AI Technical Summary
Existing duct heating technology suffers from problems such as low heat exchange efficiency, uneven airflow distribution, high maintenance costs, high contact thermal resistance, and easy detachment when operating coal-fired power units at low loads. It is difficult to adapt to the large-scale load changes required under deep peak shaving conditions, thus affecting the boiler's stable combustion performance at low loads.
The design adopts a zero thermal resistance spiral finned tube, which is integrally formed by medium frequency extrusion process and seamlessly connected to the base tube. Combined with the flow guiding mechanism and intelligent temperature control system, it can achieve uniform airflow distribution and precise temperature control, thereby enhancing the sealing and stability of the equipment.
It improves heat exchange efficiency by more than 25%, controls airflow distribution uniformity within ±5%, extends equipment service life, ensures stable combustion performance of boilers under low load, and reduces equipment maintenance costs.
