A configuration that includes a blower that supplies air into the pressurized fluidized furnace and an exhaust gas increasing device that increases the amount of exhaust gas generated by combustion, and operates the blower and the exhaust gas increasing device when the pressurized fluidized furnace is started up. By doing so, the capacity of exhaust gas discharged can be increased, and the turbine can be driven without reducing the turbine efficiency even if the blower is downsized. As a result, it is possible to reduce the manufacturing cost and the running cost by realizing the downsizing of the blower. Further, by reducing the size of the blower, it is possible to raise the temperature under the condition that the surging of the compressor that generates compressed air to be supplied into the pressurized fluidized furnace is difficult to occur, and the control margin of the pressurized fluidized incineration facility can be increased.
Further, the capacity of the exhaust gas can be increased by connecting the exhaust gas increasing device to the pressurized flow furnace and / or the exhaust gas flow channel on the pressurized fluid furnace side of the turbine. As the exhaust gas increasing device, one or more devices selected from a spraying device, a steam supply device or an air compressor can be suitably used. By supplying at least one of water, steam, or compressed air sprayed to a high-temperature pressurized flow furnace, the capacity of exhaust gas discharged from the furnace can be increased efficiently.
When the pressurized fluidized furnace is started up, air is supplied into the pressurized fluidized furnace by a blower, and at least one of sprayed moisture, steam, or compressed air is supplied to the exhaust gas generated by combustion. Thus, according to the start-up method for increasing the amount of exhaust gas, it is possible to reduce the size of the blower in the pressurized fluidized incineration facility and to reduce the manufacturing cost and the running cost.

本発明によれば、起動用ブロアを小型化して製造コストやランニングコストを低減させると共に、加圧流動炉内に供給する圧縮空気を生成するコンプレッサのサージングを避けることができる等の利点がもたらされる。 According to the present invention, the starter blower can be reduced in size to reduce the manufacturing cost and running cost, and the advantage that the surging of the compressor that generates the compressed air to be supplied into the pressurized fluidized furnace can be avoided. .

以下、本発明の実施の形態を説明する。
本発明に係る加圧流動焼却装置は、被処理物Ｐを燃焼させる加圧流動炉１と、この燃焼により発生した排ガスＧによって駆動されるタービン２及びこのタービン２によって駆動され、加圧流動炉１内に供給する圧縮空気Ａを生成するコンプレッサ３を有する過給機１１を備えている。 Embodiments of the present invention will be described below.
The pressurized fluidized incinerator according to the present invention includes a pressurized fluidized furnace 1 that combusts the workpiece P, a turbine 2 that is driven by the exhaust gas G generated by the combustion, and the turbine 2 that is driven by the turbine 2. 1 is provided with a supercharger 11 having a compressor 3 for generating compressed air A to be supplied to the inside.

加圧流動炉１には、バイオマス、都市ゴミや下水汚泥の脱水ケーキ等の被処理物Ｐが供給口（図示せず）から供給されると共に、下部の燃料供給口（図示せず）から燃焼のための燃料が供給されるようになっている。また、圧縮空気Ａが下部の調整弁２１を介して１次空気用として炉内に吹き込まれ、その残部が上部の調整弁２２を介して２次空気用として吹込まれるようになっており、圧縮空気Ａの充填により、加圧流動炉１内は、加圧されるようになっている。この加圧下で、被処理物Ｐが投入されると、吹き上げられる圧縮空気Ａに起因して高速で流動する砂などの流動媒体によって激しく混合・攪拌され、被処理物Ｐは焼却されるものである。なお、調整弁２１と調整弁２２により加圧流動炉１内に供給する圧縮空気Ａの量が調節されている。   The pressurized fluidized furnace 1 is supplied with a workpiece P such as biomass, municipal waste or sewage sludge dehydrated cake through a supply port (not shown) and burns from a lower fuel supply port (not shown). The fuel for is to be supplied. Compressed air A is blown into the furnace for primary air through the lower adjustment valve 21, and the remainder is blown in for secondary air through the upper adjustment valve 22. By filling with the compressed air A, the pressurized fluidized furnace 1 is pressurized. When the workpiece P is introduced under this pressure, it is vigorously mixed and stirred by a fluid medium such as sand that flows at high speed due to the compressed air A blown up, and the workpiece P is incinerated. is there. The amount of compressed air A supplied into the pressurized fluidized furnace 1 is adjusted by the adjusting valve 21 and the adjusting valve 22.

加圧流動炉１では被処理物Ｐは加圧下で燃焼され、この燃焼により発生した排ガスＧを駆動ガスとしてタービン２を駆動させるようになっている。タービン２には、コンプレッサ３が連結されており、タービン２の駆動にともなって、駆動されるようになっており、コンプレッサ３には空気が供給されるようになっている。そして、このタービン２によって駆動されたコンプレッサ３の駆動によって生成された圧縮空気Ａは、排ガス流路３３の途中に設けた熱交換器からなる空気予熱器５に送られる。この空気予熱器５において、圧縮空気Ａは予熱され、高温・高圧の圧縮空気（燃焼用空気）Ａとして空気供給路３１から調整弁２１と調整弁２２とに分岐する供給路に送られる。このようにして加圧流動炉１内には、コンプレッサ３によって加圧された高圧の圧縮空気Ａが供給されるので、炉内では常圧よりも高圧の状態（加圧下）で被処理物Ｐが燃焼されることになる。なお、本実施の形態において、圧縮空気Ａの空気予熱器５への圧送は、空気供給路３２に取付けられた調整弁２４によって制御されている。調整弁２５は加圧流動炉１の運転終了時等の際に、圧縮空気Ａを大気中に排出するための弁である。   In the pressurized fluidized furnace 1, the workpiece P is combusted under pressure, and the turbine 2 is driven using the exhaust gas G generated by this combustion as a driving gas. A compressor 3 is connected to the turbine 2, and is driven as the turbine 2 is driven. Air is supplied to the compressor 3. The compressed air A generated by driving the compressor 3 driven by the turbine 2 is sent to the air preheater 5 including a heat exchanger provided in the middle of the exhaust gas passage 33. In the air preheater 5, the compressed air A is preheated and sent as high-temperature / high-pressure compressed air (combustion air) A to a supply path that branches from the air supply path 31 to the regulating valve 21 and the regulating valve 22. In this way, since the high-pressure compressed air A pressurized by the compressor 3 is supplied into the pressurized fluidized furnace 1, the workpiece P is in a state higher than normal pressure (under pressure) in the furnace. Will be burned. In the present embodiment, the compressed air A is pressure-fed to the air preheater 5 by the regulating valve 24 attached to the air supply path 32. The regulating valve 25 is a valve for discharging the compressed air A into the atmosphere when the operation of the pressurized fluidized furnace 1 is finished.

加圧流動炉１内は高圧・高温であることから高圧・高温状態のまま排ガスＧが排気される。この排ガスＧは、前述した空気予熱器５で熱エネルギーが回収（熱交換）され、その後、後述する混合室６に送られる。そして、混合室６に送られた排ガスＧは集塵装置７に送られる。この集塵装置７は、排ガスＧ中の煤塵を除去するためのものである。この集塵装置７を設置しないと、排ガスＧ中の煤塵がタービン２に入り込み、タービンを損傷させ又はタービンに付着し、安定した運転を妨げる虞があり、それを防ぐためのものである。   Since the inside of the pressurized fluidized furnace 1 is at high pressure and high temperature, the exhaust gas G is exhausted while maintaining the high pressure and high temperature. This exhaust gas G is recovered (heat exchanged) by the air preheater 5 described above, and then sent to the mixing chamber 6 described later. The exhaust gas G sent to the mixing chamber 6 is sent to the dust collector 7. The dust collector 7 is for removing the dust in the exhaust gas G. If this dust collector 7 is not installed, the dust in the exhaust gas G enters the turbine 2 and damages or adheres to the turbine, which may hinder stable operation, and is intended to prevent this.

集塵装置７において煤塵の除去された清浄ガス（排ガス）Ｇは、駆動ガスとしてタービン２を駆動させ、圧力（膨張）エネルギーが回収される。その後、排ガス流路３３を介して排ガス処理設備８に送られ、排ガス処理設備８に送られた清浄ガス（排ガス）Ｇは煙突９から大気放出されるものである。   The clean gas (exhaust gas) G from which the dust is removed in the dust collector 7 drives the turbine 2 as a drive gas, and the pressure (expansion) energy is recovered. Thereafter, the clean gas (exhaust gas) G sent to the exhaust gas treatment facility 8 via the exhaust gas flow path 33 and sent to the exhaust gas treatment facility 8 is discharged from the chimney 9 to the atmosphere.

加圧流動炉１の立ち上げの際には、調整弁２３を開くと共に、起動用ブロア４を駆動させ、空気を空気供給路３１を介して調整弁２１と調整弁２２から炉内に送る。この空気は、炉内を所定の圧力・温度まで高めるよう、炉内に供給される燃料を燃焼させるために使用され、排出された排ガスＧは排ガス流路３３を通ってタービン２に送られ、このタービン２を徐々に駆動させるようになる。その後、調整弁２３を閉じると共に調整弁２４を開くことによって、起動用ブロア４からの空気をコンプレッサ３の駆動によって生成された圧縮空気Ａに供給を切り替える。この切替に前後して、炉内に供給される燃料を増量して、昇圧・昇温し、定格の圧力と温度にする。なお、起動用ブロア４から供給される圧縮空気Ａは、加圧流動炉１内で加熱されるが、炉外の燃焼器（図示せず）によって加熱してもよい。   When starting up the pressurized fluidized furnace 1, the adjustment valve 23 is opened and the activation blower 4 is driven to send air from the adjustment valve 21 and the adjustment valve 22 into the furnace via the air supply path 31. This air is used to burn the fuel supplied into the furnace so as to raise the inside of the furnace to a predetermined pressure and temperature, and the discharged exhaust gas G is sent to the turbine 2 through the exhaust gas passage 33, The turbine 2 is gradually driven. Thereafter, the adjustment valve 23 is closed and the adjustment valve 24 is opened to switch the supply of the air from the activation blower 4 to the compressed air A generated by driving the compressor 3. Before and after this switching, the amount of fuel supplied to the furnace is increased, and the pressure is increased and the temperature is increased to the rated pressure and temperature. The compressed air A supplied from the starter blower 4 is heated in the pressurized fluidized furnace 1 but may be heated by a combustor (not shown) outside the furnace.

加圧流動炉１には、排ガス増量装置１０に連結される流路３４が接続されている。排ガス増量装置１０は、例えば、水噴霧装置、スチーム供給装置又は空気圧縮機から選択される１以上の装置であり、高温の加圧流動炉に少なくとも噴霧された水分、スチーム又は圧縮空気を供給することにより炉内から排出される排ガスの容量を増加させるものである。排ガス増量装置１０としては、水噴霧装置、スチーム供給装置又は空気圧縮機を適宜組み合わせて用いればよく、例えば、水噴霧装置と空気圧縮機を組み合わせてもよいし、スチーム供給装置と空気圧縮機を組み合わせてもよい。   A flow path 34 connected to the exhaust gas increasing device 10 is connected to the pressurized fluidized furnace 1. The exhaust gas increasing device 10 is one or more devices selected from, for example, a water spray device, a steam supply device, or an air compressor, and supplies at least sprayed moisture, steam, or compressed air to a high-temperature pressurized fluidized furnace. This increases the capacity of the exhaust gas discharged from the furnace. As the exhaust gas increasing device 10, a water spray device, a steam supply device, or an air compressor may be used in appropriate combination. For example, a water spray device and an air compressor may be combined, or a steam supply device and an air compressor may be combined. You may combine.

排ガス増量装置１０としては、これらに限らず様々なものを用いることができるが、水噴霧装置又はスチーム供給装置から供給される噴霧された水分やスチームによって、製造コストやランニングコストを増加させることなく排ガス量を効率よく増加させることができる。   The exhaust gas increasing device 10 is not limited to these, but various devices can be used without increasing the manufacturing cost and running cost due to the sprayed moisture or steam supplied from the water spray device or the steam supply device. The amount of exhaust gas can be increased efficiently.

また、これら排ガス増量装置１０に連結された流路３４は、タービン２よりも加圧流動炉１側の排ガス流路３３途中に設けられたチャンバー又はダクトからなる混合室６にも接続されており、この混合室６で高温の排ガスＧと供給された水分やスチームが混合することにより排ガスの容量がさらに増加されるものである。なお、排ガス増量装置１０は、加圧流動炉１及び混合室６の両方に連結される必要はなく、どちらか一方に連結されていればよい。   Further, the flow path 34 connected to the exhaust gas increasing device 10 is also connected to a mixing chamber 6 including a chamber or a duct provided in the middle of the exhaust gas flow path 33 on the pressurized flow furnace 1 side of the turbine 2. The capacity of the exhaust gas is further increased by mixing the high temperature exhaust gas G with the supplied moisture and steam in the mixing chamber 6. Note that the exhaust gas increasing device 10 does not need to be connected to both the pressurized fluidized furnace 1 and the mixing chamber 6, and may be connected to either one.

上記により、タービン２に送られる排ガスＧの量が増加され、起動用ブロア４を小型化してもタービン効率を落すことなく、タービン２を駆動させることができる。その結果、起動用ブロア４の小型化（例えば、最大静圧で通常４５ｋＰａＧのブロアが必要なところ、３０ｋＰａＧ以下のものを用いることができる。）を実現できることで製造コストやランニングコストを低減させることが可能となる。また、過給機のコンプレッサは、低流量、高圧力比でサージングを起こしやすいが、排ガス増加によりサージングを起こし難い条件で昇温ができ、加圧流動焼却設備の制御の余裕を増すことができる。   As a result, the amount of the exhaust gas G sent to the turbine 2 is increased, and the turbine 2 can be driven without reducing the turbine efficiency even if the startup blower 4 is downsized. As a result, the starter blower 4 can be reduced in size (for example, a blower of 45 kPaG is usually required at the maximum static pressure, but a 30 kPaG or less can be used), thereby reducing manufacturing costs and running costs. Is possible. The turbocharger compressor is prone to surging at a low flow rate and a high pressure ratio, but it can raise the temperature under conditions where surging is difficult to occur due to an increase in exhaust gas, and the control margin of the pressurized fluidized incineration equipment can be increased. .
