【発明の詳細な説明】 ＜産業上の利用分野＞ 本発明はバーナ装置に係り、特に点火ミスを防止し得る
ボイラ用バーナ装置に関する。Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a burner device, and more particularly to a burner device for a boiler that can prevent misfire.
＜従来の技術及びその問題点＞ バーナの着火法には直接点火方式と点火バーナを用いる

が採用されている。<Prior art and its problems> There are two types of ignition methods for a burner, a direct ignition method and a method using an ignition burner. However, since the direct ignition method usually uses a spark, it can be ignited even in a narrow ignition area for household use. It is applied only to small burners of general type and it is difficult to set the ignition position in a general industrial burner, and if ignition fails, a large amount of gas may flow out at one time and there is a risk of explosion, so the ignition burner method is used instead of the spark type. .

８の放電により、火災検出器が誤作動する場合もある。FIG. 1 shows an example of the arrangement of the ignition burner and the main burner of the boiler gas burner. When igniting the burner, first, fuel is flown through the fuel pipe of the ignition burner 2, and this fuel is ignited by an ignition device such as a pulse igniter to form a flame for ignition. Next, when the fuel valve for the main burner is opened to inject fuel from the fuel nozzle 3 for the main burner, the fuel injected from the fuel nozzle near the ignition fire is ignited first, and this fire is successively emitted from other nozzles. Then, the injection fuel is changed to the injection fuel, and the ignition of all burners is completed. FIG. 2 shows an example of the tip of the ignition burner. The fuel for ignition is guided to the tip of the ignition burner by the ignition burner fuel pipe 6. The ignition plug 8 of the pulse igniter 7 of the ignition device has a tip projecting into the fuel flow as shown in the figure at the time of ignition, but is housed in the outer cylinder of the pulse igniter 7 except at the time of ignition. There is. A pulse arc (6 to 7 pulses / sec) is generated at the tip of the spark plug 8 by the pulse igniter 7 at the timing when the fuel flow reaches the tip of the ignition burner, and the mixed flow of fuel and air is ignited. By the way, the pulse arc is generated between the tip of the spark plug 8 and the ground, but since the position is localized, the tip position of the spark plug 8 is finely adjusted in order to reliably ignite the fuel flow. There is a need to. Further, if the arc generation position and the fuel flow passage position deviate from each other due to the pressure change of the fuel flow, ignition may not occur. Also, in order to prevent the tip of the spark plug from burning out, it is necessary to project the spark plug only during ignition and to pull it out except during ignition. It may lead to ignition failure. On the other hand, the life of the spark plug 8 is currently as short as about 200 to 300 hours due to problems such as metal deterioration. Further, the fire detector may malfunction due to the discharge of the spark plug 8.

A frame container 17 is formed near the tip of the main burner fuel nozzle 3 so that the central axis of the fuel nozzle 3 is substantially the same as that of the nozzle 3. There is. Reference numeral 10 denotes an ignition device attached to the frame container 17, which is a ceramic heater as described later. 21 is a premix ignition chamber formed to cover the ignition device 10, 19 is an air hole for supplying air to the premix ignition chamber 21, 18 is an igniter support portion, 20 is fuel for the premix ignition chamber 21 Fuel holes to be supplied, 14 is a main hole, 15 is a sub hole, and 16 is an air hole formed in the frame container 17.
この装置の作動につき第３図も含めて説明する。The operation of this device will be described with reference to FIG.
例えば、上述のバーナを燃料量300Nm3/hのガス燃焼装置

て予混合着火室21に燃料が噴射される。For example, when the above burner is a gas combustion device with a fuel amount of 300 Nm 3 / h, the fuel gas sent through the burner source valve 11 and the burner inlet valve 26 (hereinafter, butane gas will be described as an example) is the main burner. From fuel nozzle 3 for main hole 14 and sub hole 15
The fuel is injected into the furnace through the combustion hole for ignition 20 and at the same time, the fuel is injected into the premix ignition chamber 21 through the combustion hole 20 for ignition.

ーナスロート５部へ供給され（第１図参照）、同時に点
火用空気孔19を経由して予混合着火室21に供給される。Combustion air is supplied from the air register 1 to the impeller 4 and the burner throat 5 (see FIG. 1), and at the same time, supplied to the premix ignition chamber 21 via the ignition air hole 19.
なお、予混合着火室21における空気比は、着火燃焼を確
実に行せるため空気比１〜1.5に設定するのが望ましい
が、空気比1.1に設定した場合点火燃料用として消費す
る燃料量は0.01〜0.1Nm3/h程度で十分である。The air ratio in the premixing ignition chamber 21 is preferably set to an air ratio of 1 to 1.5 in order to ensure ignition combustion, but when the air ratio is set to 1.1, the amount of fuel consumed for ignition fuel is 0.01. Approximately 0.1 Nm 3 / h is sufficient.
次にこの装置において、燃料ガス圧が7000mmHg、燃焼用
空気の軸方向速度10m/秒、点火用燃料量0.1Nm3/hとし
て、予混合着火室21内の空気比を1.1と設定するために
必要な空気孔19及び燃料孔20の孔径寸法を以下に記述す
る。Next, in this device, the fuel gas pressure is 7000 mmHg, the axial velocity of combustion air is 10 m / sec, the ignition fuel amount is 0.1 Nm 3 / h, and the air ratio in the premix ignition chamber 21 is set to 1.1. The required hole diameter dimensions of the air hole 19 and the fuel hole 20 are described below.
まずガス圧7,000mmHgで、0.1Nm3/hの燃料量を流すのに
必要な燃料供給孔面積はブタンガスの場合約0.1mmとな

比1.1にするには、ブタンガスの場合約24倍の空気量が
必要であるが、空気孔19を通過する空気流速を10m/秒と
すると、空気孔19の空気通過面積は約0.7cm2である。First, at a gas pressure of 7,000 mmHg, the fuel supply hole area required to flow a fuel amount of 0.1 Nm 3 / h is about 0.1 mm for butane gas. The gas flow velocity at this time is 110 m / sec. In the case of butane gas, about 24 times the amount of air is required to achieve an air ratio of 1.1, but if the air flow rate through the air holes 19 is 10 m / sec, the air passage area of the air holes 19 is about 0.7 cm. Is 2 .

る。 Where t: radial height of the premixed ignition chamber, l: axial height of the premixed ignition chamber, the flow velocity of the fuel gas is usually as high as 80 to 150 m / sec, but injected into the premixed ignition chamber 21. The fuel is decelerated by colliding with the side wall of the ignition chamber 21 and the like, and is appropriately premixed with air in the process to have a flow velocity of about 1 to 5 m / sec, which facilitates ignition.

After opening 26, the control device 12 sends an energization start signal to the power supply device 13 when the fuel gas and the air are mixed well after a certain time delay. By this signal, a current is applied by the power supply device 13 to the ignition device 10 (hereinafter described as "ceramic heater") installed in the premix ignition chamber 21. Here, since the premix ignition chamber 21 is a low flow velocity region in which the fuel and the combustion air are premixed at a ratio equal to or higher than the theoretical air ratio, in the case of gas fuel, it is possible to ignite with energy of about 2 Joules, and the ceramic heater 10 If the amount of heat generation is set to 2 to 100 W, it will ignite reliably. Accordingly, by applying a current of a certain amount or more to the heater, a flame is formed at the exit portion of the premix ignition chamber 21, which then ignites the fuel injected from the auxiliary hole and the main hole, and this flame is successively generated. The fuel injected from the other nozzles is ignited, and the ignition of the entire burner device is completed.

The conductive portion 22 is united by the red heating portion 24 in which the thickness of the heater tip is reduced to increase the electric resistance.
Therefore, when a voltage is applied to the electrode portion 25, a current flows through the conductive portion, and the red heating portion 24 having the thinned tip end glows red. The applied voltage may be DC or AC, and the tip may glow red (approx.
The applied voltage value required to make it 900 ° C. or higher) can be set by the resistance value length and cross-sectional area of the red heating part 24.

あり、電源装置が極めて簡易化される。The applied voltage value of the conventional pulse igniter is a high voltage of 1 KV or more, whereas the ceramic heater may have a maximum of about 20 V, and since it may be an AC power supply, an explosion-proof structure is not required, and the power supply device is extremely simplified. .

Since it is cooled to 00 ℃, it is not necessary to have a heat resistant structure. Furthermore, the ceramic heater has excellent heat resistance of 1200 to 1300 ° C originally, and it can be left around the injection port even after ignition, and the ceramic heater part corresponding to the ignition plug of the pulse igniter can be projected or pulled out. It does not require a driving mechanism such as a screw and has a long life.
