Gas oil fired steam boilers play a crucial role in various industrial applications, meeting the demand for reliable and efficient steam generation. At ZOZEN, we take pride in offering gas oil fired steam boilers that stand out with their safety, stability, high efficiency, energy conservation, and environmental friendliness. As a trusted supplier, we provide top-quality products that cater to your needs.

ZOZEN’s Gas Oil Fired Steam Boilers
ZOZEN offers three series of gas oil fired steam boilers: the WNS series condensing horizontal internal combustion boilers, the SZS series condensing double-drum vertical boilers, and the ZZ series medium-temperature and medium-pressure gas oil fired steam boilers. All three series feature large furnace designs, achieving thermal efficiencies of over 98% and NOx emissions as low as 30mg/Nm3. They can accommodate a wide range of fuels, including natural gas, coke oven gas, biogas, diesel, heavy oil, light oil, and residual oil. The front and rear smoke boxes adopt ZOZEN’s patented sealing structure, ensuring no smoke leakage and offering fully automatic and safe operation.

WNS Series Gas Oil Fired Steam Boiler
Working pressure ranges from 0.7 to 2 MPa, with a thermal capacity of 1-20t/h.
Energy-saving devices and condensers utilize flue gas heat, raising the inlet water temperature and reducing the exhaust gas temperature, resulting in a boiler thermal efficiency of up to 98%.
When using natural gas as fuel, the gas consumption per ton of steam is less than 72 cubic meters.
With proper operation according to the user manual, the boiler can have a service life of up to 20 years.

SZS Series Gas Oil Fired Steam Boiler
Working pressure ranges from 1.25 to 5.4 MPa, with a thermal capacity of 2-110t/h for steam boilers.
The narrow spaced membrane water-cooled wall ensures excellent gas tightness, reducing heat loss and improving boiler thermal efficiency.
High-quality alumina silicate fiber and refractory mortar insulation are used to keep the furnace temperature below 45°C, effectively controlling heat loss.
ZOZEN has designed a unique self-supporting steel frame, minimizing the connection points between the frame and drum, eliminating other connections, and bringing the outer surface temperature of the furnace close to ambient temperature, thus improving overall thermal efficiency.

ZZ Series Medium-Temperature and Medium-Pressure Gas Oil Fired Steam Boiler
Working pressure ranges from 2.5 to 5.4 MPa, with a thermal capacity of 20-130t/h.
Equipped with safety devices such as explosion-proof doors and flame detectors, the boiler ensures automatic water level regulation, high and low water level alarms, overpressure alarms, and shutdown in case of extremely low water level.
Fully automatic and safe operation: Boiler IoT (Internet of Things) technology, remote control, and expert management.
High-quality steam output with proper steam drum size and steam-water separator configuration, minimizing carryover and ensuring high-quality steam.
