Palm oil production involves multiple stages, including sterilizing fresh fruit bunches, pressing, clarification, refining, and fractionation. Each step relies on a continuous and stable supply of saturated steam. The Indonesian customer operates in a region where production loads vary with harvest seasons, leading to frequent changes in steam demand. Under these conditions, the customer required a 15 t/h Coal-Fired Steam Boiler with robust capacity, strong adaptability to different coal grades, and a low operation and maintenance burden.

ZOZEN SZL series 15 t/h Coal-Fired Steam Boiler

After comprehensive technical evaluation, the customer selected the ZOZEN SZL series 15 t/h Coal-Fired Steam Boiler. This series is a horizontal double-drum, chain-grate water-tube boiler with a longitudinal arrangement and a furnace lined with closely spaced water-cooled wall tubes. The design is well suited to industrial applications requiring continuous steam supply under variable operating conditions.

Key technical characteristics include:

Rated steam capacity: 15 tons per hour, sufficient to meet peak steam demand during high-load production periods

Boiler type: SZL series horizontal double-drum water-tube boiler

Combustion system: Chain grate with independent air chambers

Fuel adaptability: Suitable for bituminous coal, lean coal, and anthracite

Thermal performance: Boiler thermal efficiency of 81% or higher under design conditions

This configuration allows the 15 t/h Coal-Fired Steam Boiler to maintain stable performance even when coal properties fluctuate, supporting consistent palm oil processing operations.

Technical advantages for variable coal and load conditions

One of the core strengths of the SZL series 15 t/h Coal-Fired Steam Boiler lies in its broad fuel adaptability. The chain grate combined with independent air chambers enables zoned and adjustable air distribution along the grate. This makes it possible to match combustion conditions to different coal characteristics, improving stability and reducing sensitivity to fuel variability.

Independent air chambers allow more precise control of primary and secondary air, supporting better combustion organization. Together with appropriate grate speed adjustment and fuel bed thickness control, the furnace creates favorable conditions for more complete coal combustion, reducing unburned losses.

In addition, the closely spaced water-cooled wall tubes significantly increase the radiant heat transfer area in the furnace. This design enhances heat absorption and contributes to steady thermal efficiency. As a result, the 15 t/h Coal-Fired Steam Boiler delivers reliable steam output while helping the customer improve specific energy consumption.

Operation, maintenance, and overseas service support

Ease of operation is another important advantage of the SZL series 15 t/h Coal-Fired Steam Boiler. An advanced control system improves automation of fuel feeding, ash removal, and slag discharge, reducing manual intervention and simplifying operator training and shift handover. This is particularly valuable for overseas projects where workforce turnover and training efficiency are critical.

ZOZEN Boiler has long focused on overseas markets and has accumulated extensive experience in Southeast Asia. For this Indonesia project, ZOZEN provided end-to-end support, including solution design, export packaging, on-site installation guidance, and operation training. This comprehensive service approach ensured smooth delivery, commissioning, and stable long-term operation of the 15 t/h Coal-Fired Steam Boiler.
