In response to the clean energy policies of "Blue Sky Protection Campaign" and "Dual Carbon Goals," an increasing number of enterprises and factories are seeking safer, more eco-friendly, and energy-efficient heat source equipment.

Traditional steam boilers have large water storage, high startup energy consumption, and safety risks. Devotion, after three years of dedicated research, has innovatively launched the condensing variable frequency steam generator. It features a water storage capacity of less than 30 liters, eliminating the need for a usage permit or annual inspections. It also includes unique steam generation technology, a compact footprint, low nitrogen emissions, fast steam production, low energy consumption, high steam quality, and a high level of automation.

Product Structure

• Siemens Mixer:
  German brand, original imported, precisely mixes gas and air over a wide adjustment range.

• Siemens Gas Valve:
  German brand, original imported, ensures precise gas flow control with a zero-pressure system for enhanced safety. Tested over 200,000 start-stop cycles.

• AMETEK Fan:
  American brand, original imported, low-noise, high airflow, with infinitely variable speed control. Tested over 100,000 start-stop cycles.

• Bekaert Burner:
  Original imported from Belgium, features micro-flame holes for uniform flame distribution and complete combustion, leading to ultra-low NOx emissions.

• Condenser:
  Made of 316L stainless steel heat exchange tubes, laser welded for durability. Large drainage outlets ensure smooth condensate discharge, with a large heat exchange area and flue gas temperatures reduced to below 60°C.

• Once-through Boiler Body:
  Made of special high-pressure, high-temperature boiler steel, with dual argon arc welding and built-in stainless steel finned heat exchange tubes.

• Air Filter:
  With an increased filter area, it captures more dust for better air quality, offering a longer lifespan and easy replacement.

• Water Pump:
  Made from stainless steel, powered by 1.1/1.5 kW, from a renowned domestic brand.

Product Features

• Safe and Reliable, No Inspections Required:
  With a small water volume, there is no explosion risk. Tested water volume from the feed pump to the steam outlet is less than 30 liters, meeting the latest Boiler Safety Technical Regulations (TSG11-2020). It requires no inspections and has no explosion risk.

• Multiple Safety Features:
  Equipped with wind pressure, water cutoff, flameout, over-temperature, over-pressure, and gas leak detection systems that provide timely alarms and ensure long-term stable operation.

• Stable Combustion System:
  Uses an advanced combustion control system and gas valve components, certified by combustion tests for stable and safe operation.

Fully Premixed Combustion Technology

• NOx Emissions Below 30mg/m³:
  1. Natural gas and air are fully premixed inside the fan and burner head for more complete combustion.
  2. The load is automatically adjusted for more stable combustion and steam pressure.
  3. The fully premixed metal fiber burner effectively reduces flame temperature, minimizing NOx generation.

Enhanced Evaporation Technology

• Twice Steam-Water Separation Produces Higher Quality Steam:
  Internal dual steam-water separation ensures high-quality steam output. Each heat exchange tube undergoes preheating, boiling, steam-water separation, superheating, and another steam-water separation process, producing steam with up to 98% dryness. No external steam-water separator is needed.

• Low Startup Energy Consumption, Faster Steam Output:
  Due to the small water storage volume, water heats quickly, producing steam in just 30 seconds, allowing instant steam availability.

High-Efficiency Condensing Heat Exchange Technology

• Efficiency ≥101%, Super Energy-Saving:
  High-temperature flue gas from the fully premixed combustion process is cooled by the condenser. Cold water inside the finned tube absorbs residual heat from the flue gas, reducing the flue gas temperature to below 60°C and achieving an efficiency of up to 101%.

Compact Design, Small Footprint

• Easy Transport, Quick Installation:
  Compared to traditional fire-tube boilers, the overall size is reduced by two-thirds, making it easier to transport and ideal for users with limited space or those undergoing low-nitrogen retrofitting.

• Flexible Layout:
  Can be installed close to the production area without the need for a dedicated boiler room, reducing infrastructure investment costs.

• Comprehensive Installation Documentation:
  Equipped with complete installation instructions for easy setup. The system is pre-tested and adjusted at the factory, requiring only minimal on-site adjustments.

Intelligent Control and Remote Monitoring

• Unattended Operation, On-Demand Steam:
  Fully automated control with a user-friendly Chinese touch screen, allowing for scheduled startup/shutdown and automatic on-demand steam generation, improving management efficiency. With IoT technology, real-time monitoring of operational status can be done via phone or computer.

• Modular System for Efficient Steam Supply:
  The intelligent group control system uses logic-based judgment to adjust the load and number of operating units based on steam demand, ensuring optimal efficiency. It also allows for batch maintenance of equipment without affecting production.

Comprehensive Quality Management

• Guaranteed Product Quality:
  As a national A-grade boiler manufacturing company, Devotion has a complete quality assurance system. Each product is inspected, and a certificate of conformity is issued before leaving the factory.

• Strict Factory Testing Procedures:
  The boiler body, condenser, and piping undergo over 20 tests, including water pressure, air-tightness, and 30 minutes of full-load combustion, ensuring that every product meets standards before shipping.
