Product Description
Product Design:Water and Steam System: Horizontal water-tube structure. Softened feedwater is pre-heated via the pressurized economizer, producing steam in the membrane furnace and convection sections. Steam-water separation is achieved via steam-water baffles in the upper header. Multiple headers provide steam buffering and preheat feedwater to reduce corrosion and scaling.
Combustion and Exhaust System: Burner is located on the membrane furnace side. High-temperature flue gas passes through multi-pass convection and economizer sections. The serpentine gas tubes and laser-welded finned tubes in the economizer employ counterflow heat exchange to improve waste heat recovery.
Advantages Comparison
Energy Saving: Fast startup, high efficiency, low flue gas temperature, premium burners to save fuel.
Safety: Non-special equipment, low water capacity, multiple protections, explosion-proof.
Installation: No need for approval, notification, or inspection; simple setup.
Operation: No licensed operator required, reducing labor costs.
Annual Inspection: No mandatory inspections. Only safety valve and pressure gauge need user verification.
Overall Benefits:Compact, steel-saving, transportable, replaces traditional boilers, yields economic & social gains.
Technical Features:No annual insp., no license req., NOx<30mg/m³, pressurized econ., multi-level safety, counterflow heat exch., 3-min steam, adaptable burners.
Advantages Over Traditional Boilers

Using interdisciplinary design principles, it produces steam within 3 minutes and offers over 20% energy savings compared to traditional boilers. Key benefits include intelligent control, fast steam generation, high thermal efficiency, multi-pass heat exchange, alternate intelligent operation, on-demand energy supply, nearby installation, and anti-scaling features.
Comparison With Other Steam Boiler Types
Vs. Horizontal Steam Boiler:
No annual inspec., 1-2 min. steam gen., explosion-free, unmanned, >99% thermal eff., high dryness, compact, low flue gas (60-70°C), fast, smart ctrl., minimal maint.
Vs. LSS Once-Through Steam Generator:
Lower thermal loss in start/stop, reduced scaling, no dry burning, efficient at variable loads, lower chemical costs, easier maintenance, longer lifespan, stable feedwater, large steam capacity, excellent furnace insulation.
Vs. Steam Generators with <30L Water Volume:
DSS is a Class D boiler with strict standards, certifications, and supervision. It features reasonable water volume, clear water quality requirements, safe pressure, long lifespan, and stable structure (despite higher steel consumption), with no registration or annual inspection needed.
Advanced Structure:
The horizontal multi-pass water-tube boiler with headers achieves 0.8 MPa steam pressure in 3 minutes, featuring ample heating surface, high efficiency via internally welded fins, and an S-shaped economizer with laser-welded fin technology for energy savings. Pre-installed piping on the compact unit ensures easy installation/relocation, while the fully water-tube design eliminates explosion risks.
Easy Installation:
On-site setup only requires water, electricity, gas, and chimney connections for immediate commissioning, cutting down installation costs.
Flexible Configuration:
Standard burner configurations meet emission requirements; customization available upon request.
Eco-Friendly and Durable:
The new economizer lowers exhaust temperature and increases efficiency. Low-NOx pre-mixed burner ensures high combustion rate and low emissions, compliant with environmental standards. The unit's small water volume classifies it as a Class D boiler, requiring no dedicated boiler room or annual inspection, reducing labor costs.
Safe and Reliable:
Made of 20# boiler steel, complying with Class D standards. Water volume <50L, exempt from approval/inspection. Features automated operation with programmable ignition, multiple water feeding, overpressure/flameout protection. Easy to use/maintain, low cost, and quiet.
Efficient and Energy-Saving:
Micro-positive pressure combustion ensures full fuel burn. Cold start reaches rated pressure in 3 minutes, reducing start-up energy consumption.
Flexible Management:
Can be deployed in distributed layouts, reducing heat loss in the network. Suitable for modular replacement of steam boilers up to 6T/h.
Design Advantages:
Built-in large-capacity steam reservoir solves the issue of insufficient steam storage during low-load combustion.
Quality Assurance:
Standardized mass production, third-party inspection before delivery, reliable quality and low failure rate.
