Description

【考案の詳細な説明】本考案はボイラ、工業加熱炉等の燃焼炉内の燃焼状態を
監視する’１’、ｖ、を炉壁に取付けるための炉内監
視１’、ｖ、取付台座に係る。[Detailed description of the invention] The present invention is based on a furnace wall monitor 1', v, which monitors the combustion state in a combustion furnace such as a boiler or an industrial heating furnace, and a mounting pedestal. It depends.

従来の台座について第１図ないし第３図に基づいて説明
する。A conventional pedestal will be explained based on FIGS. 1 to 3.

炉壁■に台座■を敷き、その上に１’、ｖ、装置■が
取付けられている。A pedestal (■) is placed on the furnace wall (■), and 1', v, and the device (■) are mounted on it.

台座■は炉壁管■の開口部より炉内■の高温ガスに面し
ダイレクトラジエーションを受けるため、クーリングエ
アで冷却されている。The pedestal ■ faces the high-temperature gas in the furnace ■ from the opening of the furnace wall tube ■ and receives direct radiation, so it is cooled by cooling air.

冷却機構は、供給管■より供給されたエアはエアチャン
バー■にはいり、台座■に十字に切った溝■を流れて台
座■を冷却し、炉■内に流出する構造になっている。The cooling mechanism has a structure in which air supplied from the supply pipe (■) enters the air chamber (■), flows through a cross-cut groove (■) in the base (■), cools the base (■), and then flows out into the furnace (■).

台座■には十字の溝■にしか、エアが流れないので溝が
切ってない面は、炉内のダイレクトラジエーションのた
め焼損し易く、エア供給管■より遠い域はエアの廻りが
少く十分な冷却効果が期待できないので高温になり、そ
のため、台座■は耐熱性の特殊材で形成しなげればなら
なかった。Air can only flow through the cross-shaped grooves on the pedestal ■, so the surface without grooves is prone to burnout due to direct radiation inside the furnace, and the area farther from the air supply pipe ■ has less air circulation and is not sufficient. Since the cooling effect could not be expected, the temperature would reach high temperatures, so the pedestal (2) had to be made of a special heat-resistant material.

とができる炉内監視Ｔ、Ｖ、取付台座を提供している。Therefore, the present invention was devised to prevent the pedestal from being burnt out by allowing cooling air to flow throughout the entire area of the pedestal, and to provide a device that does not require the pedestal to be made of a special material. , is attached to the opening in the furnace wall, an air chamber is arranged around it, 1', v,
The inside of the furnace monitoring 1", v, mounting pedestal on which the device is mounted is shaped like a hollow, and a substantially spiral-shaped partition plate is arranged in the hollow part to provide a spiral-shaped air passage. , the interior of the air chamber and the air passage are communicated with each other, and an air outlet is provided in the center of the dome, the pedestal is hollow, and the hollow part is partitioned by a substantially spiral partition plate. Since we have provided a shaped air passage, the cooling air enters the hollow part from the air chamber, flows through the air passage, and blows out from the outlet, so the cooling air flows over the entire area of the pedestal and cools the pedestal. We provide furnace monitoring T, V, and mounting pedestals that prevent burnout, do not require the pedestal to be made of special heat-resistant material, and can reduce manufacturing costs.

次に本考案を第４図ないし第１図に示すｌ実施例に基づ
いて具体的に説明する。Next, the present invention will be specifically explained based on an embodiment shown in FIGS. 4 to 1.

炉壁■の開口部に台座■が取付げられ、台座■の周囲に
はエアチャンバー■が設げられ、エアチャンバー■には
空気を送る供給管■が取付けられている。A pedestal (■) is attached to the opening of the furnace wall (■), an air chamber (■) is provided around the pedestal (■), and a supply pipe (■) for sending air is attached to the air chamber (■).

台座■には、’Ｉ’、ｖ、装置■が取付げられ、炉壁
の開口部を通して炉内を監視するようになっている。'I', v, and device (2) are attached to the pedestal (2) to monitor the inside of the furnace through an opening in the furnace wall.

る。The inside of the pedestal ■ is formed into a hollow shape, and a cooling air inlet ■ is provided at its corner. Starting from the cooling air inlet ■, there is a circular opening in the center of the pedestal ■, adapted to the viewing angle. Facing part (), the hollow part is spirally partitioned into approximately equal parts by partition plates O to form a cooling air passage 0, and an air outlet 0 is provided at the end of the spiral cooling air passage 0.
Cooling air supplied into the pedestal ■ from the cooling air inlet ■ is circulated through the passage 0, which is spirally partitioned by a partition plate inside the pedestal ■, over the entire surface of the pedestal ■, and then
While cooling, it is ejected into the furnace through the outlet 0 and from the opening ①.

特殊な耐熱材で形成することを不要としたものである。The inside of the pedestal ■ is partitioned into approximately equal parts by a partition plate O in a spiral shape so that there is no dead space, forming a passage 0. Cooling air flows through the passage 0, so that the pedestal ■ is evenly cooled and the air is Since there is no stagnation and the flow rate is high, a sufficient cooling effect can be obtained, which prevents the pedestal (1) from burning out and eliminates the need for the pedestal to be made of a special heat-resistant material.
