摘要:
A pulse combustion apparatus comprises (i) a single air supply section with a single air blower and (ii) a plurality of combustion sections each communicating with the air supply section. The air supply section includes passages communicating with both the blower and the respective combustion sections for admitting air from the blower into the respective combustion sections. The air admitting passages are physically separated from each other for separating air from the blower into streams which are not able to join together anywhere.
