Single Burner Buyers Guide Philippines | Selection & Sizing
What Is a Single Burner?
A single burner is a self-contained combustion unit that mixes fuel (gas, oil, or dual-fuel) with air and ignites it in a controlled flame. It is the core heat source for industrial boilers, hot oil heaters, and air heaters throughout the Philippines – from food processing plants in Laguna to garment factories in Cavite. While the burner itself must be sourced from a combustion specialist (e.g., Riello, Honeywell, or Suntec), 3G Electric complements these systems with essential cable management from PANDUIT and LEGRAND for control wiring, and adjustable work platforms from TRI-ARC and COTTERMAN for safe maintenance access.
How a Single Burner Works
Fuel enters at a regulated pressure (typically 1.0–3.5 bar for gas, 7–20 bar for oil) through a nozzle or spud. A combustion air fan supplies oxidant, and an ignition transformer (10–20 kV) sparks the mixture. A flame-sensing electrode (UV or ionization) confirms ignition and signals the controller. Most industrial single burners use modulating control (PID signal from a process controller) to vary firing rate between 20 % and 100 % of rated capacity.
Key Specifications (Typical Range)
| Parameter | Typical Range |
|---|---|
| Firing rate (kW) | 50 – 1,200 kW |
| Fuel supply pressure (gas) | 1.0 – 3.5 bar |
| Combustion air pressure | 3 – 12 mbar |
| Control voltage | 24 VDC / 230 VAC |
| Flame sensor type | UV cell / Ionization rod |
| Ignition transformer output | 10 – 20 kV |
| Max flue gas temperature | 250 – 350 °C |
According to Riello RDB Sizing Guide, 2023: “Select the burner firing rate at least 15% above the maximum load to avoid short‑cycling; always verify that the back‑pressure in the combustion chamber does not exceed 2 mbar for forced‑draught burners.”
Types & Applications in the Philippines
- On/Off single burner – For packaged steam boilers up to 300 kW. Simple, low cost, but less efficient under partial loads.
- High/Low/Off single burner – Common in oil‑fired dryers and batch process heaters. Two firing steps reduce thermal shock.
- Modulating single burner – Preferred for continuous processes (e.g., poultry rendering, laundry steam). Firing rate adjusts smoothly, saving 10–15% fuel vs. on/off.
- Dual‑fuel single burner – Switches between natural gas and diesel/LPG. Essential when fuel supply is uncertain – frequently specified in Philippine special economic zones.
How to Choose the Right Single Burner (Selection Criteria)
- Determine heat load (kW or MBH) – Calculate the energy required by your boiler or process. Use the formula: kW = (mass flow × ΔT × specific heat) / 3,600. Always include a 15–20% safety margin.
- Select fuel type and pressure – Natural gas requires 1.0–3.5 bar. If using LPG, ensure vaporiser capacity matches demand. Heavy oil (C-grade) needs pre‑heating to 80–110 °C and higher pump pressure.
- Check combustion air availability – For forced‑draught burners, verify that the boiler’s chamber back‑pressure is ≤2.0 mbar at full fire. Install PANDUIT T70OCIW 90° External Elbow for routing control cables cleanly from the burner panel.
- Control system compatibility – Most modern burners accept a 4–20 mA or 0–10 VDC input from a PLC. Ensure your system matches the flame safety controller’s requirements (normally 24 VDC).
- Plan for maintenance access – A TRI-ARC Adjustable Height Work Platform (max 14 in.) or COTTERMAN Work Platform (36 in. depth) provides safe standing height for burner inspections.
- Consider local emissions regulations – Philippine DENR limits NOₓ to 500 mg/Nm³ for natural‑gas burners (DAO 2000‑81). Low‑NOₓ heads may require 3–5% excess O₂ control.

Frequently Asked Questions
Q: How do I size a single burner for my boiler in the Philippines?
A: Calculate your boiler’s heat load in kW by multiplying steam output (kg/h) by enthalpy difference (≈2,700 kJ/kg) and dividing by 3,600. Then choose a burner with a firing rate at least 20% higher.
Q: Where can I buy genuine single burner parts in the Philippines?
A: 3G Electric does not directly supply burner components, but we partner with leading distributors for Riello, Honeywell, and Suntec. Contact us for sourcing assistance and we’ll connect you with the right supplier.
Q: Can I use a LEGRAND raceway elbow for burner control cables?
A: Yes. The LEGRAND Steel 90° Flat Elbow (Series 500) is ideal for routing low‑voltage control wires from the burner to the boiler control panel in surface‑mounted raceways.
Q: What is the typical control voltage for industrial single burners?
A: Most modern burners operate on 24 VDC for safety circuits and 230 VAC for the fan motor. Verify your existing control panel before ordering.
Q: Do I need a work platform for burner maintenance?
A: For burners mounted above 1.5 m, a TRI-ARC Adjustable Height Work Platform (max 14 in.) provides a safe, stable surface. Ensure the platform’s load rating exceeds your personnel weight.
Q: How often should a single burner be serviced in tropical climates?
A: In the Philippines’ high‑humidity environment, inspect the ignition electrodes, flame sensor, and air filter every 3 months. Schedule a full combustion analysis twice a year.
Q: What fuel pressure is needed for natural‑gas single burners?
A: Typically 1.0–3.5 bar at the burner inlet. If your supply pressure is lower, a booster compressor may be required – 3G Electric can quote pressure‑regulating skids.
