top 10 boiler manufacturers in world wood, ZOZEN thermal oil heaters become the common choice of many food enterprises

As a domestic well-known industrial boiler manufacturer, ZOZEN has been implementing the Belt and Road initiative all the time. The booming development in overseas market of ZOZEN profits from insisting on technological innovation and cultivating professional technical service team for overseas market.

The ZOZEN WNS series oil-fired steam boiler was successfully delivered to the capital of Caracas, Venezuela in early June. After completing the installation and commissioning the boiler will provide a stable heat source for the production line of Inversiones Goa 7 C.A, further enhancing the efficiency and overall competitiveness of the enterprise.

The DZL series biomass-fired horizontal three-pass water-fire tube chain grate boiler is pre-assembled boiler with a capacity of 2-20 tph (hot water boiler: 1.4-14MW) and a thermal efficiency of over 88%. By extending the furnace arch, increasing the furnace height and adjusting the width and length of grate, ZOZEN takes the lead in solving the problems that easily occur in biomass-fired boilers such as furnace arch collapse, furnace door burnout, hopper tempering and tube wall coking. It has the characteristics of wide fuel adaptability, small covering area, convenient installation and high thermal efficiency, top 10 boiler manufacturers in world wood.

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. 

top 10 boiler manufacturers in world wood, ZOZEN Boiler has invested a lot of technical force in improving boiler’s energy-saving performance. The structure and operating principle of organic heat carrier boiler cause that the exhaust gas temperature at its end is around 300°C and result in a huge waste of heat energy. In order to reduce heat loss, ZOZEN technicians add a variety of energy-saving devices at the end of boiler’s flue gas duct to improve the overall thermal efficiency of organic heat carrier boiler through the recovery and utilization of high-temperature flue gas, which helps many companies to achieve the goal of energy saving and consumption reduction.

After the raw materials are transported to the workshop, steel plates will be precisely cut by the plasma cutting machine according to design drawings. The cut steel plates after finishing three processes of rust removing, edge milling and chamfering will be rolled into workpieces for making drums by this advanced four-axis rolling machine. ZOZEN’s CNC rolling machine can complete the rolling of a drum shell within 90 seconds with a largest thickness of 100mm, an out-of-roundness and angular deviation within 1mm. Its advantages include the predeformation and cylindrical rolling of two plate ends via one-time load, arc work, shaping and leveling work on the sheet metal. It has the effects of direct pre-bending, saving time and materials to ensure the smooth progress of next welding process and further ensure the welding quality.

Being able to realize the long-term and friendly cooperative relationships with customers depends on not only ZOZEN’s technical advantages, but also the service guarantee that ZOZEN promises. For 30 years, ZOZEN has never stopped its pace of service improvement. In addition to the service commitment of “arriving at the site within 2 hours, maintenance for free in 12 months and 24-hour hotline standby”, ZOZEN also builds a comprehensive customer information feedback system to solve users’ problems and improve the user experience. What’s more, ZOZEN regularly implements return visit activities which are invested huge manpower and material resources to close to customers, understand their demands, solve their problems and optimize their operation parameters, which wins the wide recognition of ZOZEN users. Good quality and service ensure the future of ZOZEN.
