建立了一个热循环式燃烧器的实验装置，并对甲烷/空气和低热值燃料/空气稳定燃烧的热力特性进行了研究。通过实验和数值模拟相结合的方法，确定了燃烧器通道内空气和燃气的纵向温度分布。以热回流率和热效率作为燃烧器传热性能的评价指标，对燃烧器的化学参数（当量比）、流体力学参数（雷诺数）和几何参数（通道数）进行了优化设计。
An experimental burner of the heat-recirculating type was constructed and its thermal characteristics were investigated for steady methane/air and low-calorific-fuel/air combustion. Longitudinal temperature distributions of air and burned gas flowing in the passes of the burner were determined by means of both experiments and numerical simulations. Using the heat recirculation rate and the thermal efficiency as criteria for the heat transfer performances of the burner, the optimal design of the burner was examined in terms of a chemical parameter (the equivalence ratio), a fluid-mechanical parameter (the Reynolds number) and a geometrical parameter (the number of passes).
