Is a fuel cell. The reformer K has a catalyst K1 inside, and reforms the raw material gas G supplied from the outside by heating the catalyst K1 with the burner A at the lower part. The reformed fuel gas is supplied to the fuel cell E and reacted with oxygen in the air for power generation, while the unreacted gas is supplied to the reformer burner A.
And is burned. The reformer burner A heats the catalyst by burning liquid fuel such as methanol at the time of starting the reformer and at the time of additional cooking, so that the unreacted gas is sufficiently supplied from the fuel cell E side. , The catalyst is heated by burning only the unreacted gas. FIG . 1 shows a burner A for a reformer according to the present invention.
FIG. 2 is a sectional view showing an embodiment, and FIG.
It is. This embodiment roughly includes a burner device A.
Burner body with built-in body casing 1 and heater 2
3, a flame forming cylinder 4 disposed in the burner body 3,
A heat conductor 5 connected to the upper surface of the burner body 3;
An unreacted gas jacket 7 provided in the upper part of the main body 1
Has been established. The heater 2 is formed in an annular shape by, for example, an electric heating element that self-heats when energized, and has a burner body 3.
Is inserted within the thickness of the inner wall and can be energized through an energizing wire communicating with the outside. Burner body 3
1 is formed of a material having good heat conduction efficiency and is formed in a bowl shape with a bottom and an opening at the upper side as shown in FIG. A supply portion 3a for supplying the liquid fuel and air necessary for combustion of the fuel is opened in a conical hole shape, and the liquid fuel supplied from the liquid fuel nozzle 6 described later by the heat energy heated by the heat generated by the heater 2 Is vaporized and mixed with air, and then supplied to the flame forming cylinder 4 as a mixed gas. The flame forming cylinder 4 is disposed above the supply portion 3a of the burner body 3, and is composed of a cylinder having a predetermined height as shown in detail in FIG. A fixing flange 4b is provided on the outer periphery of the opening, and a large number of flame forming holes 4c are formed in the peripheral wall surface 4a of the cylindrical body. It collides with the upper surface of the cylinder 4 and
The flame is radiated from the flame forming hole 4c and becomes a combustion flame, and the inner peripheral surface of the burner body 3 opposed thereto is directly heated, and the temperature of the burner body 3 is raised to a temperature required for the liquid fuel to vaporize. I have. The heat conductor 5 is formed of a cylindrical body (in the embodiment, a conical cylinder) having upper and lower openings opened and fixed to the upper end surface of the burner body 3. The liquid fuel nozzle 6 is a relatively thin tube, and is supplied via a supply unit 3 a for supplying liquid fuel (aqueous methanol solution in this embodiment) stored outside the main body 1 into the burner body 3. Are provided inside the burner body 3. The unreacted gas jacket 7 is an annular cylinder having an annular closed space inside, and is fitted and connected to the upper part of the burner body 3. An unreacted gas supply port 7d for introducing unreacted gas from an external fuel cell into the internal space is provided on a part of the outer periphery of the unreacted gas jacket 7, while
On the inner peripheral side, a number of gas ejection holes 7d are formed so as to face the outer periphery of the heat conductor 5. In addition, the annular outer peripheral surface of the unreacted gas jacket 7 is extended upward as it is, and a number of secondary air intake holes 7e are formed in the cylindrical portion 7c formed by the extended extension. According to the above configuration, first, the heater 2 is energized to generate heat, and the heat energy preheats the burner body 3 itself. When the burner body 3 rises to the liquid fuel vaporization temperature, the fuel nozzle 6 The supplied liquid fuel is vaporized in the bottom area of the burner body 3 and mixed with air introduced from the supply section 3a, and is supplied to the flame forming cylinder 4 as a mixed gas. The mixed gas rises and collides with the upper surface of the flame forming cylinder 4, radiates to the side from the flame forming hole 4 c, becomes a combustion flame, and rises so as to lick the opposing inner peripheral surface of the burner body 3. While burning. The burner body 3 is directly heated by the burning, and when the burner body 3 is heated to a set temperature equal to or higher than the vaporization temperature, the power supply to the heater 2 is cut off, and the self-heating of the heater 2 is stopped. The supplied liquid fuel continues to be vaporized only by the heated heat of the burner body 3, and heat-back of the heat energy that rises so as to lick the inner peripheral surface of the burner body 3 is performed. The unreacted gas supplied from the fuel cell E and ejected from the gas ejection holes 7d of the unreacted gas jacket 7 is ignited by this flame, and the temperature (vaporization temperature) is maintained at the same time. The fuel is mixed with the secondary air to start combustion. Then, the combustion flame rises along the cylindrical portion 5b of the heat conductor 5 to become a high-temperature combustion gas, and heats the catalyst K1 while flowing through the reformer K to be supplied into the reformer K. Fuel gas E by reforming the raw material gas G
Of the heat conductor 5 heated by the combustion of the unreacted gas is transmitted again to the burner body 3 (heat back), and the temperature of the burner body 3 is reduced. The heat is always stored at a predetermined temperature at which the liquid fuel can be vaporized. When the endothermic reaction becomes active and replenishment of heat is required due to an increase in the load of the reformer K or the like, the liquid fuel can be vaporized and burned without heating the heater 2 each time, thereby making it possible to perform additional cooking. It has become. Thus, unlike the prior art, it is possible to reliably prevent the liquid fuel from vaporizing at an uneven position or incompletely burning, and to reduce the power consumption for the heater 2 while reducing the supplied liquid fuel and its combustion. The accompanying thermal energy can be used effectively. As shown in FIG. 4, the flame forming cylinder 4 may be provided with a flame forming hole 4c in the flange portion 4b. In this case, the flame radiating to the side is directed upward to conduct heat. With the benefit of promoting heating of body 5. Further, by forming a large number of radial split grooves (slits) 5a in the cylindrical portion 5b of the heat conductor 5, the area of burning by a flame can be increased, which is advantageous in that heating efficiency is promoted. In this case, the slit 5a is desirably provided at a position opposing the gas ejection hole 7d of the unreacted gas jacket 7 and the authentic surface. As described above, according to the present invention, by devising the structure of the flame forming cylinder, the heat back action of the heat energy can be effectively used, and the present invention is more effective than the conventional one. Liquid fuel can be eliminated incompletely, and even when the endothermic reaction increases, such as when the load suddenly increases, the corresponding liquid fuel can be immediately re-cooked without heating the heater each time. A remarkable effect of reliably maintaining the quality gas composition and the required generation amount can be obtained.
