しかし、鉱物性燃料を熱源とする場合、運転操作は安全と簡便性はあるが、避けられない問題の、CO排出による環境汚染及び燃費の高額負担が解決できないため、鉱物性燃料以外の燃料を求めた。しかしながら、加温装置で水を加温し常時蒸気化し、或いは温水若しくは温風の発生源となる燃焼炉内部温度を安定させ、継続完全燃焼させるための工夫を繰り返し試みたが困難を極め、特にオガ粉、木材、同系チップ材及び同炭化材等々は、100%の燃焼ができず時間経過とともにその燃焼効果は激減してしまい、やがて燃焼炉内部にスケ−ルが付着し、燃焼時にスラッジが発生し燃焼が中断してしまった。However, when mineral fuel is used as the heat source, the operation is safe and simple. However, the environmental pollution caused by CO 2 emissions and the high cost of fuel consumption cannot be solved. Asked. However, repeated attempts have been made to repeatedly heat the water with a heating device to constantly vaporize it, or to stabilize the internal temperature of the combustion furnace, which is the source of hot water or hot air, and to continuously burn it. Oga powder, wood, similar chip materials, carbonized materials, etc. are not 100% combustible, and the combustion effect decreases drastically over time, and eventually the scale adheres to the inside of the combustion furnace, and sludge is generated during combustion. Occurred and combustion was interrupted.

なお、一般的に有機材料が燃焼した場合、燃料となる材の含水率及び土等の不純物の影響を受け、炉内部にスケ−ルの発生及びスラッジが発生し燃焼を妨げる。その残渣排除は連続燃焼途中では不可能で、その発生を防ぐ手段の解決が出来ず、連続運転中に燃焼炉内部の残渣処理は困難を極め解決手段もなく、有機物燃焼ボイラの完成に至らず業界では多くが中途で断念し今日に至った。燃焼炉は、酸素供給できるものの、燃焼炉内部の温度が高温のためその装置の破損も激しく、燃焼促進備品の設置も困難をきたし、燃料のオガ粉、木材、同質系チップ材及び同炭化材の炭粉材を連続完全燃焼させ、連続して最大カロリ−を引き出すための工夫が難しく、燃焼炉内にスラッジの発生ならびにスケ−ルの付着及びスラッジを含む木灰等残渣を燃焼炉から排出処理に欠点があり、これらを解決する決定的条件を見つけ出せなかった。  In general, when an organic material burns, it is affected by the moisture content of the material used as fuel and impurities such as soil, generating scale and sludge inside the furnace, preventing combustion. Residue elimination is not possible during continuous combustion, and it is not possible to solve the means to prevent it from occurring. Residue treatment inside the combustion furnace during continuous operation is extremely difficult and there is no solution, and the organic combustion boiler is not completed. Many in the industry abandoned and reached today. Although the combustion furnace can supply oxygen, the internal temperature of the combustion furnace is high, so the equipment is severely damaged, and it is difficult to install combustion-promoting equipment. Fuel sawdust, wood, homogeneous chips and carbonized materials It is difficult to devise a method to continuously burn the charcoal powder material and continuously extract the maximum calorie. The sludge is generated in the combustion furnace, the scale adheres and the wood ash residue including the sludge is discharged from the combustion furnace. Have drawbacks, and we have not been able to find a decisive condition to solve them.

課題が解決しようとする課題The problem that the problem is trying to solve

本発明は、このような従来の問題点並びに鉱物性燃料によるCOの削減及び燃料費の削減を図るため特に鉱物性燃料を排除し、バイオマス燃料の完全燃焼させ、生ゴミ炭化材並びに建築廃材等及び農産物廃棄物を応用し燃料となり、煤煙、悪臭の排出をなくし、ボイラ装置の安全性の確保並びにダイオキシン及びCOの削減を図り自然環境保護に役立ち、燃料費の削減ができ、これからの農業の温室栽培等にも好まれて広く普及でき、バイオマス燃料専用エコボイラの場合、処分対象の残渣である灰も酸性土壌の中和剤及び益肥としてリサイクル使用でき、廃棄物処理の心配もなく安全で安心して使い易いボイラを提供する。In order to reduce the CO 2 and the fuel cost due to such conventional problems and the mineral fuel, the present invention eliminates the mineral fuel in particular, completely burns the biomass fuel, and produces the garbage carbonized material and the building waste material. becomes like and fuel applying agricultural waste, soot, eliminates the discharge of malodorous helps ensure safety and environmental protection work to reduce dioxin and CO 2 of the boiler unit, it can reduce fuel costs, the future It is also popular for agricultural greenhouse cultivation and can be widely used. In the case of an eco-boiler dedicated to biomass fuel, ash, which is the residue to be disposed of, can be recycled as a neutralizing agent and fertilizer for acidic soil, and there is no worry about waste disposal. Provide a safe, secure and easy-to-use boiler.

課題を解決するための手段Means for solving the problem

解決しようとする問題点は、燃焼効果を上げ如何なる燃料も完全燃焼させることにあり、初期燃焼は補助燃料に、エタノ−ル及び食用廃油を燃料に用いた補助バ−ナ−により、燃料に点火し高温で連続完全燃焼できる自動制御式ボイラ装置で、バイオマス燃料の木材、同質系チップ材並びに同炭化材及び有機物、同炭化材を主燃料とし、角材以外の燃料をそれぞれの保存タンクに保存し、自動制御によりホッパ−で受け、スクリュ−コンベア−により燃焼炉へ直接供給する自動制御装置からなり、火吹き竹原理により強制給気を行う完全燃焼ボイラである。このため、COの削減及び燃料費削減の蒸気利用ボイラ並びに温水ボイラで、センサ−付き自制御式蒸気並びに温水循環装置及び放熱器と、殺菌等の蒸気直接利用を目的とし、従来の課題が解決できた。The problem to be solved is to increase the combustion effect and completely burn any fuel. In the initial combustion, the fuel is ignited by an auxiliary burner using ethanol and edible waste oil as fuel. This is an automatic control boiler that can burn continuously and completely at high temperatures. It uses biomass wood, homogenous chip material, carbonized material and organic matter, and carbonized material as the main fuel, and fuels other than slabs are stored in their storage tanks. This is a complete combustion boiler that consists of an automatic control device that is received by a hopper by automatic control and is directly supplied to a combustion furnace by a screw conveyor, and performs forced air supply by the fire-blown bamboo principle. For this reason, conventional steam steam generators and hot water boilers that reduce CO 2 and reduce fuel costs are intended for direct use of steam such as sterilization, as well as self-controlled steam with sensors and hot water circulation devices and radiators. It was solved.

発明の効果The invention's effect

なお、燃焼効果を上げ如何なる燃料も完全燃焼させることにあり、蒸気発生及び水の加温目的を達成するために、センサ−設置によりバイオマス燃料となる角材、同系チップ材、同炭化材を角材を除き同時にスクリュ−コンベア−により燃焼炉に直接自動供給でき、スラッジの発生をなくすことにあるため、二重燃焼炉内部に設置された補助燃焼装置及び炉内部の床面、壁面に設置した火吹き竹原理による加圧式強制給気口設置により燃焼温度を一気に上昇させ、排気煙突により吸引し燃焼炉全体で完全燃焼させることで、燃焼炉内部の温度を700℃〜800℃に継続し保ち、スケ−ルの付着及びスラッジの発生が防止でき、蒸気及び温水を連続して発生させることを手段とし、これらに加え全てを自動制御方式にすることにより解決でき、更に、排気は有害物質が含まれないことから、排気筒にサイクロン装置を設置することにより温熱2次利用を行う温風吹き出し口が設置できる構造を具備した多種類及び多用途のバイオマス燃料専用エコボイラの製造を可能とした。  In addition, in order to increase the combustion effect and completely burn any fuel, in order to achieve the purpose of steam generation and water heating, square wood, similar chip material, and carbonized material that become biomass fuel by installing sensors are used. At the same time, it can be automatically supplied directly to the combustion furnace by a screw conveyor and eliminates the generation of sludge, so the auxiliary combustion device installed inside the double combustion furnace and the fire-blown bamboo principle installed on the floor and walls inside the furnace The combustion temperature is increased at a stroke by installing a pressurized forced air inlet by means of suction, sucked by the exhaust chimney, and completely burned in the entire combustion furnace, so that the temperature inside the combustion furnace is continuously maintained at 700 ° C to 800 ° C. Adherence and sludge generation can be prevented, and it is possible to solve this problem by using steam and hot water continuously as a means, and in addition to these automatic control systems. In addition, since the exhaust does not contain harmful substances, it is equipped with a structure that can install a hot air outlet for secondary use of heat by installing a cyclone device in the exhaust stack, and a multi-type and versatile biomass fuel dedicated eco-boiler Made possible.

しかしながら、燃焼時に燃焼効果を最も上げ熱量を最大限確保するためバイオマス燃料の含水率は30%程度を好み、同炭化材燃料の含水率は15%程度を好み水分中の酸素を取り込んで良好な燃焼を継続し、高カロリ−エネルギ−を発生することが出来る。ところが、含水率は前記を超えることもあるが、燃焼を続けることにより燃焼炉内部の温度が高まり安定し、燃焼炉内部の温度が著しく低下することはない。混入された不良燃料の供給を受けた燃焼炉は、そのとき、燃焼炉内部の温度は一時的に300℃〜500℃程度に低下することもあり、燃焼炉内部温度が低下した場合、瞬時にして自動制御による補助燃焼バ−ナ−の作動及び火吹き竹原理による強制給気の働きにより高温で継続燃焼が始まり、自動的に燃焼炉の温度は上昇し700℃〜800℃で、連続完全燃焼させボイラの熱効率を上げることができた。  However, in order to maximize the combustion effect during combustion and to ensure the maximum amount of heat, the biomass fuel has a moisture content of about 30%, and the carbonized fuel has a moisture content of about 15%. Combustion can be continued and high calorie energy can be generated. However, although the moisture content may exceed the above, by continuing combustion, the temperature inside the combustion furnace increases and becomes stable, and the temperature inside the combustion furnace does not drop significantly. In the combustion furnace that has received the supply of the mixed defective fuel, the temperature inside the combustion furnace may temporarily drop to about 300 ° C. to 500 ° C. When the temperature inside the combustion furnace drops, The continuous combustion starts at a high temperature by the operation of the auxiliary combustion burner by automatic control and the forced air supply by the fire-blown bamboo principle, and the temperature of the combustion furnace automatically rises to 700 ° C to 800 ° C for continuous complete combustion. The thermal efficiency of the boiler could be increased.

以上、発明したバイオマス燃料専用エコボイラによれば、請求項1記載の発明では鉱物性燃料の排除により、COが削減でき燃料費の削減を図ることができる自動制御による燃料供給方式により、現代社会で最も要求される条件について最大限効果をもたらし、幅広く活用でき、一般的に好まれ広く普及し易いものとなる。As described above, according to the invented exclusive eco-boiler for biomass fuel, in the invention according to claim 1, by eliminating the mineral fuel, CO 2 can be reduced and the fuel cost can be reduced. The most demanding conditions are most effective, can be used widely, and are generally preferred and widely spread.

図1は、本発明装置によりバイオマス燃料及び同炭化材を、それぞれの保存タンクに保存される。タンクに保存された燃料は、自動制御を受けホッパ−に移動する。ホッパ−に入った燃料は、燃焼炉に直接供給するにあたり、燃焼炉内センサ−及びインバ−タ−を連結させ、スクリュ−の回転を変動させ、燃料を自動供給し熱量の増減を計ることができ、木質系チップ材、同炭化材は、自由に混合しそれぞれを補給できる。燃料供給路は、燃焼炉内部の高熱が進入しないため、サイクロン熱遮蔽板が設置され、燃料供給路上部には水冷式燃料定量供給装置により更に熱を遮断している。しかしながら、燃料供給路に高温異常が発生し燃料に点火するような場合、異常感知センサ−により警報装置器が作動し、自動で燃料供給が停止され、燃料に引火しないよう水冷式燃料定量装置による燃料供給並びに熱交換器及び温熱利用、同リタ−ン水の実施方法を示した全体図である。  In FIG. 1, the biomass fuel and the carbonized material are stored in the respective storage tanks by the apparatus of the present invention. The fuel stored in the tank is automatically controlled and moved to the hopper. When the fuel entered the hopper is directly supplied to the combustion furnace, the sensor in the combustion furnace and the inverter are connected, the rotation of the screw is changed, the fuel is automatically supplied, and the amount of heat can be increased or decreased. The wood-based chip material and the carbonized material can be freely mixed and replenished. Since high heat inside the combustion furnace does not enter the fuel supply path, a cyclone heat shielding plate is installed, and heat is further cut off at the upper part of the fuel supply path by a water-cooled fuel quantitative supply device. However, when a high temperature abnormality occurs in the fuel supply path and the fuel is ignited, the alarm device is activated by the abnormality detection sensor, the fuel supply is automatically stopped, and the water-cooled fuel metering device is used so that the fuel is not ignited. It is the whole figure which showed the fuel supply, the heat exchanger, utilization of heat, and the implementation method of the return water.

本発明の実施例2は、ボイラ燃焼炉の断面構造は、鉄部給気槽及びキャスタ−部の二重構造からなり、断面構造は二層で構成され、下部に残渣処理装置があり残渣排除用の残渣排除溝及びスクリュ−コンベア−を設置し、燃焼床面部及び燃焼炉壁面部が二重構造になり、空気層が設けられ、火吹き竹方式の強制給気口を設け、上部に熱交換器が設置され、熱交換器排気部にサイクロン熱遮蔽装置を用いた排気煙突口を備える。炉内キャスタ−部に設置された熱気流通路及び熱対流による気流発生部に分かれ、熱交換器の下部及に水溜り釜を設け、図7による下部釜及び上部釜の中間に熱交換用水管を縦に設置し、上方部に蒸気溜まり及び温水溜まり釜を設け自動制御により送りだされる。
ボイラ外部からの水導入管管路及び蒸気及び温水のリタ−ン管路に磁気式水処理装置を配備し、配管管路内部の防錆およびスケ−リング防除のため、市販の磁気式水処理装置を具備する。
In the second embodiment of the present invention, the cross-sectional structure of the boiler combustion furnace is a double structure of an iron part air supply tank and a caster part, the cross-sectional structure is composed of two layers, and there is a residue treatment device at the lower part to eliminate residues. Residue removal groove and screw conveyor are installed, the combustion floor surface and the combustion furnace wall surface have a double structure, an air layer is provided, a fire-blown bamboo type forced air inlet is provided, and a heat exchanger at the top And an exhaust chimney using a cyclone heat shield device is provided in the heat exchanger exhaust. It is divided into a hot air flow path installed in the caster part in the furnace and an air flow generating part by heat convection, and a water reservoir is provided in the lower part of the heat exchanger and a water pipe for heat exchange in the middle of the lower and upper kettles in FIG. Is installed vertically, and a steam reservoir and a hot water reservoir are provided in the upper part, and are sent out by automatic control.
A magnetic water treatment device is installed in the water introduction pipe line from the outside of the boiler and the steam and warm water return pipe line, and a commercially available magnetic water treatment system is used for rust prevention and scaling control inside the pipe line. Device.

本発明の実施例1及び2を完全に満足させる。しかしながら、炉内部には自動制御により、エタノ−ル及び食用廃油を燃料とした点火バ−ナ−で捕助燃焼を行ない、火吹き竹原理の強制給気を受けることができ完全燃焼する。
循環管路内は、更に念を入れ錆処理及びスケ−ル除去処理のメンテナンス用に、管路内検査用テレビカメラ並びに高圧洗浄用ノズルの侵入口50A及び排除物排出口及びドレンコック50A以上を非常時対応用にSUS材を用いた配管を具備する。
Examples 1 and 2 of the present invention are fully satisfied. However, inside the furnace, by automatic control, trapping combustion is performed by an ignition burner using ethanol and edible waste oil as fuel, and forced combustion of the fire-blown bamboo principle can be received and complete combustion is achieved.
For the maintenance of the rust treatment and scale removal treatment, the inside of the circulation pipeline is equipped with a TV camera for in-pipe inspection, an entry port 50A for a high-pressure washing nozzle, an exhaust outlet, and a drain cock 50A or more. A pipe using SUS material is provided for emergency.

そこで、エネルギ−として放熱利用し温度が低下した蒸気及び温水はリタ−ンし、ボイラ側面の温水一時保存タンクに保存し、効率よく短時間に加温でき水の温度を一定化させ効率を上げる。配管系等は、修理に必用とする止水用ボ−ルバルブ及び温水を移動させるための脱着可能なラインポンプ及び放熱器からなる。  Therefore, steam and hot water whose temperature has been reduced by using heat dissipation as energy is returned and stored in a temporary hot water storage tank on the side of the boiler, which can be heated efficiently and in a short time to stabilize the temperature of the water and increase the efficiency. . The piping system and the like includes a water stop ball valve necessary for repair, a removable line pump for moving hot water, and a radiator.

本発明によるボイラの始動は、操作盤の作動スイッチをONにすることで、自動的に点火し燃焼が開始される。そのとき燃料供給自動制御装置が作動し、ホッパ−から供給される。外部から搬入されたバイオマス燃料を保存ホッパ−から図1、図3、図4によるスクリュ−コンベア−により図2のボイラ燃焼炉に直に送り込み、図1の点火バ−ナ−により効果的に高温で燃焼させる。そこで、蒸気と加温された温水が制御装置の設定温度に到達することにより、自動的にラインポンプが作動し、蒸気利用及び暖房利用目的の温水が循環し放熱器により放熱され、放熱が終わった蒸気又は温水がリタ−ンし、図1の温水リタ−ンタンクに入り込み、また、加温され繰り返えし送り出される。  The boiler according to the present invention is started by automatically igniting and starting combustion by turning on the operation switch of the operation panel. At that time, the automatic fuel supply control device operates and is supplied from the hopper. The biomass fuel carried in from the outside is sent directly from the storage hopper to the boiler combustion furnace shown in FIG. 2 by the screw conveyor shown in FIGS. 1, 3, and 4, and is effectively heated by the ignition burner shown in FIG. Burn with. Therefore, when the steam and heated hot water reach the set temperature of the control device, the line pump automatically operates, the hot water for steam use and heating use is circulated and dissipated by the radiator, and the heat dissipation ends. Steam or hot water is returned to the hot water return tank shown in FIG. 1, and is heated and repeatedly sent out.

このような、前記バイオマス燃料系チップ材燃料及び同炭化材燃料による本発明のバイオマス燃料専用エコボイラの、図示を省略したバイオマス燃料専用点火バ−ナ−及び強制給気により不完全燃焼による不備を防止し、完全燃焼による連続運転を継続させ安定した蒸気または温水を供給する。  The above-described biomass fuel-dedicated eco-boiler of the present invention using the biomass fuel chip material fuel and the same carbonized material fuel prevents incomplete combustion due to incomplete combustion by a biomass fuel dedicated ignition burner and forced air supply (not shown). Then, the continuous operation by complete combustion is continued to supply stable steam or hot water.

図3は、燃焼し木灰となった残渣を、自動制御により排除される灰が排除溝に落下する働きにより燃焼炉から排出し、更にスクリュ−コンベア−によってボイラ本体から外部に放出される。残渣木灰は、リサイクルに用いられ酸性土壌の中和剤及び益肥としても役立ち産業廃棄物は排出されない。  In FIG. 3, the residue that is burned and becomes wood ash is discharged from the combustion furnace by the action of the ash removed by automatic control falling into the removal groove, and further discharged from the boiler body to the outside by the screw conveyor. Residual wood ash is used for recycling and serves as a neutralizer and fertilizer for acidic soil, and no industrial waste is discharged.

炉内部の温度上昇により、図9は、上段の釜内部に設置されている蒸気及び温水溜まりの水タンク並びに縦に配置した水管50A及び最上部に設置された蒸気及び温水溜まりに、温水が蒸気となり、蒸気は加圧蒸気となり送られ、温水は循環ラインポンプで送り出され、放熱器により放熱させ温熱をそれぞれの用途の利用に供する。  Due to the temperature rise inside the furnace, FIG. 9 shows that the hot water is steamed into the steam and hot water pool water tank installed in the upper kettle, the vertically arranged water pipe 50A, and the steam and hot water pool installed at the top. Then, the steam is sent as pressurized steam, and the hot water is sent out by a circulation line pump, and the heat is dissipated by a radiator to use the heat for each use.

燃焼炉を休止するための消火手段は、操作盤のスイッチをOFにすることで、給気及び燃料の供給が止まり自動停止し鎮火する。鎮火した後の次回の点火は残渣があっても通常に点火作動でき自動運転できる。  The fire extinguishing means for stopping the combustion furnace sets the switch on the operation panel to OF, so that the supply of air and fuel is stopped and the fire is automatically stopped and extinguished. The next ignition after extinguishing the fire can be ignited normally and automatic operation is possible even if there is residue.

本発明のバイオマス燃料専用エコボイラは、岩綿材を用いて缶体を保護及び保温し、外部化粧は焼付け塗装を施した鉄板を用いてラッキング仕上げした。容姿は四角形と丸縦型合成ボイラ若しくは化粧なしのシルバ−コ−ト塗装仕上げによる。  In the eco-boiler for biomass fuel of the present invention, the can body was protected and kept warm using rock wool, and the external makeup was racked using an iron plate that was baked. Appearance is a square and round vertical synthetic boiler or a silver coat finish without makeup.

又、請求項2では、燃料供給をスクリュ−コンベア−により自動供給し、バイオマス燃料及び同炭化材燃料の含水分30%程度は、強制的に酸素供給をすることで燃焼効果を上げ火力を増し完全燃焼させ、カロリ−を高めるメリットが生ずる。本ボイラの点火及び消火は自動制御装置によるもので、スイッチをONにすることで効果的に作動し、すべて自動制御方式による人件費の削減を計ることができ、燃焼に不備が生じた場合、遠隔操作可能な状態で、警報と共に赤色灯が回転表示し警報装置が作動し自動停止する。  Further, in claim 2, the fuel supply is automatically supplied by a screw conveyor, and the moisture content of biomass fuel and the carbonized fuel of about 30% is forcibly supplied with oxygen to increase the combustion effect and increase the thermal power. There is an advantage that calories are increased by complete combustion. Ignition and fire extinguishing of this boiler is based on an automatic control device, it works effectively by turning on the switch, and all can reduce the labor cost by the automatic control method. In a state where remote operation is possible, a red light is rotated and displayed together with an alarm, the alarm device is activated and automatically stops.

さらに、請求項2記載の発明では、バイオマス燃料系チップ材、同炭化材はそれぞれの燃料が燃焼した後に出る残渣である木灰の排除及び燃焼に不備が生じた場合の処置で、温度センサ−が感知し、補助点火バ−ナ−が自動的に点火し燃焼不備の解除を図ることができ、自動制御装置の働きにより効果的に連続燃焼させる。  Furthermore, in the invention according to claim 2, the biomass fuel chip material and the carbonized material are treated in the case where deficiency occurs in the removal and combustion of wood ash which is a residue generated after each fuel is combusted. The auxiliary ignition burner is automatically ignited and the combustion deficiency can be canceled, and the automatic control device can effectively burn continuously.

なお、請求項3記載の発明では、供給された燃料が最大のカロリ−を放出するため火吹き竹原理の強制給気により完全燃焼燃焼を引き起こし、燃焼炉内部の温度を700℃から800℃に上昇させ安定、継続した燃焼を保ち、循環ポンプにより送られてくる水を効率よく加温するため、温熱利用しリタ−ンされた水は一時保存タンクに保存され、再度ボイラに送り込まれ加温水管内部で効率よく無駄なく加温された温水は、自動制御により蒸気の発生及び温水を発生し循環を繰り返えし、温熱利用に供することができる。  In the third aspect of the invention, since the supplied fuel releases the maximum calorie, complete combustion combustion is caused by forced air supply based on the fire-blown bamboo principle, and the temperature inside the combustion furnace is raised from 700 ° C. to 800 ° C. In order to maintain stable and continuous combustion and to efficiently heat the water sent by the circulation pump, the water returned using heat is stored in a temporary storage tank and sent again to the boiler where it is sent inside the heated water pipe. The hot water that is efficiently heated without waste can be used for heat generation by generating steam and hot water by automatic control and repeating the circulation.
