Flame Scanners & Burner Management

Product Overview

Safe Combustion — Every Time

Flame scanners are a critical safety layer in any fired plant. Hi-Tech Automation supplies, installs, and commissions ATEX-certified UV and IR flame detectors along with complete Burner Management System (BMS) panels that comply with NFPA 85 and IEC 61511 safety standards.

We integrate flame monitoring directly into your DCS or standalone PLC-based BMS — providing automated burner sequencing, safe start/shutdown interlocks, and continuous flame failure alarm with fast response times under 1 second.

ATEX Zone 1 & Zone 2 rated detectors
SIL-2 rated BMS safety logic
Multi-burner systems with individual UV/IR heads
Auto-purge and safe start sequencing
Integration with DCS historian and alarm systems

Product Range

Types of Flame Detection

🔵

UV Flame Scanners

Ultraviolet-based detectors for gas and light oil flames. Fast response (<0.5 s), resistant to background IR radiation, ideal for gas burners.

Spectral range: 190–280 nm
Response time: <0.5 s
Self-check function

🔴

IR Flame Scanners

Infrared detectors for oil and coal flames. Suitable for heavy fuel oil, coal dust, and biomass combustion — works in high dust / smoke environments.

Spectral range: 700–1100 nm
Response time: <1 s
Sight pipe compatible

Features

Complete BMS & Flame Safety Capabilities

NFPA 85 Compliant BMS

Automated burner management logic covering purge, ignition, run, and safe shutdown per NFPA 85 and IEC standards.

SIL-2 Safety Logic

Safety Instrumented Function (SIF) designed to SIL-2 per IEC 61511 — includes SIL verification reports and proof-test procedures.

ATEX / IECEx Certified

All detectors certified for use in Zone 1 and Zone 2 hazardous areas — suitable for gas, oil, and petrochemical plants.

Self-Diagnostics

Continuous automatic self-test function detects scanner failure or sighting window contamination without process interruption.

Multi-Burner Control

Independent management of each burner with individual ignitor control, fuel valve sequencing, and flame presence monitoring.

DCS / PLC Integration

4–20 mA, HART, Modbus RTU, or Profibus DP communication for seamless integration into existing plant control systems.

High-Temp Operation

Detectors rated for ambient temperatures up to 70°C — with optional air/water purge cooling assemblies for extreme environments.

AMC & Spare Parts

Annual Maintenance Contracts with calibration, replacement heads, and 24×7 emergency support for critical fired equipment.

Applications

Where We Deploy Flame Safety Systems

Power Plant Boilers

Coal, oil, and gas-fired utility boilers with multi-burner BMS panels, ignitor management, and master fuel trip interlocks.

Refinery Heaters

Process fired heaters, CDU/VDU furnaces, and reformer heaters requiring ATEX-rated detection in hazardous areas.

Sugar & Distillery Boilers

Bagasse and multi-fuel boilers requiring robust IR detection and BMS logic for varying fuel moisture content.

Chemical & Thermal Plants

Thermic fluid heaters, reformers, and incinerators with gas or LPG firing — requiring SIL-2 BMS protection.

Paper & Textile

Hogged fuel and natural gas boilers in pulp and paper mills — UV/IR combination scanners for mixed fuel combustion.

Oil & Gas Flare Systems

Flare tip pilots and combustion monitoring with continuous UV detection — ensuring pilot presence in remote flare stacks.
