Alternatively, the cooling pipes 1 having fins 3 are connected to each other, and the plurality of cooling pipes 1 form the side wall part 4 and the furnace bottom part 5 of the combustion furnace. .
炉底部５には、開口部６が形威され、炉底部５は開口部
６に向って下方向に傾斜している。An opening 6 is formed in the furnace bottom 5, and the furnace bottom 5 is inclined downward toward the opening 6.
開口部６の下方には、内部に海水等の液体を貯えたタリ

カは側壁部４の冷却管１から剥離し落下する。This talin force gradually lengthens and increases, and when it becomes large enough, the talin gas separates from the cooling pipe 1 of the side wall portion 4 and falls due to the vibrations of the combustion furnace and the weight of the talin force itself.
落下したタリン力は、炉底部５を形威した冷却管１に沿

The cooling pipe 1 collides with the tip of the cooling pipe 1 forming the opening 6.
furthermore, the talin force from the opening 6 to the hopper 7
When it falls into the seawater inside the reactor, seawater splashes up, and the seawater adheres to the cooling pipe forming the reactor bottom 5, rapidly cooling the cooling pipe 1, or the salt in the seawater corrodes the cooling pipe 1. There were drawbacks such as the occurrence of
そこで本考案は、上記欠点を除くことを目的としてなさ

ィンを取付けたことを特徴とする燃焼炉を提供するもの
である。The present invention has been made to eliminate the above-mentioned drawbacks, and provides a combustion furnace characterized in that fins are attached to the inside of the cooling pipe that defines the bottom of the furnace.
本考案を第４図ないし第６図に示す実施例に基づいて具
体的に説明する。The present invention will be specifically explained based on the embodiments shown in FIGS. 4 to 6.
燃焼炉の炉底部１５を形或する冷却管１１の上方側にフ

一体或形されるものでも、溶接等により固着されたもの
でもよい。The fins 18 attached to the cooling pipe 11 may be formed integrally with the cooling pipe 11 or may be fixed by welding or the like.
その他の構造は従来のものと同じであり、ここでは詳細
説明は省略する。The rest of the structure is the same as the conventional one, and detailed explanation will be omitted here.
側壁部１４の冷却管１１に燃焼後の灰分がふれ、灰分が
冷却されてタリン力が形成される。The ash after combustion comes into contact with the cooling pipe 11 of the side wall portion 14, and the ash is cooled to form a talin force.
このクノンカは側壁部１４で威長、増大し、ある程度の
大きさになると、燃焼炉の振動、あるいは、タリンカ自
体の自重により側壁部１４の冷却管１１から剥離・落下
する。This kunonka grows and increases in size on the side wall 14, and when it reaches a certain size, it peels off and falls from the cooling pipe 11 of the side wall 14 due to the vibration of the combustion furnace or the weight of the kunonka itself.
炉底部１５の冷却管１１上にタリン力が落下するが、タ
リン力は冷却管１１のフイン１８に衝突する。The talin force falls onto the cooling pipe 11 in the furnace bottom 15, but the talin force collides with the fins 18 of the cooling pipe 11.
フイン１８に衝突したタリンカは、衝撃をうけ、破砕さ
れ小さくなる。The tarinka that collides with the fin 18 receives an impact and is crushed into small pieces.
小さくなったタリンカは炉底部１５上を滑り落ち、ある

で、冷却管１１の急冷、腐食が防止できるものである。According to this combustion furnace, since the fins 18 are provided in the cooling pipe 11 of the furnace bottom part 15, the rigidity of the cooling pipe 11 of the furnace bottom part 15 is increased, and bending of the cooling pipe 11 due to the impact of falling tarinka can be prevented. Furthermore, the talinka can be crushed by the fins 18, preventing the talin force from directly colliding with the cooling pipe 11 and preventing the cooling pipe 11 from being damaged.
In order to reduce the amount of seawater splashed when the No. 11 heclinker falls, seawater is prevented from adhering to the cooling pipe 11, so that rapid cooling and corrosion of the cooling pipe 11 can be prevented.

い。As described above, in this embodiment, the cooling pipes 11 are connected by the plate material 12, or the cooling pipes 11 having fins 13 are connected to each other by the fins 13, and the fins 18 are attached to the upper side. However, as shown in FIGS. 7 and 8, the rigidity may be further increased by providing fins 18, 18' on both the upper and lower sides.

炉を提供するものである。In short, the present invention provides a combustion furnace in which the wall is formed by a large number of cooling pipes and the bottom of the furnace is inclined so that the tarinka falls to the bottom. The present invention provides a combustion furnace characterized in that it is equipped with fins that extend from one side to the other.

防止している。According to the combustion furnace of the present invention, since the fins are attached to the cooling pipe at the bottom of the furnace, the rigidity of the cooling pipe 15 is increased, and bending of the cooling pipe due to the talin force falling to the bottom of the furnace can be prevented. Since it prevents direct collision with the pipe, damage to the cooling pipe can be prevented, and furthermore, the Tallinn force can be broken into small pieces by colliding with the fins when falling.
When the clinker falls from the bottom of the furnace to the clinker hopper, the droplets of liquid such as seawater in the clinker hopper are kept small, preventing the liquid from adhering to the cooling pipes and preventing rapid cooling and corrosion of the cooling pipes.
