What type of combustion can is considered most efficient in centrifugal type compressors?

• A. Single chamber can
• B. Multi-chamber can
• C. Composite can
• D. High-pressure can

Answer: (B)

In centrifugal type compressors, the most efficient combustion arrangement is the multi-chamber can. This design consists of multiple combustion chambers that allow for a more uniform and comprehensive combustion process. The multi-chamber configuration enhances the mixing of fuel and air, promoting better combustion efficiency, which is crucial for optimizing the performance of the engine. The multi-chamber can configuration helps maintain stable combustion at various operating conditions and load levels. It also contributes to minimized emissions and improved thrust-to-weight ratios, making it favorable for turbine applications. In comparison to other configurations, having multiple chambers allows for quicker ignition and better flame stability, which can be particularly important in high-performance applications where rapid changes in engine conditions occur. In contrast, single chamber cans may not achieve the same level of efficiency due to limitations in air-fuel mixing and stability over a range of operating conditions. Composite cans and high-pressure cans, while useful in specific applications, do not provide the same balance of efficiency and performance as seen with multi-chamber designs in centrifugal compressors. Thus, the multi-chamber can stands out as the superior choice in this context.
