Key Features
Advanced water tube structure and optimized combustion system achieve 90–92% thermal efficiency, reducing fuel consumption and operating costs.
Designed for continuous industrial operation with stable pressure and saturated steam, ensuring reliable production processes.
Integrated intelligent control system automatically manages ignition, combustion, water level, pressure, alarms, and safety protection, minimizing manual intervention.
Manufactured using high-quality boiler steel with precision welding and strict non-destructive testing for long service life under demanding industrial conditions.
Modular design simplifies transportation, installation, inspection, and routine maintenance, helping reduce downtime.
Engineered for Heavy Fuel Oil (HFO) Challenges
Heavy fuel oil presents distinct operational hurdles compared to standard diesel or natural gas. Our SZS series integrates specific engineering controls to guarantee stable atomization and prevent common HFO issues:
1. Viscosity & Temperature Control
Dual-Stage Fuel Preheating System: Maintains oil temperature between 110°C–130°C before atomization to ensure optimal viscosity (<20 cSt).
Steam/Electric Hybrid Heating: Utilizes boiler self-generated steam during normal operation and electric auxiliary heating during cold starts.
2. Anti-Coking & Nozzle Maintenance
Air/Steam Atomization Burners: Ensures complete combustion of heavy hydrocarbon fractions, reducing carbon soot buildup by up to 35%.
Automatic Nozzle Purging System: Automatically flushes burner nozzles with compressed air or light diesel prior to shutdown, preventing clogging caused by residual oil cooling inside the nozzle.
3. Low-Temperature Corrosion Protection
Variable Low-Temperature Corrosion Prevention: Acid dew-point monitoring integrated with an adjustable feed-water temperature control loop (maintaining water inlet >105°C) to extend economizer lifespan when burning high-sulfur heavy oil.
Optional Configurations
To meet different industrial requirements, the boiler can be customized with:
Burner brands (Riello, Baltur, Weishaupt or equivalent)
PLC control system upgrades
Touch screen HMI
Economizer
Condensing heat recovery system
Continuous blowdown system
Feed water treatment system
Steam superheater
Remote monitoring module
Customized voltage and electrical standards

Frequently Asked Questions
Q: What fuel does this boiler use?
A: This model is designed for heavy oil. Other fuel options such as natural gas, diesel, or dual-fuel configurations are available based on project requirements.
Q: What certifications do your boilers have?
A: Our boilers can be supplied with ASME, CE, ISO 9001, and other certifications depending on project specifications and destination market.
Q: Can the boiler operate continuously for 24/7 industrial production?
A: Yes. The boiler is designed for continuous industrial operation under rated working conditions. Proper water treatment, scheduled maintenance, and regular inspections help ensure stable long-term performance and maximize service life.
Q: What information is required to recommend a suitable boiler model?
A: To recommend the appropriate model, we typically need the required steam capacity, working pressure, fuel type, feed water conditions, installation location, altitude (if applicable), and details of the intended industrial application.
Q: Is the boiler compatible with existing steam systems?
A: In most cases, yes. The boiler can be integrated into existing steam pipelines and auxiliary systems. Our engineering team can review your project specifications and recommend suitable interface configurations before production.
Q: Are spare parts available for long-term operation?
A: Yes. We provide a long-term supply of genuine spare parts and consumable components. Recommended spare parts lists can also be supplied with the order to help reduce future maintenance downtime.
