FUEL COMBUSTION DEVICE
To provide a fuel combustion device capable of decreasing the amount of carbon dioxide to be discharged without using biomass fuel or a carbon dioxide recovery technique, and capable of controlling the generation of nitrogen oxides.SOLUTION: A burner 141 comprises a first main fuel feed port 141a that includes an annular opening having a center axis C1 and ejects main fuel not containing ammonia, second main fuel feed ports 141b to 141d disposed in the inner peripheral side area of the first main fuel feed port 141a, first auxiliary fuel feed ports 141f disposed in the outer peripheral side of the first main fuel feed port 141a with a gap apart from each other along the circular arc having the center axis C1 to eject auxiliary fuel containing ammonia, second auxiliary fuel feed ports 141e disposed between the first main fuel feed port 141a and the first auxiliary fuel feed ports 141f with a gap apart from each other along a circular arc having the center axis C1, and auxiliary fuel feed ports 141g disposed between the first main fuel feed port 141a and the second main fuel feed ports 141b to 141d with a gap apart from each other along a circular arc having the center axis C1.SELECTED DRAWING: Figure 11
【課題】バイオマス燃料又は二酸化炭素回収技術を用いずに二酸化炭素の排出量削減が可能で、且つ、窒素酸化物の生成を抑制可能な燃料燃焼装置を提供する。【解決手段】バーナー部１４１は、中心軸Ｃ１を中心とする環状の開口を有し、アンモニアを含まない主燃料を噴射する第１主燃料供給口１４１ａと、第１主燃料供給口１４１ａの内周側領域に配置される第２主燃料供給口１４１ｂ〜１４１ｄと、第１主燃料供給口１４１ａの外周側に中心軸Ｃ１を中心とする円弧に沿って間隔を空けて配置され、アンモニアを含む補助燃料を噴射する第１補助燃料供給口１４１ｆと、第１主燃料供給口１４１ａと第１補助燃料供給口１４１ｆとの間に中心軸Ｃ１を中心とする円弧に沿って間隔を空けて配置される第２補助燃料供給口１４１ｅと、第１主燃料供給口１４１ａと第２主燃料供給口１４１ｅとの間に中心軸Ｃ１を中心とする円弧に沿って間隔を空けて配置される補助燃料供給口１４１ｇとを有している。【選択図】図１１
