description	To maintain furnace pressure at positive pressure and to suppress damage to a damper caused by high temperature.SOLUTION: An in-furnace pressure control system 3 for controlling an internal pressure of a furnace body 1 of a combustion furnace 100 comprises: a pressure sensor 31 which is provided on the furnace main body 1 and detects the internal pressure of the furnace main body 1; a temperature sensor 32 which is provided on an exhaust cylinder 2 connected to the furnace main body 1 and detects a temperature of exhaust gas in the exhaust cylinder 2; air supply means 33 which is provided on the exhaust cylinder 2 upstream of a damper 21 and supplies air into the exhaust cylinder 2; and a control device 34 for controlling an operation of the air supply means 33. The control device 34 controls a flow rate of air from the air supply means 33 so that the pressure detected by the pressure sensor 31 is a positive pressure and that a temperature detected by the temperature sensor 32 is lower than a prescribed value.SELECTED DRAWING: Figure 1 【課題】炉圧を正圧に維持すると共に、高温によるダンパの破損を抑制すること。【解決手段】燃焼炉１００の炉本体１の内部の圧力を制御するための炉内圧力制御システム３は、炉本体１に設けられ、炉本体１の内部の圧力を検出する圧力センサ３１と、炉本体１に接続される排気筒２に設けられ、排気筒２の内部の排気ガスの温度を検出する温度センサ３２と、排気筒２においてダンパ２１よりも上流に設けられ、排気筒２の内部に空気を供給する空気供給手段３３と、空気供給手段３３の動作を制御する制御装置３４と、を備える。制御装置３４は、圧力センサ３１によって検出される圧力が正圧になるように、かつ、温度センサ３２によって検出される温度が所定の値未満になるように、空気供給手段３３からの空気の流量を調節する。【選択図】図１
