Different from coal-fired boilers, oil fired steam boilers use burners to inject fuel into the boiler hearth, and use fire chambers to burn without using grate facilities. Since the oil-fired steam boiler does not produce fuel ash after combustion, the oil-fired steam boiler does not need slag discharge facilities. If the oil and gas injected into the furnace is mixed or extinguished with air within a certain range, it is easy to explode. Therefore, all oil-fired steam boilers need to adopt automatic combustion and control systems. The oil fired steam boilers have compact structure. The small boiler body and its ventilation, water supply, control and auxiliary equipment are all set on a chassis, and large and medium-sized boilers can also be assembled and delivered from the factory.

The popular oil fired steam boilers are ZOZEN SZS series and WNS series condensing oil-fired steam boilers, which have the characteristics of safety, reliability, high efficiency, energy saving, environmental protection, convenient maintenance, automatic intelligent control and so on.
Compared with the traditional oil-fired steam boiler, its thermal efficiency is higher, and it can realize the low nitrogen emission of NOx less than 30 mg/nm. It has the obvious advantages of high efficiency and low emission, and has a good market reputation.
WNS series energy-saving oil fired steam boilers
Capacity: 1-20t/h
Pressure: 0.7-2.0Mpa
Components: boiler shell, tubesheet, furnace liner and smoke pipe;
SZS series energy-saving oil fired steam boilers
Capacity: 20-110t/h
pressure: 0.7-1.25MPa
Components: drum, water wall, boiler tube bundle, serpentine tube and header;
In addition to considering the principle of combining technology with economy, the selection of oil fired steam boilers should also consider the owner's intention comprehensively, and combine the opinions of environmental protection, fire protection and labor departments, with safety and environmental protection as the priority.
Here are a few selection principles to pay attention to:
1. The boiler should be automatic operation, safe and secure, with reliable automatic control and protection device.
2. Choose boiler manufacturers with good reputation and good after-sales service.
3. The boiler performance should be consistent with the user's hot and steam consumption characteristics, with good adaptability. When the user's load changes greatly, the sensitivity should be high, the tracking should be fast and the pressure should be stable.
4. Depending on the boiler layout position and requirements, choose vertical or horizontal boiler.
5. Users are required to provide load curves in order to verify the output and performance of the selected boiler.
