Abstract: The present invention relates to a micro gas turbine with a compact structure. More specifically, a sub journal bearing is placed between a thrust collar and a wheel of a compressor which means the bearing is placed around the thrust bearing at a compressor so that the whole length and weight of a rotator are reduced to form the compact structure. A pair of main journal bearings separated from each other at a certain distance is placed between a hollow shaft and a sleeve. The main journal bearings fully support a shaft between the compressor and turbine wherein dynamic pressure is heavily applied caused by rotation in order to maximize safety. For the purpose, the present invention comprises a turbine wheel; a tie shaft which one end part is connected to the turbine wheel; a compressor wheel which is separated from the turbine wheel to be inserted into the tie shaft; a thrust rotor separated from the compressor wheel to be fixed to the end part of the tie shaft; the thrust collar placed on a part of the outer surface of the thrust rotor; and the sub journal bearing equipped between the thrust collar and the compressor wheel.

Abstract translation: 本发明涉及一种结构紧凑的微型燃气轮机。 更具体地说，副轴颈轴承放置在推力环和压缩机的轮之间，这意味着轴承以压缩机的方式放置在推力轴承周围，从而使转子的整个长度和重量减小以形成紧凑的结构。 在一定距离内彼此分离的一对主轴颈轴承放置在空心轴和套筒之间。 主轴颈轴承完全支持压缩机和涡轮机之间的轴，其中动态压力由于旋转而被大量施加，以便最大化安全性。 为此，本发明包括涡轮机轮; 一个端部连接到涡轮机叶轮的连接轴; 压缩机叶轮，其与涡轮机叶片分离以插入连接轴; 与压缩机叶轮分离的推力转子固定在连接轴的端部; 推力轴环放置在推力转子的外表面的一部分上; 轴承和压缩机轮之间配备的子轴承轴承。

Abstract: 본 발명은 연소 설비 배출 가스 중의 수은의 저감 방법에 관한 것이며, 보다 상세하게는 할로겐 화합물을 첨착한 활성탄을 분말상으로 연소 설비 배출 가스 중에 직접 혼합하여 투입하거나, 입상으로 고정상 흡착탑으로서 설치하여 배출 가스 중의 수은을 저감시키는 방법에 관한 것이다.
본 발명에 따라 연소 설비에 할로겐 화합물을 첨착한 활성탄을 사용하면 기존의 방법과 비교하여 연소 설비 배출 가스 중의 수은을 현저히 저감시켜, 연소 설비를 친환경적으로 운영할 수 있다.

Abstract: A method for reducing mercury from fuel gas is provided to significantly reduce the mercury from the fuel gas, thereby performing a bio-friendly operation of combustion facilities, by using halogenated compound-impregnated activated carbon. Mercury from fuel gas is reduced by directly mixing halogenated compound-impregnated activated carbon into discharge gas in a power type, installing a fixation-type adsorbing tower of halogenated compound-impregnated activated carbon, or performing the combination thereof. The halogenated compound-impregnated activated carbon is KI-impregnated activated carbon, or HCl-impregnated activated carbon.
