  • Description

    DZL series package boiler is a horizontal three-pass water and fire pipe chain grate boiler, which uses medium-sized bituminous coal. The boiler body is vertical single drum, and the threaded pyrotechnic tube is arranged in the drum to form a convection heating surface, and the drum and the water walls on both sides constitute a radiation heating surface of the furnace.

    The combustion equipment uses light chain grate, the whole package is finished in the factory. The electric control makes the governor stepless speed regulation, the limit parameter alarm and the interlock protection.

    Technical advantages

    1. Steel pipe cutting, thread pipe pressing and convection pipe processing all adopt advanced numerical control technology.

    2. The layout of chain grate is neat and beautiful, result in front and rear smoke box panel using CNC plasma cutting machine.

    3. The flange of the socket is welded by robots.

    4. The chain grate is manufactured by our factory, and it is tested for 72 hours before leaving the factory to ensure that the tightness is moderate and won’t go wrong.

    5. Advanced manufacturing technology, using assembly line automatic spinning operation.

    6. The independent secondary draft fan makes it easy to control and adjust the wind volume and pressure.

    7. Abundant auxiliary configuration
