sketch of oil boiler, ZOZEN improves the thermal efficiency of gas-fired boilers to more than 98%

During the "Thirteenth Five-Year Plan" period, China's oil refining industry will focus on transformation and upgrading, and continue to enhance comprehensive strength. It will vigorously eliminate backward production capacity and improve the scale and technology of its units. Among them, the boiler as an important piece of energy equipment is indispensable in the petroleum refining process, sketch of oil boiler.

sketch of oil boiler, ZOZEN YLW series thermal oil heater is of square coil tube vertical type chain grate, it consists of two separate parts - chain grate stoker and heater body. After erection on site, it only needs to connect to thermal oil piping and electricity to start operation. The heater adopts chain grate to perform mechanical fuel feeding, equipped with FD fan and ID fan for air ventilation, and also equipped with slay discharger to remove the bottom slag.

With thermal efficiency over 82% and NOx emissions less than 100mg/Nm3, ZOZEN DZL series boilers feature high efficiency and low emissions. They adopt single-drum structure and a chain grate. The heat transfer coefficient of threaded smoke tubes is 1.8 times higher than ordinary tubes. In order to expand the capacity, PT. New Hope Indonesia introduced ZOZEN DZL series coal-fired steam boiler to provide efficient and reliable heat source guarantee for feed production. 

The structural design focuses more on details. The sealing of both sides of membrane wall and drums adopt comb plate. The boiler features a drainage system of condensation water in convection zone to prevent the corrosion of furnace body by acid condensate. Advantages: reduce the frequent maintenance of furnace and extend the boiler working life.

During the production process, the CNC cutting rate of ZOZEN has reached more than 80%, which provides a strong guarantee for the welding and assembly quality of the boiler. Compared with flame cutting, the underwater plasma cutting used by ZOZEN has no deformation and splashing, which further improves the assembly accuracy between the components of the boiler, thereby achieving accurate assembly of the entire boiler.

Be it a firetube, watertube, hot water, or steam boiler, they are all effective and efficient in their own unique ways. To learn in more detail about the differences between boiler types, visit the section on ZOZEN website.
