FBR Gas Burner Buyer's Guide: Types, Specs & Selection for Indonesia
What Is an FBR Gas Burner?
FBR gas burners are Italian-engineered two-stage combustion units designed for industrial boilers, furnaces, and thermal processing equipment across Indonesia. As an authorized FBR distributor, 3G Electric supplies complete modulating burner systems with electronic flame supervision, gas trains, and controls—all certified for low-NOx operation (Class 3–4). Thermal output ranges from 192 kW for small commercial boilers to 6395 kW for large-scale industrial facilities. FBR burners are standard-fit equipment in paper mills, textile plants, food processing, and district heating networks across Sumatra, Java, and Kalimantan.
How FBR Gas Burners Work
FBR burners employ a two-stage ignition sequence. At startup, a pilot flame (ignition transformer + electrode) establishes combustion; once stable, the main gas valve opens and the air fan ramps to full capacity. Electronic or mechanical modulation (cam-based) adjusts fuel flow and air damper position to maintain setpoint boiler pressure or temperature, reducing energy waste and NOx emissions. A flame monitor (UV or ionization cell) continuously verifies safe operation; loss of flame triggers automatic shutdown within 4 seconds. The burner head (nozzle DN250–DN560) atomizes and mixes gas with forced air at 1.0–1.5 bar gauge.

Types & Industrial Applications in Indonesia
FBR manufactures three principal gas burner classes:
- Two-Stage Manual (P 100/2) — Compact, single-phase option for small boilers (192–1163 kW). Ideal for commercial facilities, small district heating, backup power plants. Low-cost entry point.
- Two-Stage Modulating with Mechanical Cam (P 250/M) — Burner body + separate mechanical controller adjusts fuel & air continuously. 372–2209 kW range. Preferred for paper mills, textile processing, rubber vulcanization.
- Two-Stage Modulating with Electronic Control (P 550/M, KN 550/M) — Full PLC interface, soft-start fan, precision NOx control. 750–6395 kW. Used in large boiler plants, petrochemical preheating, shipboard auxiliary systems.
How to Select the Right FBR Gas Burner
- Calculate Boiler Heat Load — Multiply: (kg/hr steam required) × (specific enthalpy rise, ~2640 kJ/kg for saturated steam). Divide by efficiency (90–95%) to get burner kW. Add 10% margin for peak demand.
- Verify Gas Supply Pressure — Most FBR units operate at 1.0–1.5 bar gauge inlet. Check your gas distributor (PGN Jakarta, PGN Medan, LPG bottled supply) pressure regulation. Undersized gas line = poor modulation.
- Confirm Electrical Supply — Small models accept 1–3 phase 380 VAC/50 Hz. Large units (P 550/M, KN 550/M) require 3-phase 380 VAC with 32 A minimum circuit. Verify earthing & UPS backup (for flame sensors).
- Check Emission Compliance — Indonesia environmental ministry (PLN, local air quality) may require Class 3 or Class 4 (ultra-low NOx <150 mg/Nm³). Verify permit requirements before ordering.
- Plan Installation Space — Large units (KN 550/M: 341 kg) require reinforced burner block, flange connection, and 1 m clearance for service access. Surabaya and Jakarta facilities often have retrofit constraints.
Frequently Asked Questions
Q: Can FBR gas burners run on LPG, CNG, or piped natural gas?
A: Yes. FBR supplies dual-fuel variants (GPL, CNG ready). Specify fuel type at order; requires different gas train pressure regulators and orifice sizing. PGN natural gas is standard in Java; LPG common in Sumatra and eastern regions.
Q: What is the minimum thermal input to avoid flame instability?
A: FBR two-stage burners (modulating) have a 3:1 turndown ratio. Minimum stable load is ~33% rated kW. Below that, use on/off (non-modulating) control. For 1163 kW unit (P 100/2), minimum is ~387 kW.
Q: How often must FBR burners be serviced?
A: Annual inspection (flame electrode cleaning, gas valve testing, air intake filter) is mandatory. Every 3 years: full overhaul of ignition transformer and valve seals. Neglect voids warranty and creates fire risk.
Q: Where can I buy genuine FBR parts in Indonesia?
A: 3G Electric stocks OEM FBR nozzles, transformers, gas trains, and replacement blocks. We hold 874+ burner components and deliver to Jakarta, Surabaya, Batam, and regional ports within 5–7 working days with full import documentation and English technical support.
