A fuel oil and gas steam generator is a device that uses fuel oil (such as diesel, heavy oil) or gas (such as natural gas, liquefied petroleum gas, biogas) as fuel, generates heat energy through combustion and heats water to generate steam. It has the characteristics of high thermal efficiency, clean combustion and flexible fuel selection, and is widely used in scenarios with high requirements for energy stability and environmental protection.

Working principle : Fuel or gas is mixed with air in the burner and fully burned, releasing high-temperature heat energy. Flames and high-temperature flue gas pass through the furnace, fire pipe or water pipe system to transfer heat to water. Water is vaporized by heat, and dry steam is output after steam-water separation. The pressure is adjusted by the control system. Some models are equipped with condensers or economizers to recover waste heat from flue gas and improve thermal efficiency.

Core Advantages

High thermal efficiency: The thermal efficiency of gas-fired type can reach 92%-95%, and that of oil-fired type is about 85%-90%, with significant energy-saving effect.

Clean and environmentally friendly: Gas combustion emits almost no particulate matter, and sulfide and nitrogen oxide (NOx) can be controlled through technology (such as full premixed combustion and FGR flue gas recirculation).

Fast start and stop: Automated combustion control, fast steam output response, suitable for intermittent steam demand.

Fuel flexibility: Supports multi-fuel switching (such as oil and gas dual-fuel models) to adapt to fluctuations in energy prices.

Small footprint: Modular design, no need for complicated fuel storage (especially gas type).
