3 ton heavy oil steam boiler, ZOZEN Boiler is a leading industrial boiler manufacturer in the domestic boiler market

Under the background of increasingly fierce market competition and rising comprehensive costs, Mengniu Dairy always adheres to the concept of sustainable development. When purchasing boiler equipment, it uses clean energy natural gas as fuel to reduce environmental pollution. So far, Mengniu Dairy has purchased more than ten sets of WNS series gas-fired steam boilers from ZOZEN.
3 ton heavy oil steam boiler, ZOZEN DZL series coal-fired steam boilers are horizontal three-pass water-fire-tube chain grate boilers. Threaded smoke tubes are arranged in the drum to form a convection heating surface. The drum and the water-cooled walls on both sides form a furnace radiation heating surface.
The thermal oil heater is also known as an organic heat carrier boiler. It uses the thermal oil as a heat medium and uses a hot oil circulation pump to force the medium to circulate in the liquid phase. After transferring the thermal energy to the heating equipment, the thermal oil returns to the furnace to be reheated. With the feature of low-pressure and high-temperature heating, the thermal oil heater has wide applications. ZOZEN has provided thermal oil heaters to many building material companies, such as Huayuan Mineral Wool Board, Ameisizhuang Mineral Wool Board, Shanghai High-New Science & Technology and etc.
Designed to wrap the whole furnace body for heat preservation. There are no heat transfer supports between the furnace body and the outside surface. The appearance is mirror polished stainless steel with a protective coating. After the boiler is installed, remove the coating and show the mirror polished stainless steel appearance. Advantages: a good-looking appearance, low temperature of surface, low heat dissipation.
The automated numerical control coil production line of ZOZEN ensures that the coil is one-time formation. ZOZEN also has national patented hydraulic shaping equipment, a 90-degree flip hydraulic test platform, hydraulic lift, 360-degree rotating ultra-high-precision assembly production lines, and a large number of highly qualified technical workers, which ensure the manufacturing quality and prolong the service life of boilers, 3 ton heavy oil steam boiler.
One applies his knowledge to practice and his knowledge advances together with practice. Through the internal training, ZOZEN’s leaders should grasp the opportunity to change their minds, understand the essence of training and apply what they learned to practice in order to better promote the process of ZOZEN Boiler Lean Factory Standardization Project, enhance ZOZEN’s core competitiveness and help ZOZEN Boiler go further and more steadily in the fierce market competition.
