Harbin Boiler Fuel Manufacturer Reminds You: Gas boilers primarily have two modes of combustion. One is the dedicated combustion mode, where the boiler is equipped only with a gas combustion system. In this case, the advantages of gas boilers in terms of equipment investment and operational economy can be fully demonstrated. The other is the mixed combustion mode, which is equipped with two combustion systems: gas-oil and gas-coal. The boiler can combust gas alone, another fuel alone, or a mix of both, and is also referred to as a dual-fuel burner.

A dual-fuel burner features both gas and oil nozzles within the same burner. The air regulator, flame stabilizer, ignition device, and flame monitoring system of the control section must be suitable for both fuel types.
