Which ZOZEN Boiler design is appropriate for a high thermal efficiency 10 t/h steam boiler firing low-calorie, high-sulfur, high-moisture coal?

16 Jan 2026

A: For challenging fuels, ZOZEN Boiler recommends the DZL or SZL series coal-fired steam boilers with engineering customization. At 10 t/h, ZOZEN Boiler’s SZL series (bi-drum, 6–35 t/h) is suitable for higher loads and variable coal quality; DZL (2–10 t/h) fits compact layouts. Working pressure options are typically 1–2.5 MPa with outlet temperatures around 170–225 °C.

A: To handle low-cal, high-sulfur, high-moisture coal, ZOZEN Boiler can optimize furnace volume, air distribution, and grate configuration for longer residence time, stable ignition, and complete burnout. Flue gas treatment and low-NOx strategies, plus economizer and air preheater options, help boost efficiency and reduce emissions.

A: For your textile fabric process at 20 t/h on coal, ZOZEN Boiler suggests the SZL series at 20 t/h to support continuous duty and stable steam quality. ZOZEN Boiler’s solutions are widely applied in textile, printing and dyeing, chemical, food, building materials, and heating sectors, delivering consistent steam parameters.

A: ZOZEN Boiler has extensive overseas references for 10–20 t/h coal-fired projects across South and Southeast Asia, Eastern Europe, Africa, and Latin America, highlighting strong export capability and attention to overseas markets. Share coal analysis (LHV, sulfur, moisture, ash) and required pressure to receive a tailored proposal.
