Selecting a 10-20 Ton Coal Steam Boiler for Textile Industry with High Moisture Coal

Q: I need a steam boiler with high thermal efficiency, 10 t/h or 20 t/h. The fuel is coal with low calories, high sulfur, and high moisture. Kindly advise which design is appropriate for the textile fabric process.

A:
The textile fabric process requires a stable and continuous steam supply. For a capacity of 10 t/h to 20 t/h using coal with low calories, high sulfur, and high moisture, selecting the right boiler design is critical to prevent corrosion and ensure efficiency.

For the 10 t/h requirement, we recommend the ZOZEN SZL series double-drum chain grate boiler. To handle high moisture and low calorie coal, we will customize the furnace arch and air distribution system. A longer grate and specialized front arch help preheat and dry the damp coal before combustion, ensuring it burns fully.

For the 20 t/h requirement, or if the coal quality is particularly poor, the ZOZEN DHX series Circulating Fluidized Bed (CFB) boiler is the ideal choice. The CFB technology is renowned for its broad fuel adaptability. It can efficiently burn low-grade fuels like high sulfur and high moisture coal. Moreover, the DHX series allows for in-furnace desulfurization by adding limestone, which effectively neutralizes the sulfur, protecting the boiler from corrosion and meeting environmental standards.

Both the SZL and DHX series are robust solutions for the textile industry, providing the high thermal efficiency and steam quality needed for dyeing and drying processes.
