DZL series package boilers are horizontal three-pass water & fire tube boilers with a chain grate stoker structure. Threaded pyrotechnic tubes are arranged in the drum to form a convection heating surface, while the drum and the water walls on both sides form a radiation heating surface in the furnace. Each package system is fully installed and wired before being transported to site and is electrically controlled to provide functions such as stepless speed regulation for the stoker, threshold parameter alert and interlock protection.
DZL series coal-fired steam boiler Introduction
1. Boilers Features
- Strong output and be steady
- Small dimension and space-saving
- No need special protection when power failure happens suddenly
- High heat efficiency
- Rapid heating
- Lower emission
- Short installation time
2. Control Systems
- The control and safety systems are interlocked in an electric control cabinet.
- Sound-light alarm of high and super-high steam pressure;
- Sound-light alarm of high and lowe water limit level;
- Sound-light alarm of pressure loss in the water pumps;
- More safety devices are designed and connected with the electric control cabinet (ECC). More details will be explained in the ECC Manual.
