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. CNC manufacturing technology
2. The vertical and circumferential seam welding of the boiler adopts advanced automatic submerged arc welding technology to ensure the welding quality. All vertical and circumferential welds are subjected to 100% ray detection.
3. The flange of the socket is welded by robots.
4. Advanced manufacturing technology, using assembly line automatic spinning operation.
5. reasonable manhole and hand hole layout, easy to maintenance. Furnaces are equipped with access doors for easy access and maintenance.
6. The flue gas will be exhausted from the rear smoke box finally, this design fundamentally solves the problem of cracking of the tube sheet of a pure fire tube boiler.
