摘要
根据燃气物理化学性质的分析，比较燃气燃烧速度、火焰热量分布、温度的高低，阐述了乙炔、丙烷、丙烯、甲基乙炔－丙二烯稳定燃气（ＭＰＳ）及液化石油气、天然气等燃气燃烧特性对火焰切割性能的影响。最后对燃气的选用进行了讨论。
This paper analyzes fuel gases for physical and chemical properties and compares their burning velocity, distribution of heat and temperature of the flame. It interprets the influence of the burning characteristics of acetylene, propane, propylene, methylacetylene-propadiene (MPS), liquified-petroleum gases and natural gas on the oxyfuel cutting. Finally the selection of feul gases for oxyfuel cutting are discussed.
