Abstract: front page image
(EN)Generation of slagging is suppressed in a pulverized coal burner. A nozzle body (6) opening toward a furnace (1), carrying pulverized coal and injecting it together with primary air (14) finally becoming combustion air has an outer tube nozzle (8), and an inner tube nozzle (9) provided in the outer tube nozzle (8) concentrically thereto. A fuel conduction space (10) is formed between the outer tube nozzle (8) and the inner tube nozzle (9), and at least one of the outer tube nozzle (8) and the inner tube nozzle (9) is provided with a straightening plate (29) projecting into the fuel conduction space (10) and extending in the axial direction of the nozzle body. The combustion air (primary air (14)) containing pulverized coal is ejected through the fuel conduction space (10).
(FR)La génération d'une scorification est supprimée dans un brûleur à charbon pulvérisé. Un corps de buse (6) s'ouvrant vers un four (1), transportant du charbon pulvérisé et l'injectant conjointement avec de l'air primaire (14), devenant finalement de l'air de combustion, a une buse de tube externe (8) et une buse de tube interne (9) disposée dans la buse de tube externe (8) de façon concentrique à celle-ci. Un espace de conduction de combustible (10) est formé entre la buse de tube externe (8) et la buse de tube interne (9), et au moins l'une de la buse de tube externe (8) et de la buse de tube interne (9) est dotée d'une plaque de redressement (29) se projetant dans l'espace de conduction de combustible (10) et s'étendant dans la direction axiale du corps de buse. L'air de combustion (air primaire (14)) contenant du charbon pulvérisé est éjecté à travers l'espace de conduction de combustible (10).
(JA) 微粉炭バーナに於いてスラッギングの発生を抑制する。  火炉1に向って開口し、微粉炭を搬送し且つ最終的に燃焼用空気となる1次空気14と共に噴出するノズル本体6が、外筒ノズル8と、該外筒ノズル8の内部に該外筒ノズル8と同心に設けられた内筒ノズル9とを有し、前記外筒ノズル8と前記内筒ノズル9との間に燃料導通空間10が形成され、前記外筒ノズル8と前記内筒ノズル9の少なくとも一方に前記燃料導通空間10に突出し、前記ノズル本体軸心方向に延びる整流板29を設け、微粉炭を含む前記燃焼用空気(1次空気14)が前記燃料導通空間10を通って噴出される様構成する。
