Supplier shall provide complete electrical load and wiring information.

Gas Train The complete gas train shall be supplied with the burner and shall include, as a minimum: Manual isolation valve Gas filter Pressure regulator Gas pressure gauge Minimum/maximum gas pressure switches Safety shut-off valves Automatic/modulating gas control valve

Combustion Air & Modulation The burner shall be equipped with a forced-draft fan and automatic air-control system. Fuel and combustion air shall be automatically adjusted according to the required firing rate. The system shall provide: Low Fire → Progressive Firing → Modulating Operation → High Fire

Ignition & Flame Safety The burner shall include: Automatic ignition system Ignition transformer/electrode Flame detector Flame failure protection Automatic fuel shut-off Failure of flame establishment or flame loss during operation shall automatically shut off the fuel supply.

Burner Management & Control The burner shall include an automatic Burner Management System (BMS) providing: Pre-purge Automatic ignition Flame verification Firing-rate control Automatic shutdown Post-purge Alarm and lockout indication The burner shall be compatible with the control system of the associated boiler/heater.

Safety Protection Automatic shutdown shall be provided for, as applicable: Flame failure Low/high gas pressure Combustion air failure Fan failure Emergency stop Control system fault High process temperature/pressure Safety shut-off valves shall be fail-safe.

Materials & Environmental Conditions The burner shall be suitable for outdoor oil & gas service. Unless otherwise specified: Ambient temperature: −40°C to +50°C Industrial/oil & gas environment Corrosion-resistant external coating Heat-resistant combustion head and flame components

Inspection & Testing The Supplier shall perform, as a minimum: Visual and dimensional inspection Gas tightness test Ignition test Flame failure test Safety interlock test BMS functional test Minimum/maximum firing test Modulation test A Factory Acceptance Test (FAT) report shall be provided.

Documentation & Spare Parts Supplier shall provide: Burner datasheet GA drawing Gas train drawing P&ID Electrical/wiring diagram Control philosophy BMS/Cause & Effect Fuel consumption data Performance test report Certificates Operation & Maintenance Manual Recommended spare parts list for 2 years
