以某型双燃料燃气轮机燃烧室为研究对象，采用天然气及-10号柴油为燃料在额定工况下利用热平衡迭代法计算了火焰筒一维壁温。计算表明: 使用不同燃料时，火焰筒壁温分布趋势基本一致；由于燃料组分中碳氢比不同，使用柴油燃料时火焰筒壁温更高；沿燃气流动方向，两种燃料条件下的火焰筒壁温差异程度越来越大。

Taking a kind of dualfuel gas turbine combustor chamber as the research object, using natural gas and -10# diesel as the fuel, the onedimensional wall temperature was calculated by using the iterative method of heat balance under rated working conditions. The calculation results show that: the liner wall temperature distribution trend is similar when different fuels are used. Because of the different C/H ratio in fuel components，the wall temperature of liner is higher when diesel fuel is used . Along the gas flow direction, the liner wall temperature difference is more and more significant under the different fuel conditions.
