中文摘要：
加热器在热声发动机的能量传递和转化过程中起着重要作用，是热声发动机的核心部件之一。目前热声发动机大多采用电能驱动，采用燃气直接燃烧驱动将对热声发动机的实用化具有积极促进意义。根据热声发动机的工作特点，以时均流对流换热公式为依据，设计了一种新型燃气燃烧驱动加热器，并应用于现有的混合型热声发动机实验台上，取得了较好的实验结果。
英文摘要：
Heater is one of the key parts in thermoacoustic engines for its function on converting and transferring energy. At present, most thermoacoustic engines are driven by electricity, while the ones driven by combusting gas can further promote the practical application of thermoacoustie engines. Based on the time - averaged convective heat transfer method and the characteristics of thermoacoustie engine, a new kind of heater driven by combusting gas is designed and applied to a thermoacoustic Stirling engine, which was previously driven by electricity. The experiment results indicate that the heater can meet the heating requirement of the engine.
