Industrial Oil Burner BNL5

Question 1-Product Description

SHORT DESCRIPTION

1. Fuel Adaptability

   • Runs on diesel oil, which is clean, easy to store, and suitable for locations without natural gas pipelines or requiring mobile heat supply.

   • Simple fuel system with no complex pretreatment (compared to heavy oil).

2. Moderate Power Range

   • Power output range: 24-66 kW, suitable for small to medium-scale heating demands.

   • Fuel modulation ratio ≈ 1:2.75 (2-5.5 kg/h), allowing adaptation to partial load changes.

3. Simple and Reliable Control

   • Single-stage (on/off) fire control: Simple structure, low failure rate, easy maintenance.

   • Suitable for continuous heating applications where precise temperature control (±5°C) is not critical.

4. Low Pressure Requirement

   • Combustion chamber pressure only 2.5 mbar, compatible with most conventional boiler designs due to low back-pressure demand.

5. Universal Power Supply

   • Operates on 220V/50Hz single-phase AC, eliminating the need for three-phase industrial power and enabling flexible installation.

Question 5-FAQ

Q1: What type of boiler is this burner suitable for?
A: The BNL5 is suitable for small steam boilers, hot water boilers, or hot air boilers with a thermal power requirement between 24-66 kW. For specific selection, ensure the boiler's design back pressure does not exceed the burner's allowable limit of 2.5 mbar and verify compatibility with the boiler's connection dimensions. It is recommended to consult the equipment supplier for final confirmation.

Q2: What is its noise level?
A: Diesel burners generate noise from the fan and combustion during operation. The BNL5, being a small-to-medium power model, has a controllable noise level. If installed in noise-sensitive areas (e.g., near residential areas, indoors), noise reduction measures are recommended, such as installing an acoustic enclosure for the burner or using silenced air intake ducts.

Q3: What does "One stage fire" control mean? What are its advantages and disadvantages?
A: "One stage fire" means the burner operates in only two states: fully on and completely off, with no ability to modulate the flame.

• Advantages: Simple structure, low cost, low failure rate, easy maintenance.

• Disadvantages: Causes relatively significant fluctuations in boiler temperature or pressure (frequent cycling on and off) around the setpoint, resulting in relatively lower thermal efficiency. It is unsuitable for processes requiring extremely precise temperature control.

• Comparison: For smoother temperature control and energy savings, consider "two-stage" or "proportional modulation" burners.
