The Aix fixed-grate coal-fired hot water boiler features a water-fire tube structure with a two-wing flue duct design, incorporating a spacious furnace and combustion chamber. High-efficiency threaded flue tubes are integrated into the boiler drum, reducing the heating time by approximately one-third compared to traditional water-pipe boilers. | |
The boiler employs high-quality fixed grates engineered to withstand temperatures up to 1200°C. These grates offer exceptional durability, resisting deformation and damage, ensuring a prolonged service life. | |
The Aix boiler is designed with a large-diameter drum and combustion chamber, paired with optimized radiation and convective heating surfaces. This configuration maximizes heat absorption, delivering ample output and superior thermal efficiency. | |
The Aix system includes premium auxiliary equipment such as water treatment units, pumps, dust collectors, and economizers. These components minimize environmental impact, extend boiler lifespan, and provide excellent economic benefits, earning widespread user approval. | |
The Aix boiler features a compact design, occupying significantly less space than boilers of equivalent capacity. This reduces boiler room investment costs by at least one-third, making it ideal for both new installations and retrofitting existing boiler rooms. |
