In the production process of paper products, the links such as cooking, drying and forming all require the support of high-quality steam, and boiler equipment is essential. As a partner of many papermaking enterprises, the environmentally friendly gas-fired boilers produced by ZOZEN Boiler have effectively helped enterprises to complete the transformation and upgrading of their heating systems and formed a high-quality development model that is environmentally friendly, energy-saving and green.
ZOZEN can complete the task with high efficiency and high quality through automatic production equipment, and the delivery cycle of boiler is short. In addition, ZOZEN gas steam boiler realizes safe and automatic operation through intelligent control system and interlocking device.
In order to improve employees' awareness of safety in production, ZOZEN Boiler has adopted a safety education system, which is divided into three levels: factory level, workshop level and team level. At the daily team meeting, the team leader takes safety production as an important meeting content to publicize, further clarifies the responsibility for safety production, to improve the safety awareness and sense of responsibility of employees, and to avoid accidents in production. Welding in limited space is a common work environment for ZOZEN workers. Therefore, the frontline workers will dress well with the protection masks and long-sleeve overalls.
According to the specific conditions of the pulp and paper industry, ZOZEN boiler provides boilers with high combustion efficiency and low operating cost and is recognized by paper enterprises. The advanced boiler automatic controller, man-machine interface, users only need to set easily, the boiler can start and stop, regulate load and according to user requirements, load regulation, automatic water supply and other fully automatic operation.
In 2020, ZOZEN Boiler successfully supplied boilers in Venezuela, Thailand, Afghanistan, Karachi, Zimbabwe and many other countries. Especially in Afghanistan, ZOZEN provided one set of SZL series coal-fired steam boiler for Baheer Group, providing heat source for the paper production line. It successfully passed the environmental protection inspection organized by Afghan government, which had been proved to meet the local environmental protection standards due to the high combustion efficiency and super-clean flue gas emissions.
In Sri Lanka, a set of ZOZEN 15 tph DZW series biomass-fired steam boiler was being installed and debugged. The user is a well-known local palm oil manufacturer, AEN PALM OIL PROCESSING (PVT) LTD. The boiler fuel is palm fiber. The boiler is a tri-drum boiler which has characteristics of no ash accumulation, high efficiency and good environmental protection performance. There is no need to stop the boiler for dust removal, which can make the boiler keep the normal operation for a long time. Meanwhile, considering the combustion characteristics of palm fiber, ZOZEN technicians also optimize the feeding hopper, furnace arch and air distribution device of the boiler to solve the coking problem caused by the fuel combustion.
ZOZEN SZS series steam boiler is a kind of D-type chamber structure boiler with longitudinal double drums. It has a big combustion chamber equipped with the low emission burner to effectively reduce the NOx. It also adopts the full membrane tube wall structure and pressurized combustion without smoke mixture.
Recently, ZOZEN took a field trip at the project location of the WNS boiler. The ZOZEN WNS series gas-fired steam boilers are horizontal wetback fire-tube boilers which have reasonable internal structure. An advanced low NOx burner is equipped with the boiler to reduce the NOx emission to less than 30mg/Nm3. At the same time, the burner can realize automatic air adjustment, which can ensure the sufficient fuel combustion.
