How should a food factory choose a corresponding supporting boiler when using a double-layer kettle?

When selecting a boiler for jacketed kettles in a food factory, it is essential to balance energy efficiency and operational effectiveness. Using a boiler that is too large wastes energy, while one that is too small may be inefficient. Based on practical applications, the following gas consumption rates per hour are provided for reference:

- **50L Kettle**: 33kg

- **100L Kettle**: 44kg

- **200L Kettle**: 72kg

- **300L Kettle**: 110kg

- **400L Kettle**: 136kg

- **500L Kettle**: 165kg

- **600L Kettle**: 190kg

For double-layer kettles, it is generally recommended to use a boiler with a minimum hourly gas output of **300kg** and a pressure of at least **3kg**. These specifications should be adjusted based on the specific operational requirements of the factory, and consultation with experienced industry peers is advised for reliable selection.
