Abstract

PURPOSE:To restrict an increasing of temperature at the top plate of the main body of a combustion device without using a thermal insulative material by a method wherein a mixing cylinder arranged to pass through the top plate of the main body of the box-like combustion device having suction holes and a nozzle opposing against the lower end of the mixing cylinder at the extremity end arranged at the exhausting port of the top surface of the heat exchanger installed in the main body of the combustion device. CONSTITUTION:High temperature exhaust gas passed through within a heat exchanger 6 and within a muffler 7 increases the speed at the nozzle 5 and the air around the nozzle 5 within the main body 1 of the combustion device is sucked into a mixing cylinder 4 along the guide plate 3 under the effect of ejection. Due to this fact, the surrounding atmosphere is sucked into the main body 1 of the combustion device through the suction holes 2 at the side surface of the main body 1 of the combustion device and the bottom surface of the combustion device. Thus, since the cold surrounding air is always flowed into the surrounding part of the nozzle 5, the increasing of temperature at the top plate 1a is restricted. Further, the high temperature exhaust gas and the air fed into the mixing cylinder 4 and mixed in the mixing cylinder 4, their temperature is decreased and their concentration is decreased, and then they are exhausted to the surrounding atmosphere. In this way, the temperature of the exhaust gas is decreased and the temperature of the top plate 1a is decreased.

度上昇が抑えられる。The exhaust system of the present invention includes a box-shaped combustion device main body having an intake hole, a mixing cylinder provided through the top plate of the combustion device main body, and a heat exchanger disposed inside the combustion device main body. It is provided at the exhaust port on the top surface and the tip is located at the bottom end of the mixing cylinder.
According to this configuration, the exhaust gas flows from the nozzle into the mixing tube, and the ejector q3 causes the nozzle (D ii
: The vitality of the i side is sucked in. In this case, since the lower end of the mixing cylinder is provided inside the combustion device main body, outside air constantly flows into the combustion device main body, and the warmed air inside the combustion device main body is discharged to the outside together with the exhaust gas. Therefore, the rise in temperature of the top plate can be suppressed.

A mixing cylinder 4 is provided to pass through the top plate 1a, and an exhaust tongue 9 is placed over the upper end of the mixing cylinder 4. The mixing cylinder 4 has a lower end,
It has an umbrella-shaped guide plate 3 that spreads downward. A nozzle 5 of a heat exchanger 6 is provided at a distance below the guide plate 3. The heat exchanger 6 has a muffler 7 inside thereof through which the exhaust gas passes, and the nozzle 5 marked i1 is directly attached to the exhaust port 8 at the upper center end of the muffler 7. The diameter of the nozzle 5 is smaller than the inner diameter of the mixing cylinder 4.

ことができる。The high-temperature exhaust gas that has passed through the inside of the operating heat exchanger 6 and the inside of the silencer 7 increases its velocity at the nozzle 5, and due to the ejector effect, air around the nozzle 5 is directed to the guide plate 3 inside the combustion device main body l. It is sucked into the mixing cylinder 4 along the line. Therefore, outside air is sucked into the combustion apparatus main body 1 through the intake holes 2 on the ii1 side and the bottom of the combustion apparatus main body 1. Therefore, since cold outside air constantly flows into the area around the nozzle 5, the top plate 1a
temperature rise is suppressed. Further, the high-temperature waste waste and air sent into the mixing cylinder 4 are mixed within the mixing cylinder 4, lowered in temperature and temperature, and discharged to the outside. In this way, the temperature of the top plate 1a can also be lowered by lowering the temperature of the emitted exhaust gas. 'Furthermore, since the exhaust top 9 is attached to the upper end of the mixing cylinder 4, the waste exhaust plate b1 can be further lowered. The exhaust top 9 sucks outside air from the surroundings by the flow of exhaust gas from the upper end of the mixing cylinder 4. In addition, since the mixing cylinder 4 is provided in the combustion apparatus main body l so that outside air is sucked in from the lower end, there is no need to install a tall exhaust top 9, and the appearance can be made neat.

が得られる。Figure 2 shows an example of a pond. In this example, the guide plate 3' at the lower end of the mixing cylinder 4' is formed into a cylindrical shape whose entire diameter is larger than that of the mixing cylinder 4'. The nozzle 5' has a constricted middle portion. The other configurations are the same as the first sister example. Even in this case, the same effect as the first embodiment can be obtained.
