Introduction
ZOZEN ZZ series water tube steam boiler adopts the "D" type structure. The furnace is on the right side and the convection tube bundle is on the left. Around the furnace is the membrane water wall. The boiler is equipped with an advanced burner, an economizer and a condenser, which can improve the thermal efficiency to more than 98% and reduce the NOx emission to less than 30mg/Nm³. With an automatic control system, the boiler can achieve unattended operation.
- Manhole, Inspection Door
- Manholes at top and bottom of boiler drum, inspection door at rear of boiler
- Easy to open for boiler maintenance and cleaning
- Membrane Wall Structure
- Boiler body with membrane walls for front and rear, increasing lifespan to over 20 years
- Sealed welding prevents smoke and water leakage
- Safety Devices
- Equipped with the explosion door and flame sensor
- Water level regulation, alarms (high/low water, over-pressure) etc.
- Combustion Chamber
- Using full membrane water-cooled walls for enhanced heat transfer
- Micro-positive pressure combustion, no smoke, pollution-free operation
- Minimal heat loss from the boiler body
- Adopt high-quality aluminium silicate fibre and refractory mortar for insulation
- Self-supporting steel frame structure, no heat transfer supports between furnace body and outer surfaces
- High Quality Steam
- Optimal steam drum and separator configuration minimize steam carryover
- Ensures high-quality steam and improves thermal efficiency
Following the concept of energy conservation and environmental protection, ZOZEN Boiler has innovatively developed the "O" type medium temperature and medium pressure oil/gas steam boiler, which has obtained a national utility model patent (Patent No.: CN202021759997.6). The boiler adopts chamber combustion technology with a horizontal layout of the furnace, presenting an "O" shape.
