Product Introduction 1. The series of boilers utilize a single drum arch tube plate longitudinal arrangement, with double collector box wing-shaped flue, three-pass helical flue tubes, centered symmetry, self-supported 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 enlarged. 3. The wing-shaped flue effectively solves the problem of cracking in high-temperature tube plates by reducing the thermal stress on the tube plate. The threaded flue tubes of the heat transfer elements increase the heat transfer coefficient, disturb the flue gas, reduce tube ash accumulation, enhance the boiler's thermal efficiency, and make the structure more compact. 4. The new furnace arch designed with the 3-3-2 principle has strong coal species adaptability, optimizes the combustion chamber combustion, 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.
