摘    要:对于垃圾气化的转换效率,传统上采用冷煤气效率来表示,采用(火用)方法并提出了(火用)效率和累积(火用)效率。根据冷煤气效率、(火用)效率和累积(火用)效率对垃圾气化的3种气化剂进行比较,发现依照3种效率选取的最佳气化剂不尽相同。分析可得:(火用)方法要比传统方法更全面更具实践价值,(火用)效率和累积(火用)效率强调了合成气焓(火用)的利用潜力。由于累积(火用)效率兼顾到了气化剂获取的能耗成本,从而可为气化剂的科学选取提供依据。

关 键 词:(火用)  气化  合成气  (火用)效率  累计(火用)效率

Abstract:As to the conversion efficiency of waste gasification, cold gas efficiency (CGE) has been traditionally used. In this paper the exergy method was adopted, and exergy efficiency and cumulative exergy consumption (CExC) efficiency were put forward. CGE, exergy efficiency and CExC efficiency were compared among three agents for waste gasification. It was found that the best agent was different according to different efficiencies. The exergy method was more comprehensive and had more practical value than traditional method. The exergy efficiency and CExC efficiency emphasized the utilization potential of enthalpy exergy carried by syngas. As the CExC efficiency took the energy cost of acquiring agents into consideration, it can provide proof for the scientific selection of agents.
Keywords:exergy  gasification  syngas  exergy efficiency  cumulative exergy efficiency
