中文摘要 | 複循環機組係由氣渦輪機及汽輪機產生電力,氣渦機燃料可能包括各種燃料油與 燃料氣,而本文僅提出壞慮煤炭氣化產生的燃料氣,嘆其脫硫之各種方法,從氣渦輪機排 出的熱燃氣之廢熱用於產生供給汽輪機蒸氣。 煤炭氣化複循環機組與慣常的燒榮電廠比較,具有以下優點: 1.煤炭氣化複循環機組的綜合效率為45%,優於幾乎不能達40%之慣常燒煤機組,意即比慣 常燒煤電廠節省用量。 2.設備裝置之容積尺寸較小。 3.環境污染較低,因採用這種新理念,有毒之SO、灰塵煤煙排入大氣中之含量較少,但NO之 排放量並未稍減。 |
英文摘要 | The electricity of combined cycle units is produced via gas and steam t urbines. The fuel for gas turbines may consiist of various fuel oils and gases but in this article, it is proposed to consider only those gases which are porduced fromm gasification of coal, and its cedulphurizatiom processes. The,waste heat of the hot combustion gases from the gas turbine is used to produ ce steam for the steam turbines. As opposed to a comventional coal power, the following advantages cam be obtained from a coal gasification combined cycle unite: 1.Better overall efficiencv of the power plant (approximately 45 % as opposed to barely 40 % ), which means for a coal gasification combined cycle unit of equal effieciency less coal is need than a conventional power unit. 2.Smaller size of site. 3.Lower environmental pollution, because with this new concept the noxious substances. SO, dust and soot that arrive in the environment - but not NO- can be reduced appreciably. |
