| The 5 kinds of common gaseous effluents were selected for analytical objects in the process of coal gasification such as NH3, HCN, H2S, COS, and CS2. Based on the fundamental principle of sampling method for isokinetic and non isokinetic sampling system, sampling systems for both atmospheric gasification and pressured gasification at home and abroad were contrasted and analyzed. Some common chemical and instrumental analysis methods were listed. The recent achievements for reliable analysis on gaseous effluent were summarized to provide conception and reference for designing sampling system especially for pressured coal gasification. |
