[0002] Bubble lotus rhizome is a very popular snack food, and the lotus rhizome used in bubble lotus rhizome is packaged and transported into a high-temperature sterilization process after processing. The horizontal gas steam boiler provides high-temperature steam for sterilization. A gas boiler is generally composed of a furnace, a second return flue, a third return flue, a boiler shell, a back-pumping chamber, front and rear smoke boxes, and a burner. After the gas boiler is filled with water, it can be ignited. The flame and smoke generated by combustion heat the water in the boiler through the furnace and the second and third return flues to produce high-temperature steam. The smoke is finally discharged into the rear smoke box through the chimney.

[0003] During combustion, the first return of the smoke flow is the smoke generated by combustion flowing from front to back in the furnace. Then it flows through the second and third return flues. As can be seen, the heat utilization of the smoke is crucial to the boiler. The existing steam boiler has limited space for smoke flow, which results in a short residence time of the smoke in the boiler. Therefore, the heat of the smoke is not fully utilized, and the discharged smoke still has a high temperature. Therefore, to improve the heat energy utilization rate of the steam boiler, we provide a horizontal gas steam boiler for bubble lotus rhizome processing. SUMMARY
