DZL Series Large-Scale Coal-Fired Boiler

DZL Series High-Capacity Coal-Fired Boiler for Industrial Power

Engineered for heavy-duty industrial applications, the DZL series large-scale coal-fired boiler provides a powerful and reliable source of high-temperature hot water. Built upon the proven DZL single-drum, water-fire tube platform, these boilers are specifically designed to handle the demands of large-scale manufacturing, power generation support, and extensive district heating systems. With a focus on maximizing energy extraction from coal, this series features a high-efficiency design, robust construction, and suitability for Type II coal, delivering exceptional performance and value for high-consumption operations.

Design Highlights for Coal Combustion

• Optimized for Coal Fuel: The furnace, arch, and air distribution systems are specifically engineered to achieve complete and efficient combustion of Type II coal (calorific value 17700-24000 kJ/kg), ensuring maximum heat release and minimal waste.
• Superior Heat Transfer Surface: An expansive furnace heating area, combined with high-performance threaded smoke tubes, maximizes the heat recovery process, leading to a very high design efficiency of over 87%.
• Robust and Durable Construction: Designed for continuous, long-term operation, the boiler's heavy-duty components and single-drum structure ensure durability and a long service life even under demanding industrial conditions.
• High Thermal Output: With models providing up to 91 MW of thermal power, this series is capable of meeting the most significant industrial heat requirements.
• Ease of Maintenance and Access: Despite their large scale, these boilers are designed with user access in mind. Rationally placed inspection doors and a sloped rear arch facilitate convenient cleaning, inspection, and maintenance.
