Technical Features  SZL Boiler 

Intelligent Combustion Control System

1. Multi-zone air distribution: Air is supplied in sections along the grate length, with independent airflow control for each zone.

2. Real-time oxygen monitoring: Combustion air is automatically adjusted based on flue gas oxygen content to maintain optimal combustion.

3. Layered temperature control: Different grate zones are temperature-controlled to prevent local overheating and slagging.

Anti-Slagging Design

1. Optimized front and rear arches: Enhance heat radiation and gas mixing for stable ignition.

2. Special grate bars: High-temperature and oxidation resistant, with clinker-breaking structure.

3. Multi-stage ash cleaning: Combination of mechanical cleaning and soot blowers keeps heating surfaces clean.
