Commercial Gas Condensing Technology

In commercial gas condensing technologies (such as large condensing boilers and industrial waste heat recovery systems), fans are core components for combustion efficiency, waste heat recovery, emission control and system stability, directly affecting equipment energy efficiency, operating costs and environmental compliance.

 

Ventilation and Coling Fan

  1. Precise combustion control and air-fuel ratio optimization

 

  • The variable frequency fan dynamically adjusts the air volume according to the gas flow rate (the air-fuel ratio of natural gas is 10:1, and the hydrogen mixed gas requires higher precision) to ensure complete combustion (CO emissions <30ppm, NOx <50mg/m³).
    • Data: The thermal efficiency of commercial condensing boilers can reach 95%-108% (low calorific value → high calorific value), which saves 20%-35% energy compared to traditional boilers.
  • Flame stabilization and anti-flashback: The high-pressure fan maintains a slight positive pressure in the combustion chamber (100-300Pa), stabilizes the flame shape, and prevents airflow disturbance from causing flameout.

 

  1. Efficient waste heat recovery

 

  • Flue gas condensation: The fan forces the high-temperature flue gas (150-250℃) to flow through the stainless steel heat exchanger, and the water vapor condenses to release latent heat (recovered heat >15%), and the exhaust temperature drops to 50-60℃.
  • Cascade utilization: Multi-stage heat exchanger + multi-fan synergy, the flue gas heat preheats the air and heats the process water in turn, and the comprehensive energy efficiency is improved by 30%.

 

  1. Environmental protection and safety

 

  • Low emission guarantee: Ultra-low nitrogen combustion technology (FGR flue gas recirculation) relies on high-precision fans to control the recirculation rate (10%-30%), and NOx emissions are less than 30mg/m³ (national standard GB 13271).
  • Fault protection: The wind pressure sensor monitors the flue resistance (>150Pa alarm), and the gas supply is cut off in conjunction to prevent CO accumulation.
