QUALITY & SAFETY

 Water Level electrode safely controls boiler operation in the event of a low water Condition; Safety enhanced by the advanced interlock Control system.

Seven checks are set and each one is Supervised by a dedicated inspector. Any work that fails to pass the inspection Cannot proceed to next step.

Our production lines have the highest level of Automation in China and operate under a strict quality management system so that each coal-fired steam boiler produced by ZOZEN is designed to withstand Continuous operation in harsh industrial environments.

EXCELLENT THERMAL EFFICIENCY

the coal-fired steam boiler Achieves maximum efficiencies by circulating the flue gases through the boiler 3 times. the longer flue gases stay in the boiler, the higher the efficiency Achieved.

Self-developed thread smoke tubes force Flue gases to stay longer in the coal-fired steam boiler, transfer coefficient is 1.8 times higher than common smoke tubes.

Chain grate stoker grate-firing burning Assures complete combustion of fuel.

Thermal efficiency is 5%~15% higher Than other coal-fired steam boilers, you will save as high as USD70,000 annual Fuel cost for each 10 tph boiler.

EASE of OPERATION & MAINTENANCE

Easy coaling and deslagging, CTV fire Grates, high automation in operation that requires less involvement of Operational and maintenance personnel

Rugged stainless steel design, your Coal-fired steam boiler is elegant and durable.

SAVE YOUR MONEY & TIME

the coal-fired steam boiler is Designed, manufactured, and packaged by ZOZEN. All components are shipped as a Package, ready for immediately operation after installation.

the coal-fired steam boiler comes in a compact design, suit for the situations when construction budgets or Boiler rooms are tight.

Feeding system, slag discharge System, flue gas treatment system and boiler house layout plans are available for ZOZEN boilers, making them easy to customize to fit your unique needs.
