Product Introduction

Question 1-Product Description

SHORT DESCRIPTION

♦ Gas burner.

♦ Single-stage operation.

♦ Air-gas mixing at the air duct.

♦ By adjusting the combustion air and the air duct, it is possible to obtain the best combustion values.

♦ The atomizing device can be removed without removing the burner from the boiler, which facilitates maintenance.

♦ Manual air flow regulation.

♦ One flange and one insulating seal for boiler fixing.

♦ Combustion air inlet with air flow regulation.

♦ Sliding boiler coupling flange to adapt to the head protrusion of various types of boilers.

♦ Single-phase electric motor runs the fan.

♦ Flame presence check by ionization electrode.

♦ Electrical equipment protection level IP40.

Question 5-FAQ

Q1: What types of fuel does this burner support? Is it easy to switch between fuels?

A: The BNG400FC is designed as a multi-fuel burner and supports:
Natural Gas (NG)
Propane (LP)
Propane Air Mix (LA)
Town Gas (TG)
Digester Gas / Biogas (DG)
Fuel switching typically requires replacing or adjusting the gas train components, nozzles, and reconfiguring control parameters. It is recommended that this be performed by qualified technicians to ensure safety and optimal performance.

Q2: It has a wide power range (400–3950 kW). How do I select the right power for my equipment?

A: Power selection depends on your specific thermal load requirements. Key factors to calculate include:
The heat demand of your application (e.g., boiler evaporation rate, furnace heating curve).
The calorific value of your fuel.
The overall system thermal efficiency.
We recommend consulting our engineers. Please provide your equipment model, process temperature, and required output for an economical and efficient power recommendation.

Q3: What does "Modulating Control" mean for this burner? What are the benefits?

A: "Modulating Control" means the burner's output can be continuously and infinitely varied between its minimum and maximum firing rates (as opposed to simple on/off or high/low-stage operation).
Key Benefits:
Energy Savings: Precisely matches actual heat demand, avoiding energy waste.
Stable Temperature: Provides smooth thermal output, improving process quality.
Equipment Longevity: Reduces thermal cycling and mechanical wear caused by frequent starts and stops.

Q4: The burner's matching motor power is 9 kW. Is this consumption high?

A: For a thermal device with a maximum output of 3950 kW, a 9 kW combustion air fan motor's power consumption is relatively low and indicates an efficient design. This motor drives the fan, and its consumption is factored into the system's overall efficiency calculation.
