Description
【発明の詳細な説明】 廃棄物を焼却する方法および装置 本発明は少なくとも1個のバーナーを有する化石燃料用焼却装置で廃棄物を焼却 する方法および装置に関する。[Detailed description of the invention] Method and device for incinerating waste The present invention incinerates waste in a fossil fuel incinerator having at least one burner. The present invention relates to a method and apparatus for doing so.
今日近代的廃棄物利用装置では用途分別により極めて大量に発熱量豊富な廃棄物 が得られる。In today's modern waste utilization equipment, extremely large amounts of waste with a high calorific value are separated by use. is obtained.
従来の焼却装置でこの廃棄物を単に焼却する場合には十分公知の腐食問題を考慮 に入れなければならない。Simply incinerating this waste in conventional incinerators takes into account the well-known corrosion problems. must be put in.
また、該廃棄物が塩素化合物を含んでいる場合には、有毒なダイオキシンおよび フランの生成を排除することができない。In addition, if the waste contains chlorine compounds, toxic dioxins and The generation of furan cannot be ruled out.
従って本発明の課題は、高い燃焼効率でかつ有毒物質、特にダイオキシンおよび フランの生成を十分に避ける、廃棄物の焼却方法を開発することである。Therefore, the object of the present invention is to achieve high combustion efficiency and to reduce toxic substances, especially dioxins, and The objective is to develop a waste incineration method that sufficiently avoids the production of furan.
前記課題は本発明の提案により、該廃棄物を化石燃゛料に対し所与の量比でバー ナーの火炎の中心に導入し、そこで焼却することによって解消される。The above-mentioned problem can be solved by the proposal of the present invention, in which the waste is converted into a fossil fuel in a given amount ratio. It can be removed by introducing it into the center of a ner's flame and incinerating it there.
本発明によれば粉砕した固形、または液状またはガス状の廃棄物単独でもまたは 一緒であっても使用することができる。According to the invention, the crushed solid, liquid or gaseous waste alone or They can even be used together.
廃棄物がバーナーの炎の中心で燃焼する際に生じる煙道ガスは本発明の方法に基 づき化石燃料の熱い火炎覆いの外側を突き抜け、その際生成した7ランおよびダ イオキシンが再び無害な化合物に分解される温度に加熱される。同時に発生した 煙道ガス流の緊密な混合が行われ、それによって内部的廃棄物燃焼の煙道ガス中 の腐食性成分は著しく薄ま9、従ってその作用、例えば炉壁に対する作用はかな )制限される。化石燃料としては石炭、油、またはガスも使用することができる 。The flue gas produced when the waste is combusted in the center of the burner flame is based on the method of the invention. It penetrates the outside of the hot fossil fuel flame envelope, and the 7 runs and da The ioxin is heated to a temperature at which it decomposes again into harmless compounds. occurred at the same time An intimate mixing of the flue gas stream takes place, thereby reducing the internal waste combustion in the flue gas. The corrosive components of ) limited. Coal, oil, or gas can also be used as fossil fuels .
固形の廃棄物の搬送は有利には空圧、主として空気で行う。部分的にイオン化し た、または不活性化したガスを使用することは特定の用途に対しては有利である 。選別および供給装置でのガス化、溶融および事前燃焼を避けるためには搬送媒 はできるだけ低温で供給すべきである。The solid waste is preferably conveyed pneumatically, primarily by air. partially ionized The use of deactivated or inert gases may be advantageous for certain applications. . Carrier medium to avoid gasification, melting and pre-combustion in sorting and feeding equipment should be supplied as cold as possible.
廃棄物ならびに必要な場合はその搬送媒の導入量を連続的に制御するためには、 発熱量、煙導ガス組成、灰分組成等その他のような特性データを、コンピュータ ーに入力し、連続的目標値/実測値比較の枠内で評価することができる。In order to continuously control the introduction of waste and, if necessary, its carrier medium, Characteristic data such as calorific value, flue gas composition, ash composition, etc. can be evaluated within the framework of a continuous target value/actual value comparison.
多くのバーナーを使用する場合に廃棄物の量を均一に配分し、制限することを行 うためには各バーナーを個々に制御してもよい。Evenly distribute and limit the amount of waste when using many burners. Each burner may be individually controlled to achieve this.
廃棄物に対する燃料の比率は廃棄物の燃焼時間が燃料の時間よシも少いように制 御するのが有利である。The ratio of fuel to waste is controlled so that the burning time of waste is less than the time of fuel. It is advantageous to control it.
それによって該廃棄物はバーナー火炎の中心ですでに燃えつきて、火炎覆いの外 側を通過する煙道ガスは可燃性成分をもはや含んでいないことを確保することが できる。As a result, the waste is already burned out in the center of the burner flame and outside the flame cover. It is possible to ensure that the flue gases passing through the side no longer contain flammable components. can.
石炭火力発電ボイラで本発明による方法によシ廃棄物の同時共焚きの場合でも廃 ガスおよび灰分中の有害物質量は同じ熱出力の場合には石炭のみの燃焼の場合よ シも高くないということが期待される。Even when waste is simultaneously burned in a coal-fired power generation boiler using the method of the present invention, waste can be reduced. The amount of harmful substances in gas and ash is lower than that in coal-only combustion for the same heat output. It is expected that the cost will not be high either.
本発明を図に示した実施例に基づき詳細に説明する。The present invention will be explained in detail based on embodiments shown in the drawings.
固形廃棄物はホッパー1から配分コンベヤー2を介して粉砕装置3に搬送される 。該粉砕装置3の前で送風器4は搬送媒を導入する。該廃棄物/空気混合物は搬 送装置5を介して廃棄物バーナー6に供給され、これはこの例ではバーナー8の 中心に配置されている。The solid waste is conveyed from the hopper 1 via the distribution conveyor 2 to the crushing device 3 . In front of the grinding device 3, a blower 4 introduces a carrier medium. The waste/air mixture is It is fed via a feeder 5 to a waste burner 6, which in this example is connected to a burner 8. centrally located.
また導管9を介して、これも付加的ではあるが、液状またはガス状の廃棄物が燃 焼される。Via conduit 9, liquid or gaseous waste can also be incinerated, although this is also additional. Burned.
導管7は固形の化石燃料を搬送媒および/または液状またはガス状の燃料と共に バーナー8に供給する。Conduit 7 carries the solid fossil fuel together with a carrier medium and/or liquid or gaseous fuel. Supply to burner 8.
コンピュタ−11a、bは例えば分析(燃料、廃棄物、全排ガス、灰分)および 熱的出力(全体、燃料、廃棄物)のような工程データを評価し、制御器12を介 して燃料の量および制御器13を介して廃棄物量を、廃棄物の完全燃焼が燃料の 火炎の中心で常に確保されるように制御する。Computers 11a, b are used for analysis (fuel, waste, total exhaust gas, ash) and Process data such as thermal power (overall, fuel, waste) is evaluated and communicated via controller 12. The amount of fuel and the amount of waste are controlled through the controller 13 until complete combustion of the waste is achieved. Control so that the center of the flame is always maintained.
