140kw 100k 220v/50HZ methane flame propane butane fuel gas burner for boiler with control box

The burner is compatible with methane (natural gas), propane and butane. Switching fuels may require nozzle or pressure adjustments — consult the supplier or a qualified technician for tuning and conversion parts.

The unit requires 220 V, 50 Hz mains power as specified. The control box and electric servomotor run from this supply. Ensure a stable 220 V supply and appropriate circuit protection.

Thermal output is 70 kW (50k listed in model name). It is designed for industrial boilers, steam generation, plant heating and other industrial applications requiring efficient gas combustion.

The burner supports one-stage or two-stage operation and manual flow adjustment for single-stage use. It uses an electric servomotor for air flow regulation; for full modulating control you should request compatible control options from the supplier.

The burner includes flame presence monitoring via an ionisation electrode. The control box handles ignition and safety shutoff on flame failure. Additional safety devices (gas shutoff valves, pressure switches, CO detectors) should be installed per local regulations.

Yes — a control box is included. It provides ignition control, flame detection interface, servomotor drive for air flow and basic burner sequencing. For detailed I/O, wiring diagrams and PLC integration options, request the control box manual from the supplier.

IP40 provides protection against solid objects greater than 1 mm but offers no protection against water. Install the burner and control box in a dry, sheltered environment or provide additional weatherproof enclosures if exposed to moisture.

Air-gas mixing is performed at the blast-pipe (air-gas mixing at the blast-pipe) to promote optimal combustion. The electric servomotor adjusts air flow to maintain correct air/fuel ratio when set up properly.

Regular maintenance includes visual checks, cleaning the removable atomisation (nozzle) unit, inspecting and cleaning the ionisation electrode, checking seals and gaskets, verifying gas connections and pressures, and annual professional servicing. Always isolate power and gas before performing maintenance.

The burner includes a flange and insulating seal for installation. Verify flange dimensions and bolt pattern against the boiler's burner plate; adapters may be required if patterns differ.

Yes — the product listing indicates air freight. The unit will be shipped empty of fuel and prepared per air transport packaging rules. Buyers should confirm specific air-cargo regulations, import restrictions and any documentation required by the carrier or destination country.

Certifications (CE, ISO, etc.) are not listed in the product description. Request copies of applicable conformity certificates, test reports and compliance documentation from the seller prior to purchase to ensure the unit meets local regulatory requirements.

Correct gas pressure and burner tuning are critical for safe, efficient operation. Commissioning should be performed by a qualified technician who will set gas pressure, adjust air/fuel ratio, check combustion efficiency and safety shutdowns. Ask the supplier for recommended gas inlet pressures and commissioning procedures.

Common service parts such as atomisation units (nozzles), ionisation electrodes, gaskets and servomotor components are typically available. Contact the supplier for part numbers, availability and lead times.

Warranty and support terms are not specified in the description. Contact the seller for details on warranty period, coverage, spare-parts support and after-sales technical assistance before purchasing.
