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.
Feature
1. The layout of chain grate is neat and beautiful, result in front and rear smoke box panel using CNC plasma cutting machine.
2. The flange of the socket is welded by robots.
3. 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.
4. The air volume accounts for about 30% of the total, and the wind speed is about 50m³.
5. The flue gas cooled by the eight-character flue then enters the threaded tube (in this case the fire tube type) arranged in the drum from the front smoke box.
