Which ZOZEN boiler models are popular as a steam boiler for palm oil industry applications?

For palm oil mills, ZOZEN’s SZL series biomass-fired steam boiler is a standout due to its adaptability to PKS, EFB, and fiber blends.

The SZL uses a modular shop-assembled design, membrane water wall structure, and optimized furnace arch to improve combustion of high-volatile, high-ash fuels common in palm residues. For larger capacities or higher efficiency targets, the DHL series corner-tube biomass boiler offers better load response and lower auxiliary power.

Where gaseous or liquid fuels are preferred—often for start-up or peak shaving—ZOZEN’s SZS series gas/oil-fired water-tube boiler delivers high steam quality, low NOx, and compact footprint; WNS series suits small-to-medium capacities with quick installation. In cogeneration scenarios, ZOZEN can pair high-pressure steam boilers with backpressure turbines to supply both process steam and electricity.

Optional systems include multi-cyclone plus baghouse or wet scrubbers for particulate control, fuel handling lines for PKS/EFB, flue gas economizers, air preheaters, and condensate recovery packages. Model selection is based on capacity (typically 10–75 t/h for mills), steam pressure/temperature, available fuels, and emission limits.
