초록

SM탄(인도네시아산)을 이용하여 NOx 배출 특성을 조사하였다. 실험은 석탄 거치 후 승온하며 연소하는 방법과 승온 후 석탄을 주입하는 방법을 이용하였다. 산소희박 분위기에서는 배출 NOx가 연소온도와 반비례의 관계를 나타내었으며 이는 fuel N이 강한 환원 분위기에서 N2로 전화되기 때문인 것으로 나타났다. 또한 주입 가스량 증가 시에는 산화 분위기에 의해 fuel N이 NO로 산화되어 total fuel NO가 증가하는 경향을 나타내었다. 제조 온도에 따른 char의 연소시 발생되는 NO의 분석으로 total fuel N, volatile-N, char-N이 각각 NO로 전화되는 부분으로 구분될 수 있었으며 실험결과 본 연구에 사용된 SM탄은 total NOx의 대부분이 volatile-N에 기인하는 것으로 나타났다.

This article describes NO emission characteristics in SM coal combustion. Combustion experiments was performed in the method of increasing temperature after feeding coal and feeding coal after increasing temperature. NOx emission is in inverse proportion to combustion temperature at the fuel rich condition and it was caused by conversion fuel N to N2 at the strong reduction condition. In addition, feeding gas flow rate increased as total fuel NOx increase by conversion of fuel N to NO at the oxidation condition. It could be separated in total fuel-N, volatile-N, char-N to NO according to analysis of total fuel NO emission from char combustion at each temperature. In the result, almost total NOx emission was caused by volatile-N in SM-coal.

Keywords:coal combustion;char-N;reduction;NOx emission
