3 pass diesel boiler, ZOZEN biomass-fired boiler has good quality
ZOZEN is always committed to doing every detail well and creating value for users. Since the company was founded in 1988, ZOZEN has reformed the traditional production mode of industrial boiler industry and introduced modern science and technology to realize the mechanization, informatization and intelligentization of boiler production line. The fully automatic production lines greatly improve the production efficiency. More importantly, it also enhances the size precision of boiler parts processing and reduces the product quality problems caused by human factors.

The DZL series coal-fired horizontal three-pass water-fire tube chain grate boiler is pre-assembled boiler which is safe and efficient with a thermal efficiency of over 82%. The boiler body is a single drum longitudinal layout. Thread smoke tubes in the drum form the convection heating surface while the drum and water-cooled walls on both sides form the radiation heating surface of the furnace. The combustion equipment adopts the light chain grate. It has the characteristics of wide coal adaptability, small covering area, convenient installation and high thermal efficiency.
Recently, ZOZEN YQW series thermal oil heaters gained favor of SOTRATECH in Mauritius, which is an energy company engaged in utilization and development of sustainable energy. This time SOTRATECH wanted to purchase one thermal oil heater for a local textile mill, providing heat energy for dying, printing, drying and other production progresses. The director of SOTRATECH said that ZOZEN thermal oil heater featured advanced production technology and strict quality test standards, then he ordered a set of 2.8MW YQW series gas-fired thermal oil heater from ZOZEN.
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, 3 pass diesel boiler.
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.
In the future, ZOZEN will continue to play its own Advantages in the field of industrial boiler manufacturing and provide high-quality boiler products for more enterprises to lay a solid foundation for development, 3 pass diesel boiler.
