Features of DZS Ultra-Low NOx Gas Fired Steam Boiler:
1. Membrane Wall Structure: The combustion chamber adopts a membrane wall water-cooling design with a typical natural circulation system, ensuring high reliability and a self-compensating ratio for automatic water distribution. The water circulation is safe and reliable, and the water volume is only 1/5 of conventional boilers. The boiler body is designed with a water tube and threaded fin tube structure, making it safer and more energy-efficient than conventional fire tube boilers.
2. Automatic Water Supply: The automatic water supply system controls the water supply based on changes in water level and water flow, ensuring stable system operation.
3. Higher Energy Efficiency: It utilizes an efficient condensing economizer to fully recover the latent heat of flue gas, reducing flue gas temperature to as low as 60°C, achieving a high thermal efficiency of up to 101%. The control system adopts dual-pressure and temperature control, increasing control sensitivity by 50%. The number of start-ups and shutdowns of the low-load combustion unit decreases by 35%, and the pre-blowing energy consumption is reduced by 35%, resulting in an overall 2% energy-saving improvement.
4. Enhanced Safety: The smaller water volume ensures a higher safety factor.
5. Variable Frequency Regulation: Achieving 20%-100% stepless variable frequency regulation of input power, accurately controlling the inlet and return water temperature and controlling the temperature rise rate to efficiently utilize energy.
6. Compact Design: The boiler is compactly designed, with small dimensions, occupying a small footprint, and having a rational and aesthetically pleasing layout.
7. Environmentally Friendly: It achieves NOx emissions below 30mg/m3, meeting the strictest environmental standards and actively responding to national energy-saving and emission reduction policies.
8. Comfortable and Quiet: The boiler operates quietly with low noise levels, as low as 80 decibels.
9. Dual Safety Protection: The boiler is equipped with two or more steam safety valves, dry-burning protection system, high-pressure shutdown, low water level, ultra-low water level alarm, and interlock protection.
10. Cloud Services: Equipped with loT remote monitoring system, it provides remote operation and maintenance services. Through the GPRS cloud platform, the real-time operation status of various parts of the boiler can be viewed on computers, mobile phones, and other devices.
