Harbin Boiler Fuel Manufacturer Reminds You: Gas-fired boilers mainly 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-fired boilers in terms of equipment investment and operational economy can be fully demonstrated. The other is the mixed combustion mode, which features two combustion systems: gas-oil and gas-coal. The boiler can combust coal gas alone, another fuel alone, or both fuels mixed together. This is also referred to as a dual-fuel burner.

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