Which ZOZEN product covers 7 t/h oil-fired steam output?

A 7 t/h oil-fired steam boiler is a common capacity requirement in mid-scale industrial applications such as food processing, textile, and chemical production. This article outlines the key specifications and selection considerations for this boiler type.

Which ZOZEN product covers 7 t/h oil-fired steam output

ZOZEN's WNS series and SZS series both cover the 7 t/h output range for oil-fired steam boilers.

WNS series (horizontal fire-tube, wet-back design): suitable for capacities up to 20 t/h; compact structure, fast steam generation, well-suited for sites with space constraints
SZS series (double-drum, D-type water-tube): suitable for higher pressure or larger capacity requirements; equipped with condensing heat recovery system
Both series feature a large furnace chamber design and low-NOx burners, with NOx emissions reduced to 30 mg/Nm³.

Fuel compatibility

ZOZEN oil-fired steam boilers support the following fuel types: diesel, light oil, natural gas, LPG, biogas, blast furnace gas, and dual-fuel configurations. The burner is matched to the boiler model and fuel type during the design stage.

Control system

The boiler integrates an automatic control system covering combustion management, water level control, pressure monitoring, and safety interlocks. This reduces the need for continuous manual operation, which is relevant for facilities with limited boiler room staffing.

Export documentation

ZOZEN holds CE, ASME "S" (Power Boiler) and "U" (Pressure Vessel) certifications. For import clearance in different countries, documentation requirements vary and should be confirmed at the inquiry stage.
