Title (EN) COMBUSTION METHOD
(FR) PROCÉDÉ DE COMBUSTION
(JA) 燃焼方法
Abstract:
(EN) Provided is a combustion method that minimizes incomplete combustion and the generation of nitrogen oxides. In this combustion method, combustion is performed in a thermal power house 1 that generates electricity by combusting pulverized coal and ammonia in a boiler 6. The mixed burning ratio of the ammonia to the pulverized coal used in combustion in the boiler 6 is 0.8% or greater.
(FR) L'invention concerne un procédé de combustion qui réduit au minimum la combustion incomplète et la production d'oxydes d'azote. Dans ce procédé de combustion, la combustion est effectuée dans une centrale thermique (1) qui produit de l'électricité par combustion de charbon pulvérisé et d'ammoniac dans une chaudière (6). Le rapport de combustion mixte de l'ammoniac au charbon pulvérisé utilisés dans la combustion dans la chaudière (6) est supérieur ou égal à 0,8 %.
(JA) 窒素酸化物の発生や不完全燃焼を極力抑える燃焼方法を提供する。 本発明の燃焼方法は、微粉炭及びアンモニアをボイラ6において燃焼させて発電を行う火力発電設備1で実行される燃焼方法であって、ボイラ6での燃焼に用いられるアンモニアの微粉炭との混焼率が、0.8%以上である。
