Description
本発明は、廃棄物溶融炉処理設備において、廃棄物を溶融処理する廃棄物溶融炉から発生する可燃ガス及び可燃残渣(チャー)を燃焼室で燃焼させ、燃焼後の排ガスで蒸気を発生させて熱回収するボイラの蒸気量の制御に関する。 In the waste melting furnace processing facility, the present invention burns combustible gas and combustible residue (char) generated from a waste melting furnace for melting waste in a combustion chamber, and generates steam from the exhaust gas after combustion. The present invention relates to the control of the steam volume of a boiler that recovers heat.
一般廃棄物、産業廃棄物、シュレッダーダスト等の廃棄物を廃棄物溶融炉で溶融処理する際に発生する可燃ガス及びチャーを含有する排ガスは、廃棄物溶融炉の後段に設置されている燃焼室に導入して燃焼させ、排出される燃焼排ガスはボイラで熱回収が行われる(特許文献1、2参照)。 An exhaust gas containing combustible gas and char generated when general waste, industrial waste, shredder dust and other waste are melted in the waste melting furnace is a combustion chamber installed at the rear stage of the waste melting furnace The combustion exhaust gas that is introduced into and combusted and discharged is heat recovered by a boiler (see Patent Documents 1 and 2).
廃棄物溶融炉に投入される廃棄物のごみ質は一定でなく変動するため、廃棄物溶融炉から排出される排ガス中の可燃ガスの成分やチャーの量などが変動する。例えば、自動車シュレッダーダスト(ASR)等のプラスチック含有廃棄物のような粒径が小さくかつプラスチック類が多く急速熱分解が起こりやすい廃棄物が廃棄物溶融炉に投入されて処理される場合、熱分解後の可燃ガス及びチャーが飛散して燃焼室に導入されて急激に燃焼室の温度が上昇する。燃焼室の温度が急上昇すると、燃焼室後段のボイラにおける蒸発量が大きく変動する状況が見られた。 Since the waste quality of the waste introduced into the waste melting furnace is not constant and fluctuates, the combustible gas components and the amount of char in the exhaust gas discharged from the waste melting furnace fluctuate. For example, when waste containing a small particle size, such as waste containing plastic such as automobile shredder dust (ASR), and containing a large amount of plastics, which is susceptible to rapid thermal decomposition, is put into a waste melting furnace and processed. Later combustible gas and char are scattered and introduced into the combustion chamber, and the temperature of the combustion chamber rises rapidly. When the temperature of the combustion chamber rose rapidly, the amount of evaporation in the boiler at the rear stage of the combustion chamber changed greatly.
従来は廃棄物溶融炉から排出する熱分解後の可燃ガス及びチャーが急増し、ボイラ蒸気量が大幅に上昇した際に、オペレータ操作で対応していたため、変動幅が大きすぎて変動に追従できなかった場合はボイラ蒸気温度上限値を超過し、プラント非常停止に至る状況も見られた。 Conventionally, when the pyrolysis combustible gas and char discharged from the waste melting furnace increased rapidly, and the boiler steam volume increased significantly, it was handled by operator operation, so the fluctuation range was too large to follow the fluctuation. If not, the boiler steam temperature upper limit was exceeded, leading to an emergency shutdown of the plant.
そこで、本発明は、廃棄物溶融炉の変動状況から変化が最も速いものを選択して廃棄物溶融炉内の熱分解状況を速やかに検知し、それに応じて羽口への送風空気量を調整することで熱分解後の可燃ガス及びチャーの飛散量をコントロールして蒸気量の変動を抑制する廃棄物溶融炉設備のボイラの蒸気量制御装置を提供するものである。 Therefore, the present invention selects the fastest change from the fluctuation state of the waste melting furnace, quickly detects the thermal decomposition state in the waste melting furnace, and adjusts the amount of air blown to the tuyere accordingly Thus, the present invention provides a steam amount control device for a boiler of a waste melting furnace facility that controls the amount of scattering of combustible gas and char after pyrolysis to suppress variation in the amount of steam.
本発明のボイラの蒸気量制御装置は、炉上部から廃棄物を投入し、炉下部に配設した複数段の羽口から酸素源を供給して、廃棄物中の灰分及び非燃焼物を溶融し、溶融物を炉底部から排出する廃棄物溶融炉と、廃棄物溶融炉で発生する可燃ガス及び可燃残渣を燃焼する燃焼室と、燃焼室で発生した排ガスの顕熱を回収するボイラと、ボイラで顕熱回収後の排ガスの排ガス処理装置と処理後の排ガスを誘引通風機を介して排出する煙突より構成する廃棄物溶融炉設備の蒸気量制御設備において、酸素含有ガス又は酸素富化ガスが吹き込まれる炉底部の下段羽口と、前記下段羽口の上方に配置されるとともに、上下方向において重ならないように前記廃棄物溶融炉の円周方向にずらして配置された空気が吹き込まれる上段羽口及び中段羽口からなる前記複数段の羽口と、前記廃棄物溶融炉に設置した廃棄物溶融炉内の廃棄物の充填レベルを測定する充填レベル測定装置と、前記ボイラに設置したボイラの発生蒸気量を測定する発生蒸気量測定装置と、前記誘引通風機の運転負荷を測定する誘引通風機運転負荷測定装置と、前記煙突の出口の排ガス量を測定する排ガス量測定装置と、前記各測定装置からの測定結果が入力され、これらの測定結果に基づいて上段羽口送風空気量及び中段羽口送風空気量のそれぞれの設定に応じて各流量調整弁の調整量を演算し、前記上段羽口あるいは中段羽口へ送風する送風量を調整する前記各流量調整弁へ弁の開度を調整する制御信号を出力する空気供給制御装置とを備えたことを特徴とする。 The boiler steam amount control apparatus of the present invention is configured to supply waste from the upper part of the furnace and supply an oxygen source from a plurality of tuyeres arranged in the lower part of the furnace to melt ash and non-combustibles in the waste. A waste melting furnace for discharging the melt from the bottom of the furnace, a combustion chamber for burning the combustible gas and the combustible residue generated in the waste melting furnace, a boiler for recovering sensible heat of the exhaust gas generated in the combustion chamber, Oxygen-containing gas or oxygen-enriched gas in a steam control equipment of a waste melting furnace facility composed of an exhaust gas treatment device for exhaust gas after sensible heat recovery in a boiler and a chimney that exhausts the treated exhaust gas via an induction fan A lower tuyere at the bottom of the furnace into which the air is blown, and an upper stage into which the air placed while being shifted in the circumferential direction of the waste melting furnace is disposed above the lower tuyere and does not overlap in the vertical direction From tuyere and middle tuyere Generation of measuring the tuyere of the plurality of stages, a filling level measuring device for measuring the filling level of the waste of the waste melting furnace installed waste melting furnace, the generation amount of steam boilers installed in the boiler The measurement results from the steam amount measuring device, the induced ventilator operating load measuring device that measures the operating load of the induction fan, the exhaust gas amount measuring device that measures the exhaust gas amount at the outlet of the chimney, Based on these measurement results , the adjustment amount of each flow rate adjustment valve is calculated according to the respective settings of the upper tuyere blast air amount and the middle tier tuyere air amount, to the upper tuyeres or the middle tuyeres characterized by comprising an air supply controller for outputting a control signal, wherein adjusting the opening degree of the valve to the flow rate adjustment valve for adjusting the air volume to be blown.
本発明は、熱分解が急速に進むと、ごみレベルの急低下、ボイラ蒸気量の急増、誘引通風機の運転負荷の急増、排ガス流量の急増があるため、廃棄物溶融炉内の廃棄物の充填レベル、ボイラの発生蒸気量、誘引通風機の負荷および煙突出口の排ガス量を測定し、これらの検出端の測定値に基づいて溶融炉内の熱分解状況を早期に検知して送風空気量を自動的に調整することで、ボイラ蒸気量の変動が大きくなる前の時点での調整が可能となり、ボイラ蒸気量を適正範囲内に維持管理することが可能となる。また、廃棄物溶融炉の安定溶融状況を維持できる送風量バランスを保ちながら送風流量調節して確実にボイラ蒸気量の変動の抑制が可能となる。 In the present invention, when pyrolysis progresses rapidly, there is a sudden decrease in the dust level, a rapid increase in the boiler steam volume, a sudden increase in the operating load of the induction fan, and a rapid increase in the exhaust gas flow rate. Measure the filling level, the amount of steam generated by the boiler, the load of the induction fan and the amount of exhaust gas from the smoke outlet, and detect the pyrolysis status in the melting furnace at an early stage based on the measured values at these detection ends , and the amount of blown air By adjusting automatically, it becomes possible to make adjustment before the boiler steam amount fluctuates greatly, and it becomes possible to maintain and manage the boiler steam amount within an appropriate range. Further, it is possible to reliably suppress fluctuations in the amount of boiler steam by adjusting the air flow rate while maintaining the air flow rate balance capable of maintaining the stable melting state of the waste melting furnace.

(1)ごみレベルの急低下、(2)ボイラ蒸気量の急増、(3)誘引通風機の運転負荷の急増、あるいは(4)排ガス流量の急増のいずれかの時には、溶融炉内の熱分解が急速に進んでいるため、いずれかの検出信号が空気供給制御装置に入力されると、上段羽口あるいは中段羽口の流量調整弁を調整して送風空気量を減らして熱分解を速やかに抑える。この抑制により、ボイラ蒸気量の変動幅が大きくなることはなく、確実にボイラ蒸気量の変動を抑制できるようになった。 Thermal decomposition in the melting furnace occurs when either (1) a sharp drop in dust level, (2) a rapid increase in boiler steam volume, (3) a sudden increase in operating load of the induction fan, or (4) a sudden increase in exhaust gas flow rate Therefore, when any detection signal is input to the air supply control device, the flow adjustment valve at the upper tuyere or the middle tuyere is adjusted to reduce the amount of blown air and to quickly perform thermal decomposition. suppress. By this suppression, the fluctuation range of the boiler steam amount is not increased, and the fluctuation of the boiler steam amount can be surely suppressed.
