Description
この考案は、従来のガス又は油焚燃焼設備において、代替燃料としてバイオマスや有機性廃棄物を効率よく燃焼させるための燃焼装置に関するものである。 The present invention relates to a combustion apparatus for efficiently burning biomass or organic waste as an alternative fuel in a conventional gas or oil tank combustion facility.
従来から、燃焼装置としては、バイオマスバーナー（例えば、特許文献１参照）、ガス化燃焼方式（例えば、特許文献２参照）等が一般的である。
このようにバイオマスや有機性廃棄物等を従来の諸方式で燃焼するには、燃焼効率が低く、安定した燃焼が得られず、焼却灰の処理も煩雑であった。 Thus, in order to burn biomass, organic waste, etc. by various conventional methods, combustion efficiency is low, stable combustion cannot be obtained, and incineration ash processing is complicated.
また、固体燃料の場合、乾燥、ガス化、燃焼するまでに大量の熱が必要であり、固体燃料の攪拌を行なっても完全に灰化することは困難である。 In the case of a solid fuel, a large amount of heat is required until it is dried, gasified, and burned, and it is difficult to completely ash it even if the solid fuel is stirred.
本考案は、上記の問題点を解決するために内部に螺旋溝を備えた回転筒の基部からバイオマス燃料と燃焼空気を供給し、補助バーナーとの混焼により連続的に乾燥、ガス化、燃焼、灰化を先端部に向って安定して行うことを可能にした。 In order to solve the above problems, the present invention supplies biomass fuel and combustion air from the base of a rotating cylinder provided with a spiral groove inside, and is continuously dried, gasified, combusted by co-firing with an auxiliary burner, It became possible to perform ashing stably toward the tip.
以上に説明したように、本考案のバイオマス燃料や有機性廃棄物のバイオマス燃焼装置は、従来不向きだった加圧燃焼が出来、バイオマスバーナーとして、既存のガスや油焚きバーナーと併用することで兼価な燃焼を提供でき、装置の小型化、作業の省力化等の効果を有し、バイオマス燃料や有機性廃棄物の燃焼に適した安定した連続ガス化燃焼が出来る。 As explained above, the biomass combustion apparatus for biomass fuel and organic waste according to the present invention can perform pressurized combustion, which has been unsuitable in the past, and can be used as a biomass burner in combination with existing gas or oil burning burners. Can provide stable combustion, and has effects such as downsizing of the apparatus and labor saving, and stable continuous gasification combustion suitable for combustion of biomass fuel and organic waste can be achieved.
本考案の実施例を添付図面にもとづき説明する。図１はバイオマス燃焼装置の断面図である。

バイオマス燃料投入口（７）の固形燃料による閉鎖及び加圧燃焼時バイオマス供給バルブ（１０）方向への高温ガスの逆流を防ぐための一次燃焼空気入口（６）、二次燃焼空気入口（８）はそれぞれ調整弁を介しターボファンに連接している。 The primary combustion air inlet (6) and the secondary combustion air inlet (8) for closing the biomass fuel inlet (7) with solid fuel and preventing the backflow of hot gas in the direction of the biomass supply valve (10) during pressurized combustion Are connected to a turbofan via a regulating valve.
固形燃料はバイオマス供給バルブ（１０）より定量供給されバイオマス燃料投入口（７）より回転筒（１）内に備えた螺旋溝（１３）に供給され、回転筒（１）の燃焼速度に合せた回転により安定した乾燥、ガス化、燃焼、灰化が出来、炉内（３）の灰だし装置（１４）より外部に排出される。 The solid fuel is quantitatively supplied from the biomass supply valve (10), supplied from the biomass fuel inlet (7) to the spiral groove (13) provided in the rotary cylinder (1), and matched with the combustion rate of the rotary cylinder (1).
