Zusammenfassung: | PROBLEM TO BE SOLVED: To provide a long-durable apparatus that physically protects heat sensors exposed to high temperature and corrosive environment, accurately measures temperature, allows no accumulation of slag, and endures physical contact with its surroundings.SOLUTION: In a temperature measuring system for two-stage slagging gasifiers, the first stage gasifier capacity can be demarcated by the fire-resistant wall of a first stage gasifier in a first stage gasifier region, and a second stage gasifier can have a second stage gasifier fire-resistant wall that demarcates the second stage gasifier capacity. Protruding fireproof bricks 100 may protrude beyond the usual inner wall face of the first stage fire-resistant wall and farther inside toward the first stage gasifier capacity. A temperature sensor 78 having a temperature sensing tip may be within this protruding fireproof bricks 100 but not completely pass through the protruding fireproof bricks 100.SELECTED DRAWING: Figure 5
【課題】高温及び腐食環境にさらされる熱センサを物理的保護して、温度を正確に測定し、スラグを蓄積せず、その周囲との物理的接触に耐える耐用年数が長い装置を提供する。【解決手段】二段式スラッギングガス化器用の温度測定システムにおいて、第一段ガス化器領域では、第一段ガス化器容積を第一段ガス化器の耐火壁によって画定することができ、第二段ガス化器は、第二段ガス化器容積を画定する第二段ガス化器耐火壁を有することができる。突出耐火煉瓦100は、第一段耐火壁の通常の内側の壁面を越えて突出し、第一段ガス化器容積に向かって中へと突き出てよい。温度検出先端を有する温度センサ78はこの突出耐火煉瓦100の内部にあってよいが、突出耐火煉瓦100を完全には通り抜けない。【選択図】図5 |
