Fuel: Natural gas, coke oven gas, blast furnace gas, carbon black tail gas, biogas, diesel, heavy oil, light oil, crude oil, etc.
Industries: Heat supplying, chemical, food, textile, printing and dyeing, cigarettes and tobacco, fodder, pharmacy, building materials, brewery, rubber, hospital etc.
The SZS series D type water tube boiler is characterized by two main water drums (upper drum and lower drum) and a convective tube bundle located between them, which provides high water circulation efficiency and combustion space. This configuration enables the D-type water tube boiler to perform well in high-temperature and high-pressure applications and meet various industrial needs. The boiler is equipped with multiple safety protection systems, including over-temperature, over-pressure, low water level, and flameout protection devices, ensuring the safe operation of the boiler under various working conditions. The boiler body is made of high-strength steel and advanced manufacturing processes, providing excellent high-temperature and high-pressure resistance and long service life.
Environmental Friendliness and Energy Saving: The SZS series D type water tube boiler adopts low-nitrogen combustion technology and advanced flue gas recirculation system, effectively reducing the emissions of pollutants such as NOx and meeting strict environmental standards. The boiler achieves complete combustion with low particulate matter and harmful gas emissions in the flue gas, resulting in minimal environmental impact and contributing to green production for enterprises.
Stable Operation: This SZS series D type water tube boiler adopts advanced control systems and automatic regulation devices, realizing fully automatic control of boiler operation with easy operation and stable performance. The boiler’s water circulation system is designed reasonably, ensuring stable operation under various loads, providing high-quality steam with minimal fluctuations, and meeting different user requirements.
High Thermal Efficiency: The combination of membrane water-cooled walls and a large furnace design improves heat transfer efficiency, while the economizer reduces the exhaust gas temperature.
Convenient Maintenance and Operation: The advanced control system allows for unmanned operation.
