The Fangkuai Commercial Hot Water Boiler C Series features a vertical design that integrates advanced technologies for significant breakthroughs in various aspects. Utilizing FGR diffusion combustion technology, the burner ensures complete fuel combustion and cleaner emissions, aligning with international air quality standards. Tests show that the boiler can achieve a flue gas temperature as low as 50°C under low-temperature conditions, with an impressive thermal efficiency of up to 106%. This makes it a highly efficient and low-emission environmental solution. With a pressure rating below 4 bar, the boiler is exempt from inspection and registration, making it a practical choice. Its compact size occupies minimal floor space, while the heat exchange surface of the wing tube is 13 times greater than that of seamless tubes. This efficient design allows for significant volume reduction, enabling easy transport via elevators. Installation is straightforward, as performance is fully tested at the factory. All components are clearly labeled for easy connection to water, electricity, and gas lines on-site. When used for heating, the product can be directly integrated into existing heating water systems without the need for additional heat exchange equipment, significantly lowering upfront investment costs.
This condenser and energy-saving device leverages the heat exchange principle between water and flue gas, offering rapid heat transfer, energy efficiency, and durability. By cooling the flue gases, it effectively raises the temperature of the boiler feed water, optimizing overall system performance.
The air-energy water heater uses main and auxiliary fan technology to heat incoming air with high-temperature condensate. The auxiliary fan mixes some flue gases with the airflow, allowing for precise temperature control at each stage, which stabilizes combustion and reduces emissions.
The corrugated furnace lining fully absorbs the extension and expansion of the furnace lining wall, ensuring low-stress operation under any working conditions. The higher furnace back pressure improves the stability of the flame and provides more space for FGR adjustment; The effective application of wing technology can significantly reduce the boiler body diameter, water volume, and start-up time.
An air heater preheats the combustion air, supplying hot air for combustion and effectively addressing instability from condensation in the system. By raising the combustion air temperature above the dew point, it significantly enhances combustion efficiency.
