Harbin Boiler Fuel Manufacturer Reminds You: Gas boilers mainly have two types of combustion methods. One is the dedicated combustion method, 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 method, which is equipped with two combustion systems: gas-oil and gas-coal. The boiler can combust natural gas alone, another fuel alone, or a mixture of both, which is also known as a dual-fuel burner.

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