AI Technical Summary
Existing gas-fired boilers suffer from uneven heating and difficulty in temperature control during the heating process, leading to overheating in localized areas and affecting safety and efficiency.
The water-cooled structure design uses a circulating pump to draw water from the cooling tank and heat exchange tubes to absorb heat in the heating chamber. The combination of circulating and return pipes ensures that the water temperature in the steam tank rises evenly and prevents local overheating.
This achieves uniform temperature control within the boiler, improving safety and efficiency, preventing equipment damage caused by localized overheating, and ensuring stable operation of the device.
