG. 8 has a curved surface. - The
second plates 172 and 172' are not limited to the shapes ofFIGS. 7 and8 and may have various shapes capable of increasing a contact area with the pre-mixed gas. - Since each of the
heat dissipation fins 170 and 170' has to be easily cooled when each of theheat dissipation fins 170 and 170' contacts the pre-mixed gas and be heat-exchanged with theburner 110 to which each of theheat dissipation fins 170 and 170' are fixed, it is preferable that each of theheat dissipation fins 170 and 170' may be formed of a metal material having good heat transfer efficiency or a heat conductive plastic material. - Like this, when each of the
heat dissipation fins 170 and 170' is disposed between theburner 110 and thegas supply chamber 130, as described above, each of theheat dissipation fins 170 and 170' may be cooled while contacting the pre-mixed gas supplied from thegas supply chamber 130 to cool theburner 110 through the heat-exchanging between each of theheat dissipation fins 170 and 170' and theburner 110. Particularly, at the time of low load combustion, when the pre-mixed gas is burnt by theburner 110, the flames of theburner 110 may be shorten in length to overheat the surface of theburner 110. However, theheat dissipation fin 170 may prevent the surface of theburner 110 from being overheated. - When the surface of the
burner 110 is overheated, the sealingmember 150 disposed between theburner 110 and thegas supply chamber 130 to prevent the pre-mixed gas from leaking may have a small choice of materials. Particularly, when the surface of theburner 110 is overheated, a sealing member formed of a material having improved heat-resistance has to be provided. Thus, the sealing member has a small choice of materials and also is increased in material cost or production cost due to the use of a high-functional material. Therefore, when theheat dissipation fin 170 is disposed between theburner 110 and thegas supply chamber 130, the overheating of the surface of theburner 110 may be prevented through the heat-exchanging. Thus, the sealingmember 150 disposed between theburner 110 and thegas supply chamber 130 may have a wide choice in material and a cost saving effect. - While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and details may be made therein without departing from scope of the present invention as defined by the following claims.
