Product Introduction 1. The series of boilers feature a single drum arch tube plate longitudinal arrangement, with double collecting boxes and wing-shaped flue channels, three-pass threaded flue tubes, central symmetry, self-supporting quick assembly layout, compact structure, and easy installation and transportation. 2. The arch tube plate increases the flexibility of the drum, simplifying the structure of the drum and enabling the boiler capacity to be large-scale. 3. The wing-shaped flue channel effectively addresses the problem of cracking in high-temperature tube plates by reducing the thermal stress difference in the tube plate. The threaded flue tubes of the heat transfer elements increase the heat transfer coefficient, cause turbulence in the flue gas, reduce tube internal ash accumulation, and improve the boiler's thermal efficiency while making the structure more compact. 4. The new furnace arch designed using the 3-3-2 rule has strong coal adaptability, optimizes the combustion in the furnace chamber, reduces the generation of black smoke and lowers the original dust emission concentration compared to traditional furnace types, ensuring the boiler's smoke and dust emissions meet environmental protection requirements. 5. The water supply is equipped with automatic control and features an overpressure and water shortage automatic interlock device, ensuring reliable boiler operation.
