ZOZEN WNS series gas-fired (oil-fired) boilers are wetback fire-tube boilers with a two-pass or three-pass design. It uses threaded smoke tube for heat transfer and manages to achieve a thermal efficiency up to 98%. The economizer is installed at the tail of boiler, giving the boiler a compact size. Meanwhile, sound automatic control system enables unattended operation.

In the rubber industry, steam boilers are widely used in the processes of rubber calendering, vulcanizing and drying. PT.Industri Karet Deli is a large rubber enterprise in Indonesia, it planned to upgrade production equipment to improve their core competence. The company contacted ZOZEN and signed the purchase contract of SZL 20 tph SZL series coal-fired boiler. This series of water tube boilers adopts unique grate bars and appropriate air registers to ensure the stable running of boilers and improve the thermal efficiency.

fire tube natural gas fired 4 ton steam boiler, ZOZEN WNS series gas fired boiler not only adopts advanced low NOx burners. And through the flue gas recirculation technology, about 10% -30% of the flue gas at the tail of the boiler is sucked into the air inlet of the burner through the flue gas pipe, mixed with the combustion-supporting air, and then entering the furnace, thereby reducing the temperature and oxygen concentration in the combustion area, and finally reducing The amount of thermal NOx is generated, and the NOx in the tail gas of the boiler are less than 30mg/Nm3, which meets the requirements of low nitrogen emissions of the enterprise.enterprise.

ZOZEN has set up a total of seven process stopping points throughout the production process, which are strictly controlled by different engineers, independent of each other and supervised each other, so that problems can be found and solved in time.
