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

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.
